March 15th - Dominica in Palmis - Palm Sunday

(A 15th century Russian Icon of the Entry of the Lord into Jerusalem from Wikipedia

Palm Sunday is a privileged semi-double Sunday. It is the sixth Sunday in Lent and the beginning of Great or Holy Week.

At Vespers, yesterday morning, the antiphons and psalms of Saturday (Pss.143, 144, 145, 146 & 147) were sung. The chapter was proper to the Sunday, the Office hymn Vexilla regis prodeunt. The antiphon on the Magnificat and collect were proper to the Sunday. At Compline the Dominical preces were omitted.

At Mattins, as last week and daily until the Triduum, the invitatory is Hodie, si vocem Domini audieritis, Nolite obdurare corda vestra from Ps. 94 and a special rubric indicates the omission of that verse in the psalm. The hymn is Pange, lingua. The antiphons given in the Psalter for Sundays are used. As usual Mattins has three nocturns and nine lessons. In the first nocturn psalms 1, 2, 3, 6, 7, 8, 9, 10, 11, 12, 13 & 14 are sung. The lessons in the first nocturn are from the book of Jeremiah. These are the same, as are their responsories, as those found in 'modern' versions of the Breviary. In the second nocturn psalms 15, 16 and 17 are sung and the lessons are from a sermon on the Passion by St. Leo. The fifth lesson begins with the words Qui ut humanum genus and incorportates what is now the sixth lesson from Fefellit ergo illum.. until famulatae sunt Redemptori. The sixth lesson, Quod ergo...justitiae esse propositum is not found in the 'modern' Breviary. In the third nocturn psalms 18, 19 & 20 are sung and the lessons are a homily of St. Ambrose, their arrangement is slightly different to that found in the modern books. The Te Deum is omitted as on other Lenten Sundays and a ninth responsory, Circumderunt me viri mendaces..., sung in its place.

At Lauds the antiphons are proper to Palm Sunday, Dominus Deusetc, and sung with Pss. 50, 117, 62-66, Benedicite, 148-149-150. The hymn is Lustra sex. The versicle after the hymn Eripe me, chapter, antiphon on the Benedictus and collect are proper to the Sunday.

At Prime the order of psalmody is Pss. 53, 92, 118(i), 118(ii) and Quicumque, the 'Athanasian' Creed. The Dominical preces are sung. At all the Hours the antiphons and chapters are proper.

The Asperges, Blessing and Procession of Palms and Mass takes place after Terce. The rite is the same as existed until 1956 which may be read about here.

Vespers are of the Sunday. At Compline the Dominical preces are sung. The additional Offices of the Little Office of the BVM, the Office of the Dead, the Gradual Psalms and the Penitential Psalms and Litany are omitted in Great Week.
