Lets face it, every Christian is a heretic in some way.
Perhaps you think that "Jesus was born as a mere (non-divine) man, was supremely virtuous and that he was adopted later as Son of God" by the descent of the Spirit on him. Heretic! That is called adoptionism.
Perhaps you think Jesus was created by God. Heretic! That is called Arianism.
Think Jesus had a divine side and a separate human side? You heretical Nestorianist!
Think that humans have a divine soul that is trapped in a body? Gnostic!
Ever talk about the Trinity is like water in that it can be three things (solid, liquid or gas) but is still one thing? Modalism!
Think the trinity is like an egg where there are three different parts to the whole? I ought to trump you up on charges of Partialism!
I could go on. We are all heretics by someone elses (past or present) understanding of what is orthodox.
So before you or I begin to argue and condemn a fellow Christ follower we view as unorthodox or heretical or holds views that are "counter to the word of God", slow down and breath and perhaps you too will see that we all are heretical in some form or fashion but that does not mean they are evil/bad/horrible/jerks who desire nothing more than to destroy the church and blaspheme against God.
It could just be that everyone is trying the best they can to describe the indescribable.
