"I think you're right. I don't really have enough technical knowledge to talk about it in depth either, but based on my experience and background, which sounds very similar to yours, it seems that any onto-theology will necessarily be foundationalist by virtue of the metaphysics it acquiesces its theology to. That's one reason why I'm really drawn some of the discussions (John Caputo, for example) going on in the continental philosophy world surrounding what a theology might like after Heidegger and after metaphysics proper." - Blake Huggins
