I only read James for now. My small group used it as a discussion book and we plan on returning to it later I do some of the other letters.
It was helpful to have read Wright widely prior to this so that I could explain more fully what wright meant sometimes. He barely hinted at some of his ideas that he developed more fully in other places. Of course this is not one of his full books of theology so he does not have the freedom to fully develop some of the ideas.
But overall it was a good jumping off point for discussion.
