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

The Introït comes from Psalm 97: "Sing ye to the Lord a new canticle," one like that which Christ intoned by inaugurating His new life of glory and of triumph the day of His resurrection. And even this is not enough: this happy renovation encompasses the whole world which joins in the joy of Jesus.

The versicle of the Alleluia is taken from Psalm 117: "The right hand of the Lord hath wrought strength, the right hand of the Lord hath exalted me." V. "Christ, rising again from the dead, dieth now no more: death shall no more have dominion over Him."

The antiphon of the Offertory with its luxuriant melody, one of the most exquisite masterpieces of the Gregorian art, is the same as that of the second Sunday after the Epiphany. If the whole world were then invited to admire the prodigy of love shown by God to the world in the Incarnation of the Word, how much more, then, must one do so now that the Lord has associated redeemed mankind to grace, to the resurrection, and to the final glorification of Jesus?

The antiphon for the Communion, taken from the Gospel reading of the day, is like a new menace to the world: "When the Paraclete, the Spirit of truth, is come, He will convince the world of sin, and of justice and of judgment."
