Of course! Indoctrinate them while they are young. Fill them with your ridiculous dogmas while they are still developing, because if you wait until they are adults, they won’t be stupid enough to accept your religious idiocy. Make sure you use fear and punishment too. If you don’t establish the idea of sin when they are young, they might grow up to be fully-functioning, well-adjusted adults and we can’t have that, now can we?
