Modern Christians, even (especially?) modern theologians, seem to forget that Christ's power is put on display by His triumph over His death, not just by that death alone. Remove the resurrection - and the theism - from Christ, and you're no longer left with an event of much interest in and of itself.
See, I'm saying something that should be obvious - you don't need a divinity degree to 'get' this - but it also doesn't sit well with some people. No, no, no, victimhood is noble -itself-. Christ's strength was His - pardon, his - weakness. Omnipotence is irrelevant. Resurrection is irrelevant! It's the injustice which is striking, it's the suffering and the death and how wrong it all was, and that is it. That's what's central, that's the lesson, that's what we should notice.
This is one of those things which is supposed to seem dramatic and poetic and deep, but I've never been able to get on board with this kind of schtick. Christ is important because Christ is God. The crucifixion is important because of the resurrection. I know that keeping the dirty theistic details in the story makes it less palatable to non-Christians, but come to think of it, making it palatable to them isn't that important either.
