Particular elements of worship are highlighted: reading the Bible (1 Tim. 4:13); preaching the Bible (2 Tim. 4:2); singing the Bible (Eph. 5:19; Col. 3:16) — the Psalms as well as Scripture songs that reflect the development of redemptive history in the birth-life-death-resurrection- ascension of Jesus; praying the Bible — the Father’s house is “a house of prayer” (Matt. 21:13); and seeing the Bible in the two sacraments of the church, baptism and the Lord’s Supper (Matt. 28:19; Acts 2:38–39; 1 Cor. 11:23–26; Col. 2:11–12). In addition, occasional elements such as oaths, vows, solemn fasts and thanksgivings have also been recognized and highlighted (see Westminster Confession of Faith 21:5).
Put simply, the regulative principle of worship states that the corporate worship of God is to be founded upon specific directions of Scripture. On the surface, it is difficult to see why anyone who values the authority of Scripture would find such a principle objectionable. Is not the whole of life itself to be lived according to the rule of Scripture? This is a principle dear to the hearts of all who call themselves biblical Christians. To suggest otherwise is to open the door to antinomianism and license.
But things are rarely so simple. After all, the Bible does not tell me whether I may or may not listen with profit to a Mahler symphony, find stamp-collecting rewarding, or enjoy ferretbreeding as a useful occupation even though there are well-meaning but misguided Bible-believing Christians who assert with dogmatic confidence that any or all of these violate God’s will. Knowing God’s will in any circumstance is an important function of every Christian’s life, and fundamental to knowing it is a willingness to submit to Scripture as God’s authoritative Word for all ages and circumstances. But what exactly does biblical authority mean in such circumstances?
Well, Scripture lays down certain specific requirements: for example, we are to worship with God’s people on the Lord’s Day, and we should engage in useful work and earn our daily bread. In addition, covering every possible circumstance, Scripture lays down a general principle: “present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect” (Rom. 12:1–2). Clearly, all of life is to be regulated by Scripture, whether by express commandment or prohibition or by general principle. There is therefore, in one sense, a regulative principle for all of life. In everything we do, and in some form or another, we are to be obedient to Scripture.
However, the Reformers (John Calvin especially) and the Westminster Divines (as representative of seventeenth-century puritanism) viewed the matter of corporate worship differently. In this instance, a general principle of obedience to Scripture is insufficient; there must be (and is) a specific prescription governing how God is to be worshiped corporately. In the public worship of God, specific requirements are made, and we are not free either to ignore them or to add to them. Typical by way of formulation are the words of Calvin: “God disapproves of all modes of worship not expressly sanctioned by his Word” (“The Necessity of Reforming the Church”); and the Second London Baptist Confession of 1689: “The acceptable way of worshiping the true God, is instituted by himself, and so limited by his own revealed will, that he may not be worshiped according to the imagination and devices of men, nor the suggestions of Satan, under any visible representations, or any other way not prescribed in the Holy Scriptures” (22.1).
Where does the Bible teach this? In more places than is commonly imagined, including the constant stipulation of the book of Exodus with respect to the building of the tabernacle that everything be done “after the pattern . . . shown you” (Ex. 25:40); the judgment pronounced upon Cain’s offering, suggestive as it is that his offering (or his heart) was deficient according to God’s requirement (Gen. 4:3–8).
