The Regulative Principle:
In Deuteronomy 12:29-32 Moses continues to expound the 2nd Commandment dealing with the right way to worship God. What kind of worship does God accept? We are told that God does not accept worship by idols, but also that the worship that God does accept is that which is obedient to His commands. There are only two sources for worship practices: man and God. True worship comes from God alone. This principle of true worship being defined by God has historically been called the Regulative Principle of Worship.
