Thomas Cranmer

Henry VIII's first marriage had its origins in 1502 when his elder brother, Arthur, died. Their father, Henry VII, then betrothed Arthur's widow, Catherine of Aragon, to the future king. The betrothal immediately raised questions related to the biblical prohibition (in Leviticus 18 and 20) against marriage to a brother's wife. The couple married in 1509 and after a series of miscarriages, a daughter, Mary, was born in 1516. By the 1520s, Henry still did not have a son to name as heir and he took this as a sure sign of God's anger and made overtures to the Vatican about an annulment. He gave Cardinal Wolsey the task of prosecuting his case; Wolsey began by consulting university experts. From 1527, in addition to his duties as a Cambridge don, Cranmer assisted with the annulment proceedings.

Today historians know nothing definite about Cranmer's early schooling. He probably attended a grammar school in his village. At the age of fourteen, two years after the death of his father, he was sent to the newly created Jesus College, Cambridge. It took him eight years to reach his Bachelor of Arts degree following a curriculum of logic, classical literature and philosophy. During this time, he began to collect medieval scholastic books, which he preserved faithfully throughout his life. For his master's degree he studied the humanists, Jacques Lefèvre d'Étaples and Erasmus. He finished the course in three years. Shortly after receiving his Master of Arts degree in 1515, he was elected to a Fellowship of Jesus College.

Sometime after Cranmer took his MA, he married a woman named Joan. Although he was not yet a priest, he was forced to forfeit his fellowship, resulting in the loss of his residence at Jesus College. To support himself and his wife, he took a job as a reader at Buckingham Hall (later reformed as Magdalene College). When Joan died during her first childbirth, Jesus College showed its regard for Cranmer by reinstating his fellowship. He began studying theology and by 1520 he had been ordained, the university already having named him as one of their preachers. He received his Doctor of Divinity degree in 1526.

Not much is known about Cranmer's thoughts and experiences during his three decades at Cambridge. Traditionally, he has been portrayed as a humanist whose enthusiasm for biblical scholarship prepared him for the adoption of Lutheran ideas, which were spreading during the 1520s. A study of his marginalia reveals an early antipathy to Martin Luther and an admiration for Erasmus. When Cardinal Wolsey, the king's Lord Chancellor, selected several Cambridge scholars, including Edward Lee, Stephen Gardiner and Richard Sampson, to be diplomats throughout Europe, Cranmer was chosen to take a minor role in the English embassy in Spain. Two recently discovered letters written by Cranmer describe an early encounter with the king, Henry VIII of England: upon Cranmer's return from Spain, in June 1527, the king personally interviewed Cranmer for half an hour. Cranmer described the king as "the kindest of princes".

In January 1532, Cranmer was appointed the resident ambassador at the court of the Holy Roman Emperor, Charles V. As the emperor travelled throughout his realm, Cranmer had to follow him to his residence in Regensburg. He passed through the Lutheran city of Nuremberg and saw for the first time the effects of the Reformation. When the Imperial Diet was moved to Nuremberg, he met the leading architect of the Nuremberg reforms, Andreas Osiander. They became good friends, and during that July Cranmer took the surprising action of marrying Margarete, the niece of Osiander's wife. He did not take her as his mistress, as was the prevailing custom with priests for whom celibacy was too rigorous. Scholars note that Cranmer had moved, however moderately at this stage, into identifying with certain Lutheran principles. This progress in his personal life was not matched in his political life as he was unable to persuade Charles, Catherine's nephew, to support the annulment of his aunt's marriage.

It is difficult to assess how Cranmer's theological views had evolved since his Cambridge days. There is evidence that he continued to support humanism; he renewed Erasmus' pension that had previously been granted by Archbishop Warham. In June 1533, he was confronted with the difficult task of not only disciplining a reformer, but also seeing him burnt at the stake. John Frith was condemned to death for his views on the eucharist: he denied the real presence. Cranmer personally tried to persuade him to change his views without success. Although he rejected Frith's radicalism, by 1534 he clearly signalled that he had broken with Rome and that he had set a new theological course. He supported the cause of reform by gradually replacing the old guard in his ecclesiastical province with men who followed the new thinking such as Hugh Latimer. He intervened in religious disputes, supporting reformers to the disappointment of religious conservatives who desired to maintain the link with Rome.

