Steve Lennox spoke on atonement in chapel today. Eventually, you will be able to hear it on iTunes, launching from this webpage. He came up with a nice little acrostic on atonement:
L = liberation from the power of Sin (I suspect we might map this to Christus Victor too, victory over evil powers)
O = order (here he covered satisfaction type material--the need for balance in God's creation and justice)
V = vicarious exchange (substitution type material)
E = example (moral influence type material)
There was good application stuff to the tune of about 6 points, but I didn't write it down. So you'll have to listen to the podcast.
By the way, I also found out that Peter Enns is now attending a Nazarene church. Welcome to the Wesleyan tradition! Unlike the PCA, we don't eat our young... at least not as often :-)
