The Introit of the Missa pro sponsis is one of my favourite Gregorian chants, perhaps since it made quite the impression on me on our wedding day (when I walked into the church the choir was rehearsing it, and the acoustics of the place really hit home).
Deus Israel conjungat vos, et ipse sit vobiscum, qui misertus est duobus unicis: et nunc, Domine, fac eos plenius benedicere te. Ps. Beati omnes qui timent Dominum: qui ambulant in viis ejus.
Unfortunately, I tend to glance over the psalm verse that goes with the Introit at Mass, paying more attention to the opening verse. Only very recently, then, did it dawn on me that I know the psalm from which the verse of this particular Introit was taken: I encounter it several times a week when praying None according to the Monastic Diurnal. The Psalm in question is Psalm 127, Beati omnes. This Psalm figures in a few of the Propers of the nuptial votive Mass and can be found in quite a few other uses’ and rites’ nuptial votive Mass: the Bragan use is very similar to the Roman, and as such the Psalm verse appears in the same places; a 16th century Ambrosian sacramentary shows the entire Psalm being said during the nuptial blessing, while the missal has some Propers taken from it; the Byzantine rite also has recourse to Psalm 127.
What is this Psalm then? What does it have to say about Matrimony that it should find its way into so many matrimonial rites? While the imagery about the married life is pretty straightforward, if you’ll permit me, I’d like to offer a Christological reflection.
 Beati omnes qui timent Dominum, qui ambulant in viis ejus.
 Labores manuum tuarum quia manducabis, beatus es, et bene tibi erit.
 Uxor tua sicut vitis abundans, in lateribus domus tuae; filii tui sicut novellae olivarum in circuitu mensae tuae.
 Ecce sic benedicetur homo qui timet Dominum.
 Benedicat tibi Dominus ex Sion, et videas bona Jerusalem omnibus diebus vitae tuae;
 et videas filios filiorum tuorum, pacem super Israel.
 The bridegroom in this Psalm is Our Lord Jesus Christ, the Bridegroom. He is the one that is Blessed, the Holy One; He is the one who not only walks in the ways of the Lord, but is the Way.
 To be content to eat the labours of one’s hands means that the fruit of one’s labours are good. This signifies that all that Christ does is good. Christ himself said that His food is to do the will of His Father.
 Because the Chuch is the Mystical Body of Christ she can be said to be the fruitful vine as well, as her Bridegroom is the Vine. She is fruitful because she abides in Him. The Church is Our Lord’s spouse, having been born of His side, just as Eve was taken from Adam’s, while both slept. And just as a vine can only grow having support, so the Church grows from the life-giving wound on His side from which she was born. The fruit of the vine is wine, which is His Blood, His Life, and that is which the Church mediates to all men. We adopted sons and daughters, though we are part of the Bride, are mystically the sons and daughters of the Church as well; we are the fruit of the love between the Bridegroom and His beloved. We are as young olive trees, that is, we are to give fruit which will become oil – if we be fruitful, then we will become conduits for the Lord’s grace. The table is a reference to that of the wedding feast of the Lamb, where all who are fruitful will gather around. We see here a reference to a garden – we are reminded of Eden. Christ is the New Adam, and just as the Old before the Fall, His is to guard and till it, so that it be fruitful and multiply.
[5,6] The Lord blesses Him from Sion, that is, from the most Holy of Holies, from the sanctuary not made by human hands. Christ is in the Father, and the Father in Him, and so these He receives all the blessings which eye has not seen, nor ear heard, but which are stored up for those who love Him. He is the Beloved, Only-Begotten Son. He shall see the good of the Jerusalem, that is, the heavenly Jerusalem, all the days of His life because Death has no dominion over Him; His children’s children are the multitude of the saints, which are with Him in this heavenly Jerusalem.
Linking this back to Ephesians 5 (specifically, the pericope which has had such an important impact on our understanding of Matrimony), what are we as a couple supposed to take away from the Psalm? As a husband (and at the moment the only bread-winner for the household), I have to provide for my family while walking the Lord’s ways. I may not being doing the job I’d love to, or even the one I studied for, but I have to do His will where I am now, in my concrete situation. The daily bread I earn must be gotten honestly, through honest work, no matter how “below me” I might at times be tempted to think it is (and it is during those times that the words of the Rule on humility come to mind, about accepting whatever task is set before one). To do what is right, to stay the straight and narrow, when all around one sees corners being cut, is not something within one’s own power. How many times do I fall because I think I can do it on my own? And yet, in accepting what is, in eating the sweat of the brow, a certain peace is to be found. My spouse is to be at my side, to find support in me, to grow in holiness, and in growing to help support myself as well. Our love is to be a fruitful one, open to life; children are to be welcome always. Though they be “ours”, in truth we are only their stewards; ultimately, they belong to God. We are to till and guard them, that they may grow and bear fruit. The most important part of that is passing on the Faith to them. We are the olive trees as well, and as olives are pressed to give healing chrism, so through our daily trails, we hope to be channels of Our Lord’s grace to them, so that they in turn may be to others. We try to conform to one another, to love each other more perfectly, so that we too may one day, when we have reached the end of this time of trial, by God’s grace, may be introduced into the heavenly tabernacle; we try to love eachother so that we may find Christ in one another, and that others may find the love of Christ for His Church in us.
