They have never included new uncommanded activities such as those mentioned above. Thus they justify new practices such as drama as a form of preaching and dance as a form of praise. Such teachers have, whether unwittingly or purposefully, returned to the normative principle of worship by adding what Scripture has not specifically prohibited. No amount of protesting to the contrary can change this fact. In summary, the Reformed regulative principle of worship allows only those elements of worship which have been positively instituted and commanded by God in Scripture.
Infant baptism violates the regulative principle of worship.
Thus it is regulated by God, limited by His revealed will, and prescribed by Holy Scripture. This regulation extends to the subjects of baptism. Christ's institution of baptism, in its mode, meaning, and subjects is to be regulated by the Word of God. Yet, as Baptists and Paedobaptists agree, the only subjects of baptism which can be conclusively determined by Scripture are professing disciples. The practice of baptizing babies violates the regulative principle.