Cranmer was not immediately accepted by the bishops within his province. When he attempted a canonical visitation, he had to avoid locations where a resident conservative bishop might make an embarrassing personal challenge to his authority. In 1535, Cranmer had difficult encounters with several bishops, John Stokesley, John Longland, and Stephen Gardiner among others. They objected to Cranmer's power and title and argued that the Act of Supremacy did not define his role. This prompted Thomas Cromwell, the king's chief minister, to activate and to take the office of the vicegerent, the deputy supreme head of ecclesiastical affairs. He created another set of institutions that gave a clear structure to the royal supremacy. Hence, the archbishop was eclipsed by Vicegerent Cromwell in regards to the king's spiritual jurisdiction. There is no evidence that Cranmer resented his position as junior partner. Although he was an exceptional scholar, he lacked the political ability to outface even clerical opponents. Those tasks were left to Cromwell.

On 29 January 1536, when Anne miscarried a son, the king began to reflect again on the biblical prohibitions that had haunted him during his marriage with Catherine of Aragon. Shortly after the miscarriage, the king started to take an interest in Jane Seymour. By 24 April, he had commissioned Cromwell to prepare the case for a divorce. Unaware of these plans, Cranmer had continued to write letters to Cromwell on minor matters up to 22 April. Anne was sent to the Tower of London on 2 May, and Cranmer was urgently summoned by Cromwell. On the very next day, Cranmer wrote a letter to the king expressing his doubts about the queen's guilt, highlighting his own esteem for Anne. After it was delivered, Cranmer was resigned to the fact that the end of Anne's marriage was inevitable. On 16 May, he saw Anne in the Tower and heard her confession and the following day, he pronounced the marriage null and void. Two days later, Anne was executed; Cranmer was one of the few who publicly mourned her death.

In late 1536, the north of England was convulsed in a series of uprisings collectively known as the Pilgrimage of Grace, the most serious opposition to Henry's policies. Cromwell and Cranmer were the primary targets of the protesters' fury. Cromwell and the king worked furiously to quell the rebellion, while Cranmer kept a low profile. After it was clear that Henry's regime was safe, the government took the initiative to remedy the evident inadequacy of the Ten Articles. The outcome after months of debate was The Institution of a Christian Man informally known from the first issue as the Bishops' Book. The book was initially proposed in February 1537 in the first vicegerential synod, ordered by Cromwell, for the whole Church. Cromwell opened the proceedings, but as the synod progressed, Cranmer and Foxe took on the chairmanship and the co-ordination. Foxe did most of the final editing and the book was published in late September.

In 1538, the king and Cromwell arranged with Lutheran princes to have detailed discussions on forming a political and religious alliance. Henry had been seeking a new embassy from the Schmalkaldic League since mid-1537. The Lutherans were delighted by this and they sent a joint delegation from various German cities, including a colleague of Martin Luther, Friedrich Myconius. The delegates arrived in England on 27 May 1538. After initial meetings with the king, Cromwell, and Cranmer, discussions on theological differences were transferred to Lambeth Palace under Cranmer's chairmanship. Progress on an agreement was slow partly due to Cromwell being too busy to help expedite the proceedings and partly due to the negotiating team on the English side, which was evenly balanced between conservatives and reformers. The talks dragged on with the Germans becoming weary despite the Archbishop's strenuous efforts. The negotiations were fatally neutralised by an appointee of the king. Cranmer's colleague, Edward Foxe, who sat on Henry's Privy Council, had died earlier in the year. The king chose as his replacement Cranmer's conservative rival, Cuthbert Tunstall, who was told to stay near Henry to give advice. On 5 August, when the German delegates sent a letter to the king regarding three items that particularly worried them (compulsory clerical celibacy, the withholding of the chalice from the laity, and the maintenance of private masses for the dead), Tunstall was able to intervene for the king and to influence the decision. The result was a thorough dismissal by the king of many of the Germans' chief concerns. Although Cranmer begged the Germans to continue with the negotiations using the argument "to consider the many thousands of souls in England" at stake, they left on 1 October having made no substantial achievements.

