Calvin on Hosea 2:17, on the Papist idolatry
“Let us worship Baalim.” The Papists do the same; when they enter their temples, they immediately turn to the image of Mary or of some saint, and dare not come to God. At the same time they worship God, that is, pretend to worship God, and they call superstition God’s worship.
