The "regulative principle" is the Reformed view of how God regulates our worship and provides that worship is by divine appointment. Everything we do in worship must be divinely warranted. And since Scripture is the sufficient Word of God, everything we do in worship must be "prescribed in the Holy Scripture."
So defined, the regulative principle is eminently scriptural. In biblical worship, we seek God's glory, not our own pleasure. And we have no sure way of determining what pleases God in worship except God's own revelation of Himself in Scripture. So Scripture is sufficient to tell us God's will for worship. We dare not add to, or subtract from, God's own Word (Deut. 4:2, 12:32, Rev. 22:18-19).
But when you think about it, the regulative principle is not limited to worship services. It is God's regulative principle for all areas of human life.
