been in contact with Martin Bucer since the time when initial contacts were made with the Schmalkaldic League. Cranmer and Bucer's relationship became ever closer owing to Charles V's victory over the League at Mühlberg, which left England as the sole major nation that gave sanctuary to persecuted reformers. Cranmer wrote a letter to Bucer (now lost) with questions on eucharistic theology. In Bucer's reply dated 28 November 1547, he denied the corporeal real presence and condemned transubstantiation and the adoration of the elements. The letter was delivered to Cranmer by two Italian reformed theologians, Peter Martyr and Bernardino Ochino who were invited to take refuge in England. Martyr also brought with him an epistle written allegedly by John Chrysostom, Ad Caesarium Monachum, which appeared to provide patristic support against the corporeal real presence. These documents influenced Cranmer's thoughts on the eucharist. 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 to assist in the reform of liturgy and doctrine. Others who accepted his invitations included the Polish reformer, Jan Łaski, but Cranmer was unable to convince Osiander and Melanchthon that they should come to England. Book of Common Prayer (1548–1549) 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. It is difficult to ascertain
