The regulative principle of worship is the idea that we must worship God the way He wants to be worshiped, and that He tells us how He wants to be worshiped in His Word. The Bible, either by explicit command or by principles we can properly deduce from it, tells us how to worship God.
In 2000 our pastor wrote a paper for seminary on the regulative principle of worship, and in 2002 taught a Sunday School class on the same topic. The same ideas rattled around in his head for a few years, until he updated the paper in late 2014. We hope it is edifying for you. Feel free to download it and share it with others:
