Thomas the Apostle

=== Feast days ===
When the feast of Saint Thomas was inserted in the Roman calendar in the 9th century, it was assigned to 21 December. The ''Martyrology of St. Jerome'' mentioned the apostle on 3 July, the date to which the Roman celebration was transferred in 1969, so that it would no longer interfere with the major ferial days of [[Advent]].{{sfn|Catholic Church|1969|p=96}} Traditionalist Roman Catholics (who follow the [[General Roman Calendar of 1960]] or earlier), the [[Lutheran Church]], and many [[Anglicans]] (including members of the [[Episcopal Church (United States)|Episcopal Church]] as well as members of the [[Church of England]] who worship according to the 1662 edition of the [[Book of Common Prayer]]),<ref name="commonprayer.org" /> still celebrate his feast day on 21 December. However, most modern liturgical calendars (including the [[Common Worship]] calendar of the Church of England) prefer 3 July, Thomas is [[Calendar of saints (Church of England)|remembered]] in the [[Church of England]] with a [[Festival (Anglicanism)|Festival]].<ref>{{Cite web|title=The Calendar|url=https://www.churchofengland.org/prayer-and-worship/worship-texts-and-resources/common-worship/churchs-year/calendar|access-date=2021-03-27|website=The Church of England|language=en|archive-date=9 March 2021|archive-url=https://web.archive.org/web/20210309204842/https://www.churchofengland.org/prayer-and-worship/worship-texts-and-resources/common-worship/churchs-year/calendar|url-status=live}}</ref>
