December 22nd - St. Thomas the Apostle

The feast of St. Thomas the Apostle is of double rite and its liturgical colour is red. The feast is transferred to today as it fell on the fourth Sunday of Advent. According to tradition St. Thomas preached the Gospel in Asia and the Indian sub-continent. He is believed to have founded, inter alia, the St. Thomas Christians on the West coast of India, one of several groups using the East-Syrian family of liturgies.

At Vespers yesterday afternoon the antiphons Hoc est praeceptum meum etc were sung with psalms 109, 110, 111, 112 & 116. The Office hymn was Exsultet caelum laudibus. The antiphon on the Magnificat was proper to the feast, Quia vidisti me etc. After the collect of the feast the Sunday was commemorated with the Great 'O' Antiphon appointed for the 21sth December, O Oriens. At Compline the preces were omitted.

At Mattins the invitatory is Regem Apostolorum Dominum, Venite adoremus and the Office hymn is Aeterna Christi munera. In the first nocturn the antiphons In omnem terram etc are sung with psalms 18, 33 & 44. The lessons are Sic nos existimet homo from St. Paul's First Epistle to the Corinthians. The third lesson is considerably longer than that found in the post-Clementine editions of the Breviary continuing Rogo ergo vos imatores mei (...) et spiritu, i.e, vv. 16-21. In the second nocturn the antiphons Principes populorum etc are sung with psalms 46, 60 & 63. The fourth lesson, proper to the feast, is the same as in modern editions of the Breviary. The fifth and sixth lessons are from a homily of St. Gregory (from the Common) and are longer than those found in the modern editions. In the third nocturn the antiphons Exaltabuntur etc are sung with psalms 74, 96 & 98. The homily on St. John's Gospel is from St. Gregory. These are the same as in the post-Clementine editions of the Breviary. The Te Deum is sung.

At Lauds the antiphons Hoc est praeceptum meum etc are sung with the Dominical psalms (92, 99, 62-66, Benedicite & 148-149-150). The antiphon on the Benedictus, Quia vidisti me, Thoma, credidisti: beati, qui non viderunt, et crediderunt, alleluia, is proper to the feast and refers to the incident recorded in the Gospel of St. John about St. Thomas' doubt in the Risen LORD. A commemoration is then made of the Advent feria, the antiphon on the Benedictus being Dicit Dominus etc for the Monday in the fourth week of Advent.

The antiphons sung at Lauds are sung in due order at the Horae Minores. At Prime the festal psalms (53, 118i & 118ii) are sung and the lectio brevis is Ibant Apostoli.
