Jonathan Pageau offers that the highest value in Christianity is love; it is this that is at the top of the hierarchy. His comments, reasonably well-captured, I hope:
Jonathan Pageau: But there’s a key in that, in the “love your enemy” thing. It’s important to understand it. One of the problems of reality that these hierarchies of tribalism, these hierarchies of identity are inevitable. You can’t avoid them. They have to exist or else the world stops to exist; it ceases to exist.
And so, how do you deal with it? A lot of the Christian answers are something like that: love your enemy. Love your enemy doesn’t mean that he’s not your enemy. It’s not saying that this person is not your enemy. It’s saying that this person is your enemy; you have to find it in yourself – and you can still defend yourself, actually.
In terms of Christian understanding, no Christian country would say you need to let yourself get invaded by another country. But the idea is that you need to continue to see the humanity of even the person that’s attacking you, and to see that they share something in common with you, even though they are your enemy.
