A Psalm of Christ sharing our human life with its vicissitudes and troubles—born of Mary, increasing in wisdom and stature, suffering persecution, proclaiming the Gospel, dying, and rising "from the deep of the earth again" (ver. 18). Consequently it is a Psalm of the saintly life in its conformity to Christ,
PSALM lxxii. Deus, indicium
Matt. ii. 1-11
The Church's joy in Christ, as the Son of David and the King of humanity. The peace and justice of His Kingdom are described, its universality and eternity.
PSALM lxxiii. Quam bonus Israel!
A Psalm of the inward struggle and victory of faith. Christ Himself may be heard speaking in it, as He is "the author and finisher of our faith," and in His human soul fought for us the battle of faith. So the Psalm becomes the Church's testimony to the individual believer of that ultimate answer to the trials of faith which is found in union with God through Christ.
PSALM lxxiv. Ut quid, Deus?
A Psalm of the Church, persecuted and despoiled, appealing to the eternal sovereignty of Christ over nature and man, as it has been revealed in all the history of the Church, both under the old covenant and the new.
PSALM lxxv. Confitebimur tibi
