There’s one of these “King James Believing” Baptist churches near my house. Apparently, the idea is that the KJV — translated, mind you, fifteen centuries or so after the New Testament under the authority of a semi-Catholic monarch — is the unerring Word of God. I don’t think most of the others go to the extremes of saying that the other Bibles should be burned, but given their premises, it’s not too surprising. The ultimate expression of a certain strain of Baptism is one guy holding a flamethrower shaped like a Bible.
Contemporary Christian music really is a tool of the Devil, though.
