"Accordingly, we assume that the three patriarchs of Israel---Abraham, his son Isaac, and his grandson Jacob---were monotheists, that they believed in only one God. This does not seem to have been the case. Indeed, it is probably more accurate to call these early Hebrews pagans who shared many of the religious beliefs of their neighbors in Canaan. They would certainly have believed in the existence of such deities as Marduk, Baal, and Anat. They may not all have worshipped the same deity: it is possible that the God of Abraham, the "Fear" or "Kinsman" of Isaac and the "Mighty One" of Jacob were three separate gods. <br>         We can go further. It is highly likely that Abraham's God was El, the High God of Canaan. The deity introduces himself to Abraham as El Shaddai (El of the mountain), which is one of El's traditional titles. Elsewhere he is called El Elyon (The Most High God) or El of Bethel. The name of the Canaanite High God is preserved in such Hebrew names as Isra-El or Ishma-El." -An excerpt from "A History of God" by Karen Armstrong. <br>      The truth is that the Abrahamic religions (Judaism, Islam, and Christianity) all emerged from pagan polytheism.
