Hebrews 13:14,15

We have not a permanent city in this world, but are like pilgrims or banished men, seeking for our happy country of heaven; but in the mean time must offer to God a sacrifice of praise and thanksgiving, which is done chiefly in the holy sacrifice of the Eucharist, also by confessing his name, and praying to him with our lips and hearts; and by a kind of sacrifice of charity, by doing good to every one, and of communication to others; literally, of communion, or union with our neighbours. (Witham) --- When we read in the psalms, and in the old Scripture, of a sacrifice of praise, we may look upon it as a prophecy of the Christian Eucharist or sacrifice of praise, of which St. Augustine says: "What is a more holy sacrifice of praise, than that which consisteth in thanksgiving, which the faithful offer now in the sacrifice of the Church." (lib. 1. cont. Advers. leg. and proph. chap. xviii.) And again chap. xx. "The Church from the time of the apostles, by an uninterrupted succession of prelates, offers to God in the body of Christ the sacrifice of praise."
