Prayer of Praise
Praise, though similar to blessing and thanksgiving, is a distinct type of prayer. It is a prayer “which recognizes most immediately that God is God. It lauds God for his own sake and gives him glory, quite beyond what he does, but simply because HE IS” (2639).
The Catechism explains, “Like the inspired writers of the New Testament, the first Christian communities read the Book of Psalms in a new way, singing in it the mystery of Christ. In the newness of the Spirit, they also composed hymns and canticles in the light of the unheard-of event that God accomplished in his Son” (2641).
This prayer is also found in the book of Revelation where, “The prophets and the saints, all those who were slain on earth for their witness to Jesus, the vast throng of those who, having come through the great tribulation, have gone before us into the Kingdom, all sing the praise and glory of him who sits on the throne, and of the Lamb” (2642).
It is a prayer that simply praises God because he is God, not in reference to any specific benefit or favor obtained. The celebration of the Eucharist is often called a “sacrifice of praise.”
