See my prior posts. Among other posters who have explained it repeatedly. Core beliefs. You believe the same thing and it unites you under a common banner. Little details are irrelevant.
But believing you will one day be a God is not consistent with any of the denominations you mentioned. It is a core belief apart by orders of magnitude.
The Devil days something similar. Should we consider Satanists Christian too? Yes or no please.
How do authorities measure “distance” in beliefs? At what “distance” do they draw the line of acceptability? Where is the canonical list of Christian core beliefs and the list of distances that each sect of today lies from them? How would they rate, for example, “Assemblies of Yahweh”, or “Kimbanguism”?
