Today is the Feast of the Most Holy Trinity. It is also the first Sunday after Pentecost. The feast is now a Double of the First Class having been raised to that rank in the reforms of 1911-13. Before that it was a Double of the Second Class and before that a double. Its origins appear to be as a local feast that originated in Liege in the tenth century and its celebration spreading in northern France and England. The Franciscan John Peckham revised the texts in the thirteenth century. In many local rites (and in the Dominican rite) Sundays were counted after Trinity rather than Pentecost.
The feast began yesterday with first Vespers on Saturday marking the beginning of the Summer (Aestiva) volume of the Breviarium Romanum. The Office is proper with the antiphons Gloria tibi Trinitas etc sung with Pss. 101, 110, 111, 112 and 116. The chapter, O altitudo, and hymn, Jam sol recedit, will be used at Vespers on Saturdays for all the Sundays after Pentecost. The antiphon on the Magnificat, Gratias tibi, Deus etc, and the collect are proper. A commemoration was sung of the first Sunday after Pentecost. After Vespers the antiphon Salve Regina is sung for the first time this year.
At Mattins there are three nocturns. The invitatory is proper, Deum verum, unum in Trinitate, et Trinitatm in Unitate, Venite adoremus. The antiphons and responsories are proper. In the first nocturn the lessons are taken from the sixth chapter of the Prophet Isaiah. In the second nocturn they are taken from the Book of Bishop Fulgentius on faith and in the third nocturn from a homily of St. Gregory Nazianzen The ninth lesson is of the first Sunday after Pentecost. At Lauds a commemoration of the Sunday is sung.
At Prime the festal psalms are sung (53, 118i & 118ii). The Creed of St. Athanasius, Quicumque, is sung after the last stanza of Ps. 118. Prior to Pius X Quicumque was sung on all Sundays throughout the year when the Office was Dominical. In many Uses, e.g. Sarum, it was sung on many more days in the year too.
Mass is sung after Terce. Before Mass at the sprinkling of lustral water the antiphon Asperges me returns. The Mass is proper, Benedicta sit. The Gloria is sung, the second collect is of the Sunday, the Credo is sung, the preface that of the Most Holy Trinity (used for all Sundays not having a proper preface after 1759), and the last Gospel of the Sunday.
In second Vespers a commemoration of the following feast of St. Angela Mericiae and of the first Sunday after Pentecost is sung.
In the 'liturgical books of 1962' there is no commemoration of the first Sunday after Pentecost at Vespers, Mattins or Lauds. The eighth lesson is split into two to make a ninth lesson for the feast. At Prime Quicumque is sung only on this Sunday in the 1962 rite. At Mass there is no commemoration of the Sunday, and no proper last Gospel.
