"av said This blurs the line between visible church members and the world. COuld you provide scripture for this approach?"

It doesn't blur the lines at all. It keeps me from making judgements about others.

I know all are sinners. Those I meet who are not believers, have not repentad yet, I will not judge as being "unelect". That's not up to me.I don't believe the 2 statements contradict each other.
