This makes them quite borderline. Campbellism is heresy. Yet James did not want me to evangelize them. Perhaps I should.
I would definitely suggest you do not evangelize him/them. Not because of him, but becaus of you
You don't understand the issues well enough. Your style does nothing except entrench people in what they already believe.
It's similar to a scenario about 17 years ago, where a Baptist friend of mine was "debating" a Jehovah's Witness. Neither one knew the scriptures, neither one understood the other's position, and both had been indoctrinated.
So they start off disagreeing, and the first point the JW makes, my buddy comes to me and asks about it. So I helped him understand it, and he goes full throttle and stumped the JW, who in turn eent and asked his dad. So he comes back and makes a point that brings my buddy back to me. And on and on.
After 5 or 6 bats of the birdie, I told my buddy I would not answer any more questions, and he needed to give up his efforts before he ended up being converted.
The only difference is that you are up against someone who is capable, and you're not.
I'll say this with all sincerity, John. You need to stop trying to proselytize, before you end up against someone who is able to twist your thinking just right. If you're not careful, you're just liable to be converted to one of these fringe groups or a cult
