There is a difference than what Jesus did and what you are doing though. Jesus was harsh on the Pharisees because they claimed to believe and follow God, but clearly didn't. Same with the Jews. He isn't claiming to follow God and just believes something different then you. The goal should be to show him the truth not condemn him. If a brother leaves your church do you tell him he is going to hell or do you try to get him back? You can tell someone they are wrong, and TEACH them, without condemning them. Jesus taught everyone he could, and only after attempting to teach did he condemn. I understand I am less experienced then you, but if our goal is to bear fruit, going around preaching damnation is not how to do it.