Continental reformer Philipp Melanchthon was aware that he was very much admired by Henry. In early 1539, Melanchthon wrote several letters to Henry criticising his views on religion, in particular his support of clerical celibacy. By late April another delegation from the Lutheran princes arrived to build on Melanchthon's exhortations. Cromwell wrote a letter to the king in support of the new Lutheran mission. The king had begun to change his stance and concentrated on wooing conservative opinion in England rather than reaching out to the Lutherans. On 28 April 1539, Parliament met for the first time in three years. Cranmer was present, but Cromwell was unable to attend due to ill health. On 5 May the House of Lords created a committee with the customary religious balance between conservatives and reformers to examine and determine doctrine. The committee was given little time to do the detailed work needed for a thorough revision. On 16 May, the Duke of Norfolk noted that the committee had not agreed on anything, and proposed that the Lords examine six doctrinal questions—which eventually formed the basis of the Six Articles. They affirmed the conservative interpretation of doctrines such as the real presence, clerical celibacy, and the necessity of auricular confession, the private confession of sins to a priest. As the Act of the Six Articles neared passage in Parliament, Cranmer moved his wife and children out of England to safety. Up until this time, the family was kept quietly hidden, most likely in Ford Palace in Kent. The Act passed Parliament at the end of June and it forced Latimer and Nicholas Shaxton to resign their dioceses given their outspoken opposition to the measure.

The setback for the reformers was short-lived. By September, Henry was displeased with the results of the Act and its promulgators; the ever-loyal Cranmer and Cromwell were back in favour. The king asked his archbishop to write a new preface for the Great Bible, an English translation of the Bible that was first published in April 1539 under the direction of Cromwell. The preface was in the form of a sermon addressed to readers. As for Cromwell, he was delighted that his plan of a royal marriage between Henry and Anne of Cleves, the sister of a German prince was accepted by the king. In Cromwell's view, the marriage could potentially bring back contacts with the Schmalkaldic League. Henry was dismayed with Anne when they first met on 1 January 1540 but married her reluctantly on 6 January in a ceremony officiated by Cranmer. The marriage ended in disaster as Henry decided that he would request a royal divorce. This resulted in Henry being placed in an embarrassing position and Cromwell suffered the consequences. His old enemies, including the Duke of Norfolk, took advantage of the weakened Cromwell and he was arrested on 10 June. He immediately lost the support of all his friends, including Cranmer. As Cranmer had done for Anne Boleyn, he wrote a letter to the king defending the past work of Cromwell. Henry's marriage to Anne of Cleves was quickly annulled on 9 July by the vice-gerential synod, now led by Cranmer and Gardiner.

Cranmer's family had been exiled to the Continent in 1539. It is not known exactly when they returned to England, but it was soon after the accession of Edward VI in 1547 that Cranmer publicly acknowledged their existence. Not much is known about the early years of the children. His daughter, Margaret, was likely born in the 1530s and his son, Thomas, came later, probably during the reign of Edward. Around the time of Mary's accession, Cranmer's wife, Margarete, escaped to Germany, while his son was entrusted to his brother, Edmund Cranmer, who took him to the Continent. Margarete Cranmer eventually married Cranmer's favourite publisher, Edward Whitchurch. The couple returned to England after Mary's reign and settled in Surrey. Whitchurch also negotiated for the marriage of Margaret to Thomas Norton. Whitchurch died in 1562 and Margarete married for the third time to Bartholomew Scott. She died in the 1570s. Both of Cranmer's children died without issue and his line became extinct.

Following the annulment, Cromwell was executed on 28 July. Cranmer now found himself in a politically prominent position, with no one else to shoulder the burden. Throughout the rest of Henry's reign, he clung to Henry's authority. The king had total trust in him and in return, Cranmer could not conceal anything from the king. At the end of June 1541, Henry with his new wife, Catherine Howard, left for his first visit to the north of England. Cranmer was left in London as a member of a council taking care of matters for the king in his absence. His colleagues were Lord Chancellor Thomas Audley and Edward Seymour, Earl of Hertford. This was Cranmer's first major piece of responsibility outside the Church. In October, while the king and queen were away, a reformer named John Lascelles revealed to Cranmer that Catherine engaged in extramarital affairs. Cranmer gave the information to Audley and Seymour and they decided to wait until Henry's return. Afraid of angering the king, Audley and Seymour suggested that Cranmer inform Henry. Cranmer slipped a message to Henry during mass on All Saints Day. An investigation revealed the truth of the marital indiscretions and Catherine was executed in February 1542.

