That;s not what the Bible says.
A church should accept anyone who is truly repentant for anything wrong they've done and who sincerely want to live in the truth of the Gospel.
But if someone in the church rejects the Gospel they need to be ejected until they repent.
Oh, yes. I was referring to the leadership. If someone in the leadership is going to openly sin (such as homosexuality, adultery) and not repent, then they should be removed immediately.
I was meaning that someone should never be rejected from attending worship service.
