@NEETzsche @Omega_Variant @PodunkPotato @Quentel @cowanon I can give you the exact criteria by which they aren't Christians.

You have to serve the Jesus Christ that actually existed to be a Christian. Those groups made up new, fictional Christs, who were similar only in name. Their Jesus is about as real as the Easter Bunny.

Only one Jesus actually existed in history.

This isn't a game where we get to pick multiple options from a buffet. If you don't follow the real thing, you burn forever in the Lake of Fire.