In 1543, several conservative clergymen in Kent banded together to attack and denounce two reformers, Richard Turner and John Bland, before the Privy Council. They prepared articles to present to the council, but at the last moment, additional denunciations were added by Stephen Gardiner's nephew, Germain Gardiner. These new articles attacked Cranmer and listed his misdeeds back to 1541. This document and the actions that followed were the basis of the so-called Prebendaries' Plot. The articles were delivered to the Council in London and were probably read on 22 April 1543. The king most likely saw the articles against Cranmer that night. The archbishop appeared unaware that an attack on his person was made. His commissioners in Lambeth dealt specifically with Turner's case where he was acquitted, much to the fury of the conservatives.

For five months, Henry took no action on the accusations against his archbishop. The conspiracy was finally revealed to Cranmer by the king himself. According to Cranmer's secretary, Ralph Morice, sometime in September 1543 the king showed Cranmer a paper summarising the accusations against him. An investigation was to be mounted and Cranmer was appointed chief investigator. Surprise raids were carried out, evidence gathered, and ringleaders identified. Typically, Cranmer put the clergymen involved in the conspiracy through immediate humiliation, but he eventually forgave them and continued to use their services. To show his trust in Cranmer, Henry gave Cranmer his personal ring. When the Privy Council arrested Cranmer at the end of November, the nobles were stymied by the symbol of the king's trust in him. Cranmer's victory ended with two second-rank leaders imprisoned and Germain Gardiner executed.

With the atmosphere in Cranmer's favour, he pursued quiet efforts to reform the Church, particularly the liturgy. On 27 May 1544 the first officially authorised vernacular service was published, the processional service of intercession known as the Exhortation and Litany. It survives today with minor modifications in the Book of Common Prayer. The traditional litany uses invocations to saints, but Cranmer thoroughly reformed this aspect by providing no opportunity in the text for such veneration. Additional reformers were elected to the House of Commons and new legislation was introduced to curb the effects of the Act of the Six Articles and the Act for the Advancement of True Religion.

In 1546, the conservatives in a coalition including Gardiner, the Duke of Norfolk, the Lord Chancellor Wriothesley, and the bishop of London, Edmund Bonner, made one last attempt to challenge the reformers. Several reformers with links to Cranmer were targeted. Some such as Lascelles were burnt at the stake. Powerful reform-minded nobles Edward Seymour and John Dudley returned to England from overseas and they were able to turn the tide against the conservatives. Two incidents tipped the balance. Gardiner was disgraced before the king when he refused to agree to exchange episcopal estates, and the son of the Duke of Norfolk was charged with treason and executed. There is no evidence that Cranmer played any part in these political games, and there were no further plots as the king's health ebbed in his final months. Cranmer performed his final duties for the king on 28 January 1547 when he gave a reformed statement of faith while gripping Henry's hand instead of giving him his last rites. Cranmer mourned Henry's death and it was later said that he demonstrated his grief by growing a beard. The beard was also a sign of his break with the past. Continental reformers grew beards to mark their rejection of the old Church and this significance of clerical beards was well understood in England. On 31 January, he was among the executors of the king's final will that nominated Edward Seymour as Lord Protector and welcomed the boy king, Edward VI.

Under the regency of Seymour, the reformers were now part of the establishment. A royal visitation of the provinces took place in August 1547 and each parish that was visited was instructed to obtain a copy of the Homilies. This book consisted of twelve homilies of which four were written by Cranmer. His reassertion of the doctrine of justification by faith elicited a strong reaction from Gardiner. In the "Homily of Good Works annexed to Faith", Cranmer attacked monasticism and the importance of various personal actions involved in liturgical recitations and ceremonies. Hence, he narrowed the range of good works that would be considered necessary and reinforced the primacy of faith. In each parish visited, injunctions were put in place that resolved to, "...eliminate any image which had any suspicion of devotion attached to it."

As the use of English in worship services spread, the need for a complete uniform liturgy for the Church became evident. Initial meetings to start what would eventually become the 1549 Book of Common Prayer were held in the former abbey of Chertsey and in Windsor Castle in September 1548. The list of participants can only be partially reconstructed, but it is known that the members were balanced between conservatives and reformers. These meetings were followed by a debate on the Eucharist in the House of Lords which took place between 14 and 19 December. Cranmer publicly revealed in this debate that he had abandoned the doctrine of the corporeal real presence and believed that the Eucharistic presence was only spiritual. Parliament backed the publication of the Prayer Book after Christmas by passing the Act of Uniformity 1549; it then legalized clerical marriage.

