Actually, even the Islamic regions of the Northern and Western Indian subcontinent had once been Christian, and still show many signs of Christian syncretism.
I know... but too big a subject to even broach in a multi-religious site..
The question , "What even, IS a christian ?" cannot be vetted here congently..
Or pretty much ANYWHERE..
Since Jesus came to make ALL religion obsolete, AND DID..(by his words and action)
Including Jewish, christian and all other religions too.. BECAUSE:..
Jesus by doing this, has made the "relgious" crazy for a couple of thousand years.. up till this day, even here on a pretty intelligent website.. i.e. short blubs are wiser.. not in depth analysis.. on this subject..(in my experience).
After all what would a REAL God even need with a religion..
False cartoon Gods NEED religion, not a real one..
-OR- he/she/it would not be God<<--who wouldn't need gender either..
