CHAPTER XVIII. In what order the Psalms are to be said
23 Feb. 24 June. 24 Oct.

Vespers are to be sung every day with four Psalms. And let these begin from the hundred and ninth, and go on to the hundred and forty-seventh, omitting those of their number that are set apart for other Hours – that is, from the hundred and seventeenth to the hundred and twenty-seventh, the hundred and thirty-third, and the hundred and forty-second. All the rest are to be said at Vespers. And as there are three Psalms wanting, let those of the aforesaid number which are somewhat long be divided, namely the hundred and thirty-eighth, the hundred and forty-third, and the hundred and forty-fourth. But let the hundred and sixteenth, as it is short, be joined to the hundred and fifteenth. The order of the Psalms at Vespers being thus disposed, let the rest, that is, the lessons, responses, hymns, verses and canticles, be said as already laid down. At Compline the same Psalms are to be repeated every day: namely the fourth, ninetieth, and hundred and thirty-third.

Saint Benedict begins the weekly cycle of Vespers psalms with Psalm 109 on Sunday evening. Psalm 109, a mysterious revelation of Christ as Priest and King, holds a place of choice in our traditional Benedictine cursus of the Psalter.

When Our Lord Jesus Christ looked into the psalms, He saw His own face as in a mirror. “All things must needs be fulfilled, which are written in the law of Moses, and in the prophets, and in the psalms, concerning me” (Luke 24:44). So too, does His Spouse, the Church see the Face of Christ, her Bridegroom, her King, and her Priest in the psalms. Jesus quotes Psalm 109, saying, “David himself, inspired by the Holy Spirit, declared, ‘The Lord said to my Lord, Sit at my right hand, till I put thy enemies under thy feet.’ David himself calls him Lord; so how is he his son?” (Mark 12:36). An allusion to the same Psalm 109 recurs at the very end of Saint Mark’s gospel: “So then the Lord Jesus, after he had spoken to them, was taken up into heaven, and sat down at the right hand of God” (Mark 16:19).

On the morning of Pentecost, Saint Peter, filled with the Holy Ghost, preaches the mystery of the risen and ascended Christ saying, “David did not ascend into the heavens, but he himself says, ‘The Lord said to my Lord, Sit at my right hand, till I make thy enemies a stool for thy feet.’ Let all the house of Israel therefore know assuredly that God has made him both Lord and Christ, this Jesus whom you crucified” (Acts 2:34-36). Psalm 109 is the ground of some of the most important Christological doctrines of the New Testament. Saint Paul alludes to it in Romans (8:34), Ephesians (1:20), and Colossians (3:1). We discover Psalm 109 four times in the Letter to the Hebrews.

From the time of the Apostles, Psalm 109 has been a mirror wherein the Church contemplates the mystery of Christ in His suffering and triumph. The Church, in her sacred liturgy, holds fast to the understanding of Psalm 109 that Our Lord passed on to the Apostles. Deep in her collective memory the Church cherishes the incomparable seventh mode antiphon that, for centuries, has opened the evening sacrifice of praise on Sunday: Dixit Dominus Domino meo: Dede a dextris meis (Psalm 109:1). She hears the voice of Christ repeating for her what the Father said to Him on the day of resurrection: “Sit at my right” (Psalm 109:1).

The medieval monastic Psalters place a Christological title at the beginning of each psalm. These old titles of the psalms—there are many series of them—say, in some way, “Here is the mystery of Christ in this psalm. Contemplate His Face as in a mirror, and hear in this psalm the sound of His voice”. One ancient series of psalm titles has this for Psalm 109: “Of the divinity, the humanity, the kingship, and the priesthood of Christ”.

Going through the psalm, verse by verse, we see in verse 1 Christ enthroned at the right hand of the Father, an image that recurs in the Gloria of the Mass and in the Te Deum. In verse 3 we hear the voice of the Father saying, “From the womb before the daystar I begot thee” (Psalm 109:3). Verse 4 is the declaration of Christ’s eternal priesthood: “Thou art a priest forever according to the order of Melchisedech” (Psalm 109:4). Verses 5 and 6 describe the triumph of Christ over the powers of death. In the last verse of the psalm the whole mystery of Christ’s passion, death, and resurrection is summed up: “He shall drink of the torrent in the way—the torrent of His bitter sufferings—therefore He shall lift up his head—in the glory of the resurrection and ascension” (Psalm 109:7).

How does all of this relate to our life? When we begin to see the Face of Christ in the psalms as in a mirror, we can begin to relate them to our own monastic journey as well. We are all of us called, in some way, to “drink of the torrent [of humiliation and suffering] in the way” (Psalm 109:7). At the same time, our indefectible hope is that, like Christ and with him, we too shall “lift up our heads”. All that the Father said to Christ is also spoken to us. All that was accomplished in Christ our Head must fulfilled in his Body and in each of his members. And so the psalms of David, the psalms of Christ, mark the rhythm of our life in Christ, hour by hour, day by day, and week after week.
