The sum is, that the worship of God must be spiritual, in order that it may correspond with His nature. For although Moses only speaks of idolatry, yet there is no doubt but that by synecdoche, as in all the rest of the law, he condemns all fictitious services which men in their ingenuity have invented.

John CalvinWhere God's Spirit does not reign, there is no humility, and men ever swell with inward pride.
