I have a question to ask you folks:
Me? Its gotta be the violence of God in the Old Testament. I can handle textual composition problems. I can handle problems of causality and God’s power, and I can deal with contradictions between the narrative of the Bible and what we can tell about the world through science and history. But when I look at the God of the New Testament and the God of the Old Testament, I can understand how some early Christians opted to ignore or reject the Old Testament completely. I am no where near close to doing that, but I am just saying that I can understand the impulse.
So, what does this for you? Be honest. There’s gotta be problems that you are struggling with (or you are probably ignoring implications of certain things).
Update: There is another question that I run into when I study the New Testament period. It has the potential to reshape the way I look at the canon we have constructed. I’ve wrestling with it for some time. I hope to be able to articulate it well sometime soon in the future.
