I'm well aware of the leaven. What you have yet to do is detail exactly what heresy these men are teaching. What are they preaching that is contradictory to scripture? If you can't give an exact answer then your statements are nothing more than opinion. I have never heard of these guys until your post so don't think I am trying to defend their position. You say they are unbiblical teachers, without clear examples of anti-Biblical teaching it sounds like gossip.
