"Rather than defending the Gospels against their (self-evident) diversity, we should be asking ourselves why they are different at all. Why are there four versions of Jesus's life out there? I can think of a few reasons why these differences exist. No one was taking notes as Jesus was talking, and so the stories got jumbled by the time they went from oral to written form. And we humans have faulty memories and "remember" events differently. But I think the main reason they differ so much is this. Each Gospel writer took it upon himself to shape--not simply report--the story of Jesus the way he saw fit, to present Jesus not as an academic exercise in historical accuracy, but as a way of encouraging and strengthening the community for which he was writing. To put it another way, each Gospel is its own unique retelling of the life of Jesus centered on the needs of each writer's community of faith."
