Palm Sunday is a privileged semi-double Sunday of the first class and the sixth, and last, Sunday in Lent. No feast can take its place. In the Roman rite Palm Sunday, in its authentic form, is a truly magnificent day with the splendid solemn blessing of Palms and Procession before the principle Mass. The liturgical colour, throughout, is violet. This year the feast of the Annunciation is transferred to Monday, 9th April.
The Office began, as usual in Lent, with Vespers yesterday morning. Vespers were sung with the antiphons and psalms of Saturday. The chapter, from Philippians, Fratres: Hoc enim senite, was proper to the Sunday. The Office hymm was Vexilla regis. The antiphon on the Magnificat, Pater juste, and collect were proper to Palm Sunday. After the collect of the Sunday a commemoration of the preceding Office of St. Gabriel the Archangel was sung. At Compline, sung at the usual time, the Dominical preces were omitted.
At Mattins there are the usual three nocturns. The antiphons and psalms at all the nocturns are those appointed for Sundays. In the first nocturn the lessons are from the book of Jeremiah the Prophet. In the second nocturn the lessons are a sermon of St. Leo the Great and in the third a homily of St. Ambrose. The Te Deum is not sung but a ninth responsory, Circumdederunt me viri mendaces etc., is sung in its place. At Lauds the antiphons are proper, Dominus Deus etc., to Palm Sunday and the second scheme of Psalms is sung (50, 117, 62, Benedictus es, 148). The chapter is proper to the Sunday and the Office hymn is Lustra sex.
At Prime and the Hours the antiphons are proper to the Sunday, Pueri Hebraeorum etc. At Prime psalms 92, 99 (displaced from Lauds) and the first two divisi of Ps. 118 are sung. The Dominical preces are sung and the short lesson is Faciem meam. At Terce the antiphon is Pueri Hebraeorum vestimenta which again will be heard shortly afterwards at the distribution of Palms.
After Terce, as usual, the Asperges ceremony takes place before the principal Mass. The deacon and subdeacon wear violet folded chasubles. Being in Passiontide the Lesser Doxology is omitted after the verse of the Miserere. After the Asperges the celebrant and ministers proceed to the Epistle corner and begin the solemn blessing of Palms whilst the choir sing the antiphon Hosanna fili David, O Rex Israel etc. The rubrics direct that the Palms are to be blessed at the Epistle side of the altar.
The blessing begins with the celebrant reading an antiphon Hosanna Filio David followed by a collect Deus, quim diligere and then the reading of an Epistle and Gospel. The normal ceremonies of High Mass are followed. The subdeacon removes his folded chasuble to sing the Epistle taken from the Book of Exodus. Following the Epistle two texts are given, Collegerunt pontifices and In monte Oliveti (the latter will appear again as a responsory during the Triduum) to be sung as a 'gradual', both may be sung.
Following the Gospel the deacon resumes his folded chasuble and the collect Auge fidem is sung followed by a preface, Sanctus and four further collects Deus, qui dispersa, Deus, qui miro, Deus, qui per olivae and Benedic quaesumus. The presence of a preface is indicative of the solemn blessing (c.f. the great blessing of waters at Epiphany). The collect Deus, qui miro is a didactic masterpiece. Readers will note the strong correlation between the text of the collect and of the second lesson of Mattins for the Saturday before Palm Sunday from St. Augustine:
O God, who, by the wonderful order of Thy disposition, hast been pleased to manifest the dispensation of our salvation even from things insensible: grant, we beseech Thee, that the devout hearts of Thy faithful may understand to their benefit what is mystically signified by the fact that on this day the multitude, taught by a heavenly illumination, went forth to meet their Redeemer, and strewed branches of palms and olive at His feet. The branches of palms, therefore, represent His triumphs over the prince of death; and the branches of olive proclaim, in a manner, the coming of a spiritual unction. For that pious multitude understood that these things were then prefigured; that our Redeemer, compassionating human miseries, was about to fight with the prince of death for the life of the whole world, and, by dying, to triumph. For which cause they dutifully ministered such things as signified in Him the triumphs of victory and the richness of mercy. And we also, with full faith, retaining this as done and signified, humbly beseech Thee, O holy Lord, Father almighty, everlasting God, through the same Jesus Christ our Lord, that in Him and through Him, whose members Thou hast been pleased to make us, we may become victorious over the empire of death, and may deserve to be partakers of His glorious Resurrection.
The celebrant then puts on incense and blesses it. The Palms are then aspersed with lustral water, the celebrant saying in a low voice Asperges me etc, and then censed. Another collect, Deus, qui Filium is then sung. The celebrant then receives his Palm from the senior canon present. If no other priest is present the celebrant kneels and takes the Palm from the of the altar, kisses it then passes it to the subdeacon who places it again on the mensa. The celebrant then gives Palms to the deacon and subdeacon and other ministers and then the people. The Palm is kissed first and then the celebrant's hand. During the distribution the antiphons Pueri Hebraeorum and Pueri Hebraeorum vestimenta are sung. After the distribution the celebrant and ministers go back to the altar, bow to the Cross and then go to the Epistle corner where the celebrant's hands are washed. Then, at the missal, he sings the collect Omnipotens sempiterne.
The celebrant's hands are washed after the distribution of Palms whilst the, veiled, Processional Cross is decorated with some of the blessed Palms. A Procession is then formed, led by the thurifer, followed by the subdeacon (of the Mass, not this day an additional subdeacon) bearing the Processional Cross. The deacon sings Procedamus in pace and the following antiphons are sung during the Procession Cum appropinquaret, Cum audisset, Ante sex dies, Occurrunt turbae, Cum angelis et pueris and Turba multa.
Ideally the Procession goes outside and around the church but circumstances may dictate the Procession must simply go around the aisles of the church. Towards he end of the Procession cantors re-enter the church and the door is closed. The beautiful hymn of Theodolph Gloria, laus, et honor is then sung in alternation between the cantors inside the church and everyone else outside. At the end of the hymn the subdeacon, or Crucifer when there are no ministers, strikes the church door three times with the foot of the Processional Cross and the party re-enters the church to the singing of Ingrediente Domino.
The celebrant removes his cope and dons his chasuble. The preparatory prayers are said but the psalm Judica me is omitted being in Passiontide. The introit is Domine, ne longe etc. There is no Gloria. Psalm 21 is sung in its entirety as a Tract. The major difference from any other Sunday is singing of the Passion according to St. Matthew by three additional deacons of the Passion. The text of the Passion is Matthew 26: 1-75; 27: 1-66. After the singing of the Passion the last part, Altera autem die...lapidem cum custodibus, is sung with the ceremonies of a Gospel by the deacon of the Mass (having removed his folded chasuble etc) to a most haunting tone.
The choir and people hold their Palms during the singing of the Passion. The Creed is sung, the preface is of the Cross and the dismissal is Benedicamus Domino, sung by the deacon facing the celebrant and altar.
Sext and None again have proper antiphons, Tibi revelavi etc and Invocabo etc respectively. At Vespers the antiphons and psalms of Sunday are sung. The chapter is Hoc enim senite and the Office hymn is Vexilla regis, both as at Vespers yesterday. At Compline the Dominical preces are sung.
In the 'liturgical books of 1962' Palm Sunday has been radically given a 'makeover' to the extent that the official title of the day has even been changed to 'Second Sunday of the Passion or Palm Sunday'. For those interested in the depressing catalogue of destruction an earlier post here gives the details. The image below shows a typical blessing of Palms in the reformed rite, actually following its rubrics, with the palms on a table facing the people.
