Rejecting the sinner in any manner is strictly against the teachings of Christianity.
Quote:
And it came to pass, as Jesus sat at meat in the house, behold, many publicans and sinners came and sat down with him and his disciples.
And when the Pharisees saw it, they said unto his disciples, Why eateth your Master with publicans and sinners?
But when Jesus heard that, he said unto them, They that be whole need not a physician, but they that are sick.
But go ye and learn what that meaneth, I will have mercy, and not sacrifice: for I am not come to call the righteous, but sinners to repentance.
Matthew 9:10-13, KJV.
Of course, Jesus also condemns any divorce not caused by adultery, saying that those that divorce and get remarried in such cases are in fact committing adultery themselves.
So divorced and remarried couples, or parents that work on the Sabbath, both of which are cardinal sins, are okay, but if you violate a rogue passage of Leviticus, boy are you in trouble.
Here, people:
STOP CALLING THESE PEOPLE CHRISTIAN. They're not doing jack s**t "because it's what their religion says". They're doing exactly what they want to do and nothing more or less.
