Calvin defines idolatry: 'Every object of worship which men contrive is a creature of their own imagination.'
John Calvin provides a verse-by-verse exposition of Galatians 6-11, focusing on the doctrine of adoption by the Spirit, the danger of returning to ceremonial observances, and a sharp critique of what he calls 'popery' for denying the Spirit's witness. The commentary contrasts Christian freedom with Jewish bondage and superstitious day-keeping.
