It seems all too easy for us to over-complicate Christianity. There are complex angelologies and demonologies, catastrophic eschatologies and medieval metaphysics to name a few. Perhaps we're embarrassed about the origins of our faith, that it's too simple or lowly.
The solution, I think, is to remember that the whole of Christianity begins and ends with Christ. Once we identify Jesus (the peasant from Nazareth) as the total embodiment of God, we are obliged to obey his commands. And his commands were quite simple: love one another.
We can spend hours and hours figuring out what this means in daily practice. In fact, that's something we should definitely do. In fact, I imagine that if we did that, we'd spend less time with the trivia of our faith, and more time making the kingdom of God a material reality.
