Deuteronomy 12:31

31.Thou shalt not do so. From these words we may gather what it is not to make to one’s self the gods of others, viz., to bid farewell to all the inventions of men, and to pay attention to this one thing — what God commands. For why does God desire to be worshipped by His elect people, otherwise than the nations were in the habit of serving their gods, except because there ought to be a notable distinction, so that religion may not be confused? And surely unless men cleave to God’s word, so as resolutely to determine that nothing else is permitted to them except what is there taught, they will not only be vacillating, but. they will receive indiscriminately whatever comes in their way. We must then hold fast to this, “Thou shalt not do so;” and our minds must be restrained by this curb, lest any superstition which may defile the service of God should insinuate or establish itself. He adds, that God not only repudiates these strange worships, but even abominates them; and in order to impress this the more, he adduces one form of superstition, in which its absurdity was unusually manifest; for it is a foul barbarity that innocent children should be burnt by their parents.
