How should the church apply the Regulative Principle?

Sam Waldron explains in this video that churches need to come back to Scripture alone as the regulative principle for the church. 

The worship, government, doctrine, and our understanding of the church all must be governed by the Word of God and the regulative principle. Simply put, if God has not commanded it, it should not occur within the church.

2 Timothy 3:16 (NKJV) – “All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness.”

In the church, my burden would be to say that I think we don't need to come back to the Scriptures alone as the regulative principle of the church. That is to say, the worship of the church, the government of the church, the doctrine of the church, and our understanding of what the church should do or the task of the church. All of these things must be governed by the Word of God and the Regulative Principle which says that if God does not command it, it is no part of the government task doctrine or worship of the church.
