If some idiot renounces Christianity because he follows a workout tape that teaches him how to breathe and stretch in sync, then that idiot isn't long for the faith anyways.
If you do yoga, Satan will subvert your mind into becoming a Hindu. If you read the Iliad, you'll become a pagan. If you listen to rock music, you're worshipping Satan. If you read a book on the history of Japan, you'll become a Shintoiest, ie, a Satanist. If you read the Lord of the Rings, you'll become a wiccan who believes in earth witches. If you read Hamlet, you'll emulate your role model Hamlet like the good monkey you are and commit regicide. If a woman wears a dress, a man will definitely lust after her and he will rape her. If a church puts on a play--any play--that church is falling away as prophesized in Revelation because it is embracing pagan roots --after all, it was the ancient Greeks who invented the play, therefore all plays should be banned. Oh and alphabets? Don't get me started on alphabets and those pagan Phoenicians. Better wrap everyone up like bhirka mummies so they won't be exposed to anything.
Malachi 1:11..."For from the rising of the sun even unto the going down of the same my name shall be great among the Gentiles; and in every place incense shall be offered unto my name, and a pure offering: for my name shall be great among the heathen, saith the LORD of hosts."
...So long as the Laws of Noah are adhered to - whether one knows them by that name, or not.
