Here's a link to an interview with Prof. Bart Ehrman (UNC Chapel Hill) on his new book published by HarperOne, Jesus, Interrupted: Revealing the Hidden Contradictions in the Bible (And Why We Don't Know About Them). A discussion ensues focusing (amongst other things) on Jesus' last words on the cross which in Mark are "My God, my God, why have you forsaken me" and in Luke, "Father forgive them, for they know not what they do." To conflate these two accounts does justice to neither gospel since a different portrait of the dying Jesus exists in each gospel. In Luke, Jesus exercises self-control and addresses remarks to another person crucified next to him. In Mark, Jesus' anguish is palpable. In John's gospel, Jesus' death is his exaltation to God.
