No, we condemn Gnostics, Manicheans, etc. who are not Christian and pretend to be — like Mormons or JWs. Oh, sorry about the JW bit if that offends you
Doesn't matter who you condemn...Your condemnation means nothing...What counts is God's condemnation...And His doctrine that he passed on to Jesus which is in the written scripture...
Change it all you want at your own peril...
