I began to post on the various stories of Jesus' atoning work as told by the Church through the centuries: recapitulation and ransom, which were to be followed by satisfaction, penal substitution and example, as found in Scot McKnight's book, Embracing Grace: A Gospel for All of Us.
I've come to realize, in reflecting on it, that I simply am not qualified. I could see that I was writing these summaries from too narrow a perspective (my own tradition, which is only part of the Christian faith) and most importantly, that I lack the necessary reading to do so.
As so many of us do, we depend on good Christian theologians and scholars a great deal in trying to better understand God's revelation to us. I would especially recommend Scot's book since it is clear and can be depended on for a good overall view of these matters.
