For those who have followed the work of NT Wright on Paul and justification (covenental nomism, justification/vindication as confirmation of convenant membership, etc.) will find the following disucssion of NT Wright's Ordo Saludis - order of salvation, quite interesting.
I found this essay to be excellent and helpful in understanding Wright's departure from the Reformed view.
Bishop NT Wright's Ordo Saludis
Especially interesting to me was his mention of Wright's lack of engagement with the doctrine of sanctification - this is not surprising in light of the new perspectives views make justification very akin to some reformed sanctificational views.
