“Once you let go of the Bible as history, all Christian doctrine begins to disintegrate.”
If you read the bible as history I think you miss the point. When Jesus fed several thousand people with fish from a basket he wasn’t trying to tell us about himself. It is beside the point whether he actually did it or not, the point of the story is about faith, not about the ability of Jesus to perform miracles.
One point of the miracles is that faith doesn’t come from them. Saving faith is a gift of God.
“not about the ability of Jesus to perform miracles.”
Then who is Jesus and why should I believe what he has to say about faith?
