No doubt. On the other hand, sometimes the analysis overlooks something. In the case in question when WE read the sentence we saw three notions about the atonement and I understood you to say that there was only ONE notion and that was the "exemplary" notion. And in answer to this point annalex says there is a "blood atonement" in Catholic thinking.
I would have said that in both the Satisfactory (Anselm) and in the Sacrificial notions blood was central. One "use" of sacrificial blood in Leviticus is to re-make a connection between the Lord and His people, so both the altar and the people are Sprinkled with blood. And we who make so much of the Blood of Christ in the Eucharist, "my blood of the new covenant", I would have expected to be told it's too much a part of our thought and spirituality, not that it's not enough.
I bet we may find a miscommunication on "blood atonement", that's what I bet.
Apparently you haven't read New Advent. This is not Catholic teaching I regret to say.
