society as a whole. Correspondence Most major humanists were prolific letter writers, and Thomas More was no exception. As in the case of his friend Erasmus of Rotterdam, however, only a small portion of his correspondence (about 280 letters) survived. These include everything from personal letters to official government correspondence (mostly in English), letters to fellow humanist scholars (in Latin), several epistolary tracts, verse epistles, prefatory letters (some fictional) to several of More's own works, letters to More's children and their tutors (in Latin), and the so-called "prison-letters" (in English) which he exchanged with his oldest daughter Margaret while he was imprisoned in the Tower of London awaiting execution. More also engaged in controversies, most notably with the French poet Germain de Brie, which culminated in the publication of de Brie's Antimorus (1519). Erasmus intervened, however, and ended the dispute. More also wrote about more spiritual matters. They include: A Treatise on the Passion (a.k.a. Treatise on the Passion of Christ), A Treatise to Receive the Blessed Body (a.k.a. Holy Body Treaty), and De Tristitia Christi (a.k.a. The Agony of Christ). More handwrote the last in the Tower of London while awaiting his execution. This last manuscript, saved from the confiscation decreed by Henry VIII, passed by the will of his daughter Margaret to Spanish hands through Fray Pedro de Soto, confessor of Emperor Charles V. More's friend Luis Vives received it in Valencia, where it remains in the collection of Real Colegio Seminario del Corpus Christi museum. Veneration Catholic Church Pope Leo XIII beatified Thomas More, John Fisher, and 52 other English Martyrs on 29 December 1886. Pope Pius XI canonised More and Fisher on 19 May 1935, and More's feast day was established as 9 July. Since 1970 the General Roman Calendar has celebrated More with St John Fisher on 22 June (the date of Fisher's execution). On 31 October 2000 Pope John Paul II declared More "the heavenly Patron of Statesmen and Politicians". More is the patron of the German Catholic youth organisation Katholische Junge Gemeinde. Anglican Communion In 1980, despite their opposition to the English Reformation, More and Fisher were added as martyrs of the reformation to the Church of England's calendar of "Saints and Heroes of the Christian Church", to be commemorated every 6 July (the date of More's execution) as "Thomas More, scholar, and John Fisher, Bishop of Rochester, Reformation Martyrs, 1535".
