Debatable, but many do add (and I'm not learned enough to agree or disagree) in the Churchs that agree to Apostolic Succession -- like some Lutherans, Anglicans etc.
Beyond the Apostolic Churchs you have the groups that broke away and are outside the Apostolic Church -- they PROTEST basic dogma (e.g. free will versus robots condemned to heck or not among many other things) -- so, your group would belong to this PROTESTANT Christian grouping. Within the PROTESTANT Christian grouping you have you might say there are 5 or 6 generations of thought:
As I've shown above -- the final teachings of Unitarianism (Universal or "Christian") or Mormon doesn't seem so strange if you go by the above lines of progressions. That's what happens with deviation from God's teachings -- the first make a few changes that don't seem like too much, but where does it all end? It's like the Anglican Church first said that contraception was fine, then that abortion was fine, then gay bishops and marriages were part of god's will.
"Note -- Catholics ARE Christians. The Apostolic Churches (from East to west) are:"

I use to think so, but the more I've studied SCRIPTURE and seen the deviations from SCRIPTURE and promotion of its own institution in the Roman Catholic Church I'm not so sure that's true. BTW if you ask a Roman Catholic what they are more often than not they will say "Catholic" not Christian.
