The gospel is the power of God for salvation and the gathering of God’s people where the Word is rightly preached, the ordinances are rightly observed, and the saints are rightly taught, equipped, and sent out to make disciples is sufficient to accomplish all that God intends. The question is, will we believe God’s message and God’s methodology? Or will we be double-minded men?

Somewhere in seminary I was introduced to The Gospel Blimp (1967), a made-for-television adaptation of Joseph Bayly’s book by the same name (circa 1950s). For those who do not know Joseph Bayly, he was a Christian editor, author, and satirist that would make the brothers at the Babylon Bee proud. And I lead with his classic film, not because it possessed the best acting or cinematography, but because of its important warning: The works man cannot accomplish the works of God. 

More specifically, the book lampoons the way Christians, especially evangelicals, employ all kinds of gimmicks in order to preach the gospel. Yet, such gimmicks, Jesus junk, and revivalist tactics actual deny the power of the gospel and the wisdom of God that they claim to believe.

What is the wisdom of God? What is a demonstration of God’s power? How should we herald God’s truth?

According to Paul the wisdom of God is found in the preaching of the gospel (1 Corinthians 1-2) and the gathering of the church (Ephesians 3). In other words, the most effective ways for evangelism are not the schemes and strategies of men, nor are they the “God showed me” ideas of eager Christians. Instead, God’s strategy is laid down in Scripture. God’s plan is simple: disciples making disciples, by means of the regular preaching of the Word, the sharing of the gospel, prayer, and suffering.

Historically, this approach to limiting ministry to the regular means of grace has been referred to as the regulative principle. The regulative principle of worship affirms the all-sufficient wisdom of God’s Word and seeks to practice only what is commanded in Scripture. By contrast, the normative principle of worship has granted more freedom of expression, whatever Scripture does not forbid is thereby permitted.

Obviously, these are principles for church worship are derived from Scripture; they are not absolute mandates found in Scripture. That said, they provide a helpful rubric for thinking about what we do in church and what we don’t. So to help understand these principles, let me offer a few definitions and then return to the main point—that we should avoid gospel gimmicks and stick to the simple wisdom proclaiming the Word and gathering the people.

The Regulative Principle

In his Dictionary of Theological Terms (377–78), Alan Cairns defines the regulative principle in this way, “The theory of church government and worship that stipulates that not only church doctrine but also church practice, must be based on clear scriptural warrant.” That is his one-sentence definition, and it helps us to see that the regulative principle is one that stands on the whole counsel of God and calls the church to avoid creativity in worship or ministry.

Historically, this is the approach of the Reformed tradition as set out in the Westminster Confession, which Cairns cites as he gives a brief history of the regulative principle

[The regulative principle] is the position laid down in the Westminster Confession of Faith and is the opposite of the normative principle espoused by Lutherans and Anglicans.

In its statement on the Holy Scriptures the Confession says, “The whole counsel of God, concerning all things necessary for his own glory, man’s salvation, faith, and life, is either expressly set down in Scripture, or, by good and necessary consequence may be deduced from Scripture: unto which nothing at any time is to be added, whether by new revelations of the Spirit, or traditions of men. Nevertheless, we acknowledge … that there are some circumstances concerning the worship of God, and government of the Church, common to human actions and societies, which are to be ordered by the light of nature and Christian prudence, according to the general rules of the Word, which are always to be observed” (chap. 1, sec. 6).

In its chapter on “Religious Worship and the Sabbath” the Confession applies these general principles to the particulars of worship and practice: “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” (chap. 21, sec. 1).

These balanced statements avoid the extreme of allowing into the church’s worship and government whatever is not expressly forbidden in the Word and the opposite extreme of demanding that every detail of our practice should have an explicit command of Scripture before it is allowable. Many things—e.g., the time and frequency of church services, the particular order of service in public worship, the length of services and sermons, the taking of minutes in session meetings, etc.—are not given us in Scripture.
