Dishonesty is rampant in all religions. It amazes me that even those experienced theologians, priests, etc., who also come to the realization that there is no God, still keep on perpetuating the myth as they don't know what else to do with their lives. I have heard many religious folk argue the 'faith and truth' point and they normally end up saying that only God is the absolute truth in the universe. Where they get this idea from is beyond me. If you ask them they have no answer, just that its in the buybull. As an atheist I often find it quite hard to be respectful or acknowledge religious beliefs, ceremonies, etc. Once the veil of religion has been pierced it is impossible to fix it.

I think you'll find that those who have no other argument will stick with it even if they've been proven wrong. Too few people are willing to accept that their position is flawed, so they fall back to old arguments no matter how bad they are.

christian thought operates on a proto-rational level, and in domains that sane people wouldn't really understand.

Pretty sure faith is just an assumption without evidence.

Yes, lying is bad.

Yes, they do it often.
