Old Testament Abraham, the" father" of three religions.
Would some good folks a lot better schooled care to discuss Abraham?
I have heard people refer to Abraham as the father of three religions for ever.He was the father of two bloodlines.One with Sarah his wife that would become the twelve Hebrew tribes.From these will come Judaism and Christianity.Abrahams other bloodline was through Hagar a slave to Sarah.Through this bloodline would come the twelve tribes of Arabia.Islam will come a couple thousand years later.This is why it is hard to call him the father of three religions.
