2. One virtue can have but one act; for habits are differentiated

according to their acts. But religion has many acts, e.g., to worship, to serve, to make vows, to pray, to make sacrifices, and many other similar things. Consequently religion is not one virtue.

But by one and the same act does man serve God and worship Him; for worship is referred to God's excellence, to which is due reverence: service regards man's subjection, for by reason of his condition he is bound to show reverence to God. And under these two heads are comprised all the acts which are attributed to religion; for by them all man makes protestation of the Divine excellence and of his subjection of himself to God, either by offering Him something, or, again, by taking upon himself something Divine.
