You reference St. Anselm in regards to the Orthodox teaching. Please look at New Advent. Catholics claim their doctrine is derived (modified) from St. Anselm as well.
I find Catholics tend to say things are inaccurate when, in fact, they are simply an analysis of their own doctrine.
Let us look stedfastly to the blood of Christ, and see how precious that blood is to God, which, having been shed for our salvation, has set the grace of repentance before the whole world. Let us turn to every age that has passed, and learn that, from generation to generation, the Lord has granted a place of repentance to all such as would be converted unto Him. - Clements
My (3) is what you might call blood atonement.
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.
