Judge not lest ye be judged.
The apostles and men of God throughout the Bible addressed what they called FALSE TEACHERS. Deceivers who claim to represent God but do not.
I hardly think "Judge not lest ye be judged" means Jesus wants us to completely naive about such things.
Unless of course He wants to judge His own disciples and men of God in the Bible.
I don't think so.
But nice try anyway! :)
