The Regulative Principle of Worship

Dear brothers and sisters,

Grace and peace to you from God our Father and the Lord Jesus Christ. I write to you concerning how God is to be worshipped, a matter that has divided Protestant churches for centuries and that many in our day have forgotten to ask. Should the Church offer to God only what He has commanded in His Word, or may she add whatever seems fitting so long as Scripture does not forbid it? The answer we give will shape our liturgy, our music, and our piety. It is the difference between the regulative principle of worship and the normative principle. I believe the former is the teaching of Scripture and the historic Reformed confession.

What the Regulative Principle Is

The regulative principle of worship holds that God alone may prescribe how He is to be worshipped. Whatever is not commanded in Scripture for the worship of God is forbidden. We may not invent rites, ceremonies, or elements of worship and then offer them to God in the name of piety. He has told us what He requires. Our part is to obey.

This principle is sometimes summed up in the phrase “what is not commanded is forbidden” in worship. The contrast is the normative principle: “what is not forbidden is permitted.” Under the normative principle, a church may introduce any practice into worship that Scripture does not explicitly prohibit. Under the regulative principle, a church may include only what Scripture explicitly commands or necessarily implies. The Reformed confessions and the best Reformed divines have consistently held the regulative principle. The Westminster Confession of Faith states it plainly:

“The acceptable way of worshipping the true God is instituted by Himself, and so limited by His own revealed will, that He may not be worshipped according to the imaginations and devices of men, or the suggestions of Satan, under any visible representation, or any other way not prescribed in the Holy Scripture.”Westminster Confession of Faith 21.1

Calvin put it with characteristic clarity: we may not worship God except in the manner He has prescribed. He alone is entitled to prescribe.

“We may not worship God except in the manner he has prescribed.”John Calvin, Institutes of the Christian Religion 1.11.4

God is worshipped in the way He has instituted. We are not at liberty to add or subtract. That is the regulative principle.

The Foundation in Scripture

Moses, in Deuteronomy, repeatedly warns Israel not to worship the Lord in the way the nations worship their gods. They must destroy the high places and the altars of the nations. They must bring their offerings to the place the Lord chooses. And they must do only what He commands:

“Everything that I command you, you shall be careful to do. You shall not add to it or take from it.”Deuteronomy 12:32

This verse is often cited in support of the regulative principle. In the context of worship and the place of sacrifice, God forbids adding to or taking from what He has commanded. The same logic appears when Nadab and Abihu offered unauthorized fire before the Lord and were consumed (Leviticus 10:1–2). They did a thing the Lord had not commanded. The Lord had specified how the fire was to be kindled and what was to be offered. They presumed to improve upon His instructions. The result was judgment. We are not free to worship God in ways we devise. We are free only to worship Him in the ways He has revealed. Calvin, commenting on the rule that separates pure worship from corrupt, wrote:

“The rule which distinguishes between pure and vitiated worship is of universal application, in order that we may not adopt any device which seems fit to ourselves, but look to the injunctions of him who alone is entitled to prescribe.”John Calvin, Institutes of the Christian Religion 4.10.8

Our Lord Jesus Christ applied this standard to the worship of His day. He condemned the Pharisees for replacing the commandment of God with the traditions of men. When they asked why His disciples did not wash their hands according to the tradition of the elders, He answered:

“In vain do they worship me, teaching as doctrines the commandments of men.”Matthew 15:9

Vain worship is worship shaped by human commandment rather than divine. The Apostle Paul warns against “will-worship,” that is, worship that proceeds from our own will rather than from the Word (Colossians 2:23). Such worship has an appearance of wisdom but is of no value. The regulative principle is not a Reformed innovation. It is the consistent teaching of the law, the prophets, Christ, and the apostles.

What God Has Commanded

If we may worship only as God has commanded, we must ask what He has commanded. The New Testament shows the apostolic church gathering for the reading and preaching of the Word, for prayer, for the singing of psalms and spiritual songs, for the administration of the sacraments of baptism and the Lord’s Supper, and for the collection for the saints. The elements of worship are not left to our imagination. They are given. Preaching, prayer, singing, the sacraments, and the offering are all either explicitly instituted or clearly implied in Scripture. The regulative principle does not empty worship of richness. It fills it with what God has appointed and protects it from what He has not.

Some object that the regulative principle leads to a bare, cold, or minimal worship. The opposite is true. When we confine ourselves to what God has commanded, we are not left with nothing. We are left with the reading and preaching of the Word, which is the chief means of grace. We are left with prayer, in which we pour out our hearts to God. We are left with the singing of His praise, in psalms and hymns that reflect His Word. We are left with baptism and the Lord’s Supper, the visible signs and seals of the covenant. We are left with the offering of our substance for the work of the Church. These are not small things. They are the very means by which God has promised to meet with His people and build them up in the faith. To add to them is not to enrich worship but to obscure it. To add drama, dance, or entertainment, or to introduce rites and ceremonies that Scripture does not prescribe, is to suggest that what God has given is insufficient. It is to worship according to the imaginations and devices of men.

Spirit and Truth

Our Lord told the woman at the well that the hour was coming when true worshippers would worship the Father in spirit and truth (John 4:23–24). God is spirit, and those who worship Him must worship in spirit and truth. The regulative principle serves that end. Worship in truth is worship according to the Word of God, which is truth. Worship in spirit is worship that proceeds from a heart renewed by the Spirit and that relies on the Spirit’s help. Neither spirit nor truth permits us to invent ways of worshipping God that He has not commanded. The Spirit inspired the Scripture. He does not lead us to contradict it or to add to it in the worship of God.

I do not write to lay a burden on you but to remind you of the freedom we have when we worship within the bounds God has set. We are not left to guess what pleases Him. He has told us. We are not left to impress Him with our creativity. He has given us the elements of worship that honour Him and that He uses for our good. Let us hold fast to the regulative principle. Let our worship be ordered by the Word alone.
