'Believing' cannot tip the scales in making a historical judgement about whether something really happened. I can choose to believe that George Washington threw a silver dollar across the Rappahannock, but my believing that he did it has nothing to do with whether or not he really did do it. So also with the story of Jesus walking on water: Believing that he did it has nothing to do with whether he really did do it. 'Belief' cannot be the basis for historical conclusions; it has no direct relevance.
Marcus BorgChristianity's goal is not escape from this world. It loves this world and seeks to change it for the better.
Marcus BorgIt is important to show people ways that we can reclaim Christianity from some of the misunderstandings of our time.
Marcus BorgI would argue that the truth of Easter does not depend on whether there was an empty tomb, or whether anything happened to the body of Jesus. ... I do not see the Christian tradition as exclusively true, or the Bible as the unique and infallible revelation of God. ... It makes no historical sense to say, 'Jesus was killed for the sins of the world.' ... I am one of those Christians who does not believe in the virgin birth, nor in the star of Bethlehem, nor in the journeys of the wisemen, nor in the shepherds coming to the manger, as facts of history.