In March 1549, the city of Strasbourg forced Martin Bucer and Paul Fagius to leave. Cranmer immediately invited the men to come to England and promised that they would be placed in English universities. When they arrived on 25 April, Cranmer was especially delighted to meet Bucer face to face after eighteen years of correspondence. He needed these scholarly men to train a new generation of preachers as well as assist in the reform of liturgy and doctrine. Others who accepted his invitations include the Polish reformer, Jan Łaski, but Cranmer was unable to convince Osiander and Melanchthon to come to England.

The use of the new Prayer Book was made compulsory on 9 June 1549. This triggered a series of protests in Devon and Cornwall where the English language was not yet in common usage, now known as the Prayer Book Rebellion. By early July, the uprising had spread to other parts in the east of England. The rebels made a number of demands including the restoration of the Six Articles, the use of Latin for the mass with only the consecrated bread given to the laity, the restoration of prayers for souls in purgatory, and the rebuilding of abbeys. Cranmer wrote a strong response to these demands to the King in which he denounced the wickedness of the rebellion. On 21 July, Cranmer commandeered St Paul's Cathedral where he vigorously defended the official Church line. A draft of his sermon, the only extant written sample of his preaching from his entire career, shows that he collaborated with Peter Martyr on dealing with the rebellion.

The Prayer Book Rebellion and other events had a negative effect on the Seymour regency. The Privy Council became divided when a set of dissident Councillors banded together behind John Dudley in order to oust Seymour. Cranmer and two other Councillors, William Paget, and Thomas Smith initially rallied behind Seymour. After a flurry of letters passed between the two sides, a bloodless coup d'état resulted in the end of Seymour's Protectorship on 13 October 1549. Despite the support of religiously conservative politicians behind Dudley's coup, the reformers managed to maintain control of the new government and the English Reformation continued to consolidate gains. Seymour was initially imprisoned in the Tower, but he was shortly released on 6 February 1550 and returned to the council. The archbishop was able to transfer his former chaplain, Nicholas Ridley from the minor see of Rochester to the diocese of London, while John Ponet took Ridley's former position. Incumbent conservatives were uprooted and replaced with reformers.

Although Bucer assisted in the development of the English Reformation, he was still quite concerned about the speed of its progress. Both Bucer and Fagius had noticed that the 1549 Prayer Book was not a remarkable step forward, although Cranmer assured Bucer that it was only a first step and that its initial form was only temporary. By late 1550, Bucer was becoming disillusioned. Cranmer made sure that he did not feel alienated and kept in close touch with him. This attention paid off during the vestments controversy. This incident was initiated by John Hooper, a follower of Heinrich Bullinger who had recently returned from Zürich. Hooper was unhappy with Cranmer's Prayer Book and Ordinal and he particularly objected to the use of ceremonies and vestments. When the Privy Council selected him to be the Bishop of Gloucester on 15 May 1550, he laid down conditions that he would not wear the required vestments. He found an ally among the Continental reformers in Jan Łaski who had become a leader of the Stranger church in London, a designated place of worship for Continental Protestant refugees. His church's forms and practices had taken reforms much further than Cranmer would have liked. Bucer and Peter Martyr, while they sympathised with Hooper's position, supported Cranmer's arguments of timing and authority. Cranmer and Ridley stood their ground. This led to Hooper's imprisonment and he eventually gave in. He was consecrated on 8 March 1551 according to the Ordinal and he preached before the king in his episcopal garments. Cranmer's vision of reform through careful steps under the authority of the government was maintained.

