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

The Introït is excerpted from the Epistle of St. Paul to the Philippians (4:4). The Lord is nigh, and this announcement fills the heart with joy, a joy, moreover, quite different from that to which the world gives itself, because it is the fruit of the interior peace that the Holy Ghost communicates to the soul when it remains faithful to the holy will of God. A versicle from Psalm 84 follows the antiphon of the Introit; it is characteristically the canticle of deliverance.

The Gradual is taken from Psalm 79, which we have already encountered in the Introit of the preceding Sunday. He who immutably reigns over the Cherubim in glory, and who directs the destiny of men, is going to come with all His might to combat the ancient enemy.

The verse of the Alleluia belongs to the same psalm.

Like the Introït, the Offertory is taken from Psalm 84. The coming of Jesus on earth is the blessing promised by God to Abraham: it is the deliverance from slavery, it is the remission of sin.

During the Communion a last invitation to the fainthearted resounds: Fear not; it is no longer a prophet, a lawgiver, a scribe, as heretofore in the Old Testament, but God Himself who is coming to save us (Is. 35:4).
