RPW

If you stick around Presbyterian circles for a season, you will probably hear us make reference to the Regulative Principle of Worship (RPW) at some point. If I may be anachronistic by less than a century, Martin Bucer defines the principle well in his book, de Regno Christi:

“The first [property of the Kingdom of Christ] is that whatever is done in the churches should pertain to the ministry and contribute to the gaining of men's salvation in such a way that, cleansed from sins and reconciled to God through Christ, they may worship and glorify God in Christ the Lord in all piety and righteousness.

“Whatever does not contribute to this end, and nothing can do so which has not been ordained for this purpose by the Son of God and so commended to us, should be rejected and abolished by those who wish the Kingdom of God restored among them.”
