You welcome people, but they cannot officailly join unless they've demonstrated that they've changed.
If an ISIS soldier was still looking to kill Christians, would you welcome him with "open arms", therefore endangering your congregation?
The "welcome them" argument is fallacious on its face, and an ear-tickling thing to say.
I'd say anybody could join that wanted to be there.
And no, if the ISIS soldier was still on the hunt, I'd call the cops and/or shoot him in defense. Not the same situation. My point was that any soul that is hurting and is there for God's love would be accepted. If you're their to burn the place down, then gtfo.
I don't go to church much though, so I'm just saying IF....
