It's not whether one may have some valid points, it's the claim to have all the answers and be "the way". Use of terms like "apostate" (such an ugly term) as if more false answers and use of the same Roman-erroneous Scriptures is any better. A spirit of humble working together is "the way" much more than a "particular group" is "the way". After all, people believe the Bible is the word of God, as you are using it, but no basis for that either, except what a fellow human tells us. There is the "religion group" game. There is also the "open and honest" humility game. You could respond to my other post if you'd like, about Jesus as angel error. Not that I believe in that game but sometimes one must play one game to get to the real discussion. Religion is not a job to be done blindly and ignore things that show flaws in a particular group's reasoning. Religion is sincerity, not - dominance, and one must be "under" a particular group and then they will "behave". With intelligence one can discern the difference in the approach with pre-canned things (like "apostate") and not be preyed upon by any particular group that say that "they have the answer".
It's would be so refreshing to see someone humbly say "yes, you're right, Jesus as an angel doesn't have a strong Biblical basis except if I simply claim that's my belief". I don't use the Bible this way anyway but for those who insist on it, then I'll will go along simply to show when even their use of the Bible doesn't fit.
I don't have all the answers, that's my group. That's the group I'm recruiting for: The "We admit that we don't have all the answers but we do believe in God and we do know to be gracious to our fellow human beings" group, That's my group. People can join that group, and put their walls down, and have actual real conversation.
