"The three great faiths called Judaism, Christianity, and Islam were born of an event that each remembers as a moment in history, when the One True God appeared to an Iron Age sheik named Abram and bound him in a covenant forever. Abram is the later Abraham, the father of all believers and the linchpin of the faith, and indeed the theology, from which the three communities of that God's worshipers emerged. The history of monotheism had begun."