As in the first Prayer Book, the origins and participants in the work of its revision are obscure, but it was clear that Cranmer led the project and steered its development. It had begun as early as the end of 1549 when the Convocation of Canterbury met to discuss the matter. Late in 1550, the opinions of Martyr and Bucer were sought on how the liturgy might be improved and they significantly influenced the revision. The spiritual presence view was clarified by the use of entirely different words when the communicants are offered the bread and the wine. New rubrics noted that any kind of bread could be used and any bread or wine that remained could be used by the curate, thus disassociating the elements from any physical presence. The new book removed any possibility of prayers for the dead, as such prayers implied support for the doctrine of purgatory. The Act of Uniformity 1552, which authorised the book's use, specified that it be exclusively used from 1 November. The final version was officially published at nearly the last minute, due to Dudley's intervention. While travelling in the north of the country, he met the Scots reformer, John Knox, then based in Newcastle. Impressed by his preaching, Dudley selected him to be a royal chaplain and brought him south to participate in the reform projects. In a sermon before the king, Knox attacked the practice of kneeling during communion. On 27 September 1552, the Privy Council stopped the printing of the new Prayer Book and told Cranmer to revise it. He responded with a long letter using the argument that it was for Parliament with the royal assent to decide any changes in the liturgy. On 22 October, the council decided to keep the liturgy as it is and add the so-called Black Rubric, which explained that no adoration was intended when kneeling at communion.

Cranmer's role in politics was diminishing when on 16 October 1551 Seymour was arrested on charges of treason. In December Seymour was put on trial and although acquitted of treason, he was judged guilty of felony and put to death on 22 January 1552. This was the beginning of the breach between Cranmer and Dudley. It was aggravated during the year by the gradual appropriation of ecclesiastical property by the regency. Even throughout this political turmoil, Cranmer worked simultaneously on three major projects in his reform programme: the revision of canon law, the revision of the Prayer Book, and the formation of a statement of doctrine.

The original Catholic canon law that defined governance within the Church clearly needed revision following Henry's break with Rome. Several revision attempts were made throughout Henry's reign, but these initial projects were shelved as the speed of reform outpaced the time required to work on a revision. As the reformation stabilised, Cranmer formed a committee in December 1551 to restart the work. He recruited Peter Martyr to the committee and he also asked Łaski and Hooper to participate, demonstrating his usual ability to forgive past actions. Cranmer and Martyr realised that a successful enactment of a reformed ecclesiastical law-code in England would have international significance. Cranmer planned to draw together all the reformed churches of Europe under England's leadership to counter the Council of Trent, the Catholic Church's response to the Protestant Reformation. In March 1552, Cranmer invited the foremost Continental reformers, Bullinger, John Calvin, and Melanchthon to come to England and to participate in an ecumenical council. The response was disappointing: Melanchthon did not respond, Bullinger stated that neither of them could leave Germany as it was riven by war between the Emperor and the Lutheran princes, and while Calvin showed some enthusiasm, he said he was unable to come. Cranmer acknowledged Calvin and replied stating, "Meanwhile we will reform the English Church to the utmost of our ability and give our labour that both its doctrines and laws will be improved after the model of holy scripture." One partial manuscript of the project survived that was annotated with corrections and comments by Cranmer and Martyr. When the final version was presented to Parliament, the breach between Cranmer and Dudley was complete and the regent effectively killed the canon law bill in the House of Lords.

The origins of the statement that eventually became the Forty-Two Articles are equally obscure. As early as December 1549, the archbishop was demanding from his bishops subscription to certain doctrinal articles. In 1551 Cranmer presented a version of a statement to the bishops, but its status remained ambiguous. Cranmer did not devote much effort into developing the articles, most likely due to work on the canon law revision. He became more interested once the hope for an ecumenical council began to fade. By September 1552, draft versions of the articles were being worked on by Cranmer and John Cheke, his scholarly friend who was commissioned to translate them into Latin. When the Forty-Two Articles were finally published in May 1553, the title-page declared that the articles were agreed upon by the Convocation and were published by the authority of the king. This was not in fact the case and the mistake was likely caused by miscommunications between the archbishop and the Privy Council. Cranmer complained about this to the council, but the authorities responded by noting that the articles were developed during the time of the Convocation—hence evading a direct answer. The council gave Cranmer the unfortunate task of requiring subscription to the articles from the bishops, many of whom opposed them and pointed out the anomaly of the title-page. It was while Cranmer was carrying out this duty that events unfolded that would render the subscriptions futile.

