Omega i wouldnt say that all those branches in Christianity are all "Christian" denominations.
Would you consider a Unitarian a Christian? even though they say Christ was a mere man?
Or perhaps the Jehovah's Witnesses, would you consider them Christian? even though they claim Jesus to be the Arch angel Michael?
I mean they are both Christian denomination but are they really christian?
do they teach the fundamental Christian teachings?
For Example the Trinity?
