“. . . strict Saudi interpretation of polytheism includes Shiite and Sufi Muslims as well as Christians, Jews, Hindus, and Buddhists.”
The little I know about the religion, I can see how Hindus could be deemed polytheistic.
And I’ve seen it logically argued (arguments with which I disagree) that the Christian Trinity is semi-polytheistic.
No clue about Buddhists.
But Jews? GMAFB.
Yeah, I’ve never heard even the most radical Muslims say that Jews were polytheistic. That’s a new one. Shi’a polytheistic? I’ve never heard that one either, just that they are idolatrous & way out of the bounds of Islam.
I was always told that Christians believe in 3 gods, both by other Jews & Muslims.