Edward VI became seriously ill from tuberculosis and the councillors were told that he did not have long to live. In May 1553, the council sent several letters to Continental reformers assuring them that Edward's health was improving. Among the letters was one addressed to Melanchthon inviting him to come to England to take up the Regius Chair in Cambridge which was vacant since the death of Martin Bucer in February 1551. Both Henry VIII and Cranmer had previously failed to convince Melanchthon to come; this time the council made a serious effort by sending him an advance to cover his travel expenses. Cranmer sent a personal letter urging him to take the offer. Despite his plea, Melanchthon never made the voyage to England. While this effort to shore up the reformation was taking place, the council was working to convince several judges to put on the throne Lady Jane Grey, Edward's cousin and a Protestant, instead of Mary, Henry and Catherine of Aragon's daughter and a Catholic. On 17 June 1553 the king made his will noting Jane would succeed him, contravening the Third Succession Act. Cranmer tried to speak to Edward alone, but he was refused and his audience with Edward occurred in the presence of the councillors. Edward told him that he supported what he wrote in his will. Cranmer's decision to support Jane must have occurred before 19 June when royal orders were sent to convene the Convocation for the recognition of the new succession.

On 13 November 1553 Cranmer and four others were brought to trial for treason, found guilty, and condemned to death. Numerous witnesses testified that Cranmer had encouraged heresy and had written heretical works. Throughout February 1554 Jane Grey and other rebels were executed. It was now time to deal with the religious leaders of the reformation, and so on 8 March 1554 the Privy Council ordered Cranmer, Ridley, and Latimer to be transferred to Bocardo prison in Oxford to await a second trial for heresy. During this time Cranmer was able to smuggle out a letter to Martyr who had fled to Strasbourg, the last surviving document written in his own hand. He stated that the desperate situation of the church was proof that it will eventually be delivered and wrote, "I pray that God may grant that we may endure to the end!" Cranmer remained isolated in Bocardo prison for seventeen months before the trial started on 12 September 1555. Although it took place in England, the trial was under papal jurisdiction and the final verdict would come from Rome. Under interrogation, Cranmer admitted to every fact that was placed before him, but he denied any treachery, disobedience, or heresy. The trial of Latimer and Ridley started shortly after Cranmer's but their verdicts came almost immediately and they were burnt at the stake on 16 October. Cranmer was taken to a tower to watch the proceedings. On 4 December, Rome decided Cranmer's fate by depriving him of the archbishopric and giving permission to the secular authorities to carry out their sentence.

In his final days Cranmer's circumstances changed, which led to several recantations. On 11 December, Cranmer was taken out of Bocardo and placed in the house of the Dean of Christ Church. This new environment was very different from that of his two years in prison. He was in an academic community and treated as a guest. Approached by a Dominican friar, Juan de Villagarcía, he debated the issues of papal supremacy and purgatory. In his first four recantations, produced between the end of January and mid-February, Cranmer submitted himself to the authority of the king and queen and recognised the pope as head of the church. On 14 February 1556, he was degraded from holy orders and returned to Bocardo. He had conceded very little and Edmund Bonner was not satisfied with these admissions. On 24 February a writ was issued to the mayor of Oxford and the date of Cranmer's execution was set for 7 March. Two days after the writ was issued, a fifth statement, the first which could be called a true recantation, was issued. Cranmer repudiated all Lutheran and Zwinglian theology, fully accepted Catholic theology including papal supremacy and transubstantiation, and stated that there was no salvation outside the Catholic Church. He announced his joy of returning to the Catholic faith, asked for and received sacramental absolution, and participated in the mass. Cranmer's burning was postponed, and under normal practice of canon law he should have been absolved. Mary decided that no further postponement was possible. His last recantation was issued on 18 March. It was a sign of a broken man, a sweeping confession of sin. Despite the stipulation in canon law that recanting heretics be reprieved, Mary was determined to make an example of Cranmer, arguing that "his iniquity and obstinacy was so great against God and your Grace that your clemency and mercy could have no place with him", and pressed ahead with his execution.

The Marian government produced a pamphlet with all six recantations plus the text of the speech Cranmer was to have made in the University Church. His subsequent withdrawal of his recantations was not mentioned, though what actually happened soon became common knowledge, undermining the effectiveness of Marian propaganda. Similarly, the Protestant party had difficulty in making use of the event, given Cranmer's recantations. The exiles' propaganda concentrated on publishing various specimens of his writings. Eventually John Foxe put Cranmer's story to effective use in 1559, and it features prominently in his Acts and Monuments when it was first printed in 1563.
