Christianity is an exclusivistic religion. Therefore, there can only be one God their God, there can only be one moral code their moral code. All other moral code are false and wrong and if you don't accept their God as the one and only true God you are an atheist.
If you don't believe that your religion is correct, why do you bother with it?
Isn't a lack of a solid religion or moral code just as valid?
If your religion is correct, how can other religions also be correct?
Nobody is really without a religion, what they look to for guidance just varies.
