Summary of comments of this office by Dom Schuster, in his work L'année liturgique.

The Introït is taken from Psalm 65, which is a hymn of triumph: "Shout with joy to God, all the earth; sing ye a psalm to His name; give glory to His praise." How splendid are the words of the Catholic liturgy, but, of course, we must not be content with words alone, as Isaias reproached the Jews for doing. Rather it is the works of our life that must reflect the glory and the holiness of the risen Christ.

The versicle of the Alleluia is taken from Psalm 110, which is one of the songs of Easter. The Lord has redeemed His people, which now belongs to Him by the double claim of creation and redemption.

In the versicle preceding the Gospel, the great law of the kingdom of grace is recalled, the necessity of the cross.

In the antiphon ad offerendum (Ps. 145) the soul is invited to praise the Lord in the new life of the resurrection to which He has raised us, an everlasting life which knows not death. The verse relates especially to Christ, in whose life we participate thanks to the sacraments.

In the antiphon that is sung during holy Communion and which is taken from today's Gospel, the fidelity of Jesus to His promise is highlighted.
