This is what they say. How is it with their heart is altogether different, much like with the pharisees. Even if they truly don't believe in God, the reason why they only ever choose to oppose the Church is to advocate abominations against natural law, which are knowingly evil even in the absence of revelation.
They should not be feared, but they shouldn't be pitied either.
Forgot to add that near every one of those poohsies would pooh their breaches at the mere thought of sacrificing a baby to a cow demon and would run screeching back to Christ.
