Slipping into my internet vestments, I’ll give you a pretty good clue as to what G-d may think, as well as pointing out the obvious: what christians sui generis think about themselves.
In no particular order: Jehovah’s Witnesses. Catholics. Presbyterians. Lutherans. Mormons. Episcopalians. Methodists. Unitarians. Baptists .... and on and on and on.
This is what they call themselves and what others call them.
Setting aside their literalist dogma, stubborn faith and eschewing, almost Amish, lifestyles—the fire and brimstone sermons: hair-raising things to experience—what do members of the Church of Christ call themselves?
Christians.
No, hardline CoC’s call themselves the ONLY (real) Christians. That is why they should be called a cult.
