A Reformed church will offer a clear difference in worship. The reason is our doctrine of the Regulative Principle of Worship (RPW). This is a biblical principle that fixes our motivations and activities in corporate worship. This principle comes from the Second Commandment, “that we in no way make any image of God nor worship him in any other way than he has commanded” (Heidelberg Catechism Q & A 96). The RPW is simply the doctrine of sola scriptura (Scripture Alone) applied to corporate worship. The RPW is not a difficult principle to grasp, it simply teaches that the proper way to determine God’s will concerning worship is to study the Bible to determine acts of worship God has commanded for Christians, and do only those acts.
Our posts over the next few weeks will develop this principle biblically, theologically and explain what biblical Reformed worship looks like.
