I know nothing of this Origen guy, but just from your explanation, he sounds a lot like what I see as well. For me there is a bit of a difference as to how we can see the third dimension.
First dimension for me is again, the literal story
Second dimension is the moral of the story
Third dimension is the inward application. . .which is what I call the spiritual because rather than studying really hard, for me, it's not something that comes through my mind in heavy labor .. . but rather it's simply 'revealed" through my relationship with the Father. Flesh and blood can't teach it. It's the Peter experience.
