Hello Stephen,
Thanks for taking the time to respond.
Duns Scotus certainly has an intriguing take, I’ll grant.
But in this matter, we don’t need to go beyond the Bible itself to know what Jesus’ sacrifice accomplished.
The entire sacrificial system of the Tabernacle and Temple point to it. The same God who took on flesh to die on the Cross as our sacrifice is the same God who built the entire system of sacrifice. He did this to teach His people atonement. He did this to teach that the life is in the blood, and the blood makes atonement by the payment of life for life. He did this to emphasize the necessity of a pure and spotless sacrifice. He did this to teach that the sacrifice is personal (relating to the individual worshiper) and corporate (the scapegoat upon whom the High Priest confesses all the sins of Israel).
Everything Jesus said about His own sacrifice assumes that you understand this sacrificial system first. When you do, the meaning is quite clear.
