I am resurrecting this old thread because I stumbled on a verse today that shows explicitly that Jesus Cross is considered to be a sacrifice of atonement.
Romans 3:25
God presented Christ as a sacrifice of atonement, through the shedding of his blood—to be received by faith.
The reason I think this is important is because the idea of atonement or "covering" is rich in the OT and is usually in line with a blood sacrifice. This would mean that the sacrifice of Jesus is in fact in line with those sacrifices of blood atonement covered in the OT. It would be a very interesting blood atonement in that it is a human being, the Son of God, perpetrated outside the temple cultus through God's enemies, enemies used for a Divine purpose for their own possible redemption, a blood atonement sacrifice that oddly enough can only be received on faith, and the sacrifice of blood for a New Covenant to replace the old one at Sinai where blood was sprinkled on the Israelites. I have heard it argued atonement goes all the way back to Genesis 3 when a lamb is killed to cover the nakedness of Adam and his wife with its skin.

I now wonder if the idea that Jesus' sacrifice on the Cross is a blood sacrifice, in order to cover us as sinners, is in a form of competition with the idea that the Cross is more of a courtroom drama, as usually portrayed in substitutionary atonement. Could we be reading too much of ourselves and our more modern societies into the atonement of Jesus since the Reformation? By that I mean, I have seen nothing but OT foreshadowing of Jesus' Cross explained in OT terms in the bible. Are we being like Anselm in coming up with something new and unique to explain the atonement that doesn't seem spelled out biblically?
What strikes me now is Paul's explanation of his own upcoming beheading. He calls the shedding of his blood a drink offering (2 Timothy 4:6), something in line with the OT cultus that would denote it being very pleasing to the LORD. This may seem shocking, especially given our modern debates on the problem of evil, but it exposes our common belief in Christianity that wrongdoing always goes against the desired will of God. That wrongdoing, as happened to Job and Jesus, can be God's desired will because they serve a higher purpose to the LORD.
