Saint Thomas, Apostle & the FIFTH ANTIPHON: O Oriens (21 December) ~ Dom Prosper Guéranger

About this sermon

On December 21, the Holy Church pauses in her Advent expectation to honor Saint Thomas the Apostle, whose glorious martyrdom sanctified this day, while also proclaiming the Fifth Great O Antiphon: O Oriens. In today’s sacred office, the Church speaks these solemn words: “Fear not, for on the fifth day our Lord will come to you.” This meditation draws from the traditional Roman Office, ancient Mozarabic prayers, and Greek Church hymns, revealing how Saint Thomas—once marked by doubt—became a powerful defender of faith, humility, and belief in the unseen God who comes silently as a Child in Bethlehem. Saint Thomas is presented as the Apostle uniquely suited to guide the faithful toward Christmas, helping us believe without seeing, to recognize the King of Nations wrapped not in glory, but in swaddling clothes.
