I started reading Gerhard Von Rad's seminal OT theology yesterday. I've given up though as it seems so concerned with getting behind the text, rather than listening to it, and I have a load of other books waiting in line. But before I gave up I came across a neat little summary of the nature of OT sacrifices.
- gift
- communion
- atonement
Not profound, but a helpful little framework. I think it only leads to misunderstanding if we overemphasise any one of them.
