There is no regulative principle when it comes to purifying the church...you DO it when evil creeps in. There is on worship (just read the OT where God says you can only do in worship what he commands and there is NOTHING in the NT which repeals this). Thus, your point is not valid.
There is no regulative principle when it comes to purifying the church...you DO it when evil creeps in. YOU? Doesn't God have anything to say about it? Oh, I get it "divine inspiration" allowing YOU to destroy the very house He built!
How do we know Calvin wasn't the evil you describe?
As for the rest of your answer... I don't believe in your version of the bible... prove to me it's the correct version!
