Sorry you feel that way, this was a different approach I was using here, and there was never any mention that other wizards can't believe in other religions, just that Severus was Christian.  He was refuting Petunia, not badmouthing other religious beliefs.  There will be mention made of other religions as Harry speaks with other wizards and witches who are not Christian and there is no disrespect intended here.  Severus simply is using religion to illustrate the point of forgiveness, which I think is a major concept of any religion.  It isn't as if I've made him a priest who goes around spouting Bible quotes.  You could always skip over the small bits of religion I've inserted, and there aren't all that many, the same way some people skip over CP parts in other stories, for this is mainly a fic centered around a father son relationship and the events in the Sorcerer's stone. 

As for Snape not being in character, he's not like canon, because in this story he was in charge of Harry from the time he was four and always when the child was ill and sick and at his most vulnerable.  Snape does have a heart and is not evil, and after taking care of a child in that manner for years on end, I would think he would come to care and love Harry and be able to look past the fact that he was James's son.  Canon Snape never had that chance, he only saw Harry at school and it was easy to resent the boy who was favored by everyone and who broke rule after rule and was never punished for it. But this Harry Severus only sees as an abused neglected child, Lily's child, whom he has promised to take care of. Unless one has a heart of stone, it would impossible for anyone not to love poor Harry.

However that is your choice and thank you for reviewing.
