[TBC: The following quote from emergent church leader Brian McLaren documents further his belief that Muhammad’s “revelations” were from the same God that spoke to the prophets of the Bible.]
Christianity, Islam, and Judaism have more in common than many people realize because they all share a primal narrative, and they all flow from a common sacred fountainhead: a single figure, at once famous and mysterious, a Middle Eastern man named Abraham of Ur.
We can date Abraham’s birth to about 2000 BC, in modern-day Iraq, near present-day Nasarif. Like Moses, Jesus, and Muhammad—and like us—Abraham was raised in a pluralistic, polytheistic world. During his lifetime, he lived side by side with others who honored many different gods and practiced many different religions.
And during his lifetime, Abraham—like Moses, Jesus, and Muhammad—had an encounter with God that distinguished him from his contemporaries and propelled him into a mission, introducing a new way of life that changed the world… How appropriate that the three Abrahamic religions begin with a journey into the unknown.
