As BuckW pointed out, the Catholic Church doesn't seem to believe "Evolution = atheism."
I guess everybody's entitled to his own opinion. I stand on scripture, that's all.
So you're now backing off your previous statement, "That's a joke, right? By definition, a real Christian is a Bible-believer. Evolution = atheism."
I'm sure the Catholics will breathe much easier knowing you're willing to allow them to be Christians.
