Oddly, no one in this thread seems to have looked at what Jesus said about the significance. The words of institution refer to the blood of the covenant, which Luke and Paul understand as a new covenant.
That’s a quotation of Ex 24:8 and Zech 9:11. In the OT sacrifices were used for different things.
They’re not all sin sacrifices. Making a covenant could also involve a sacrifice. Why? That’s speculation, but
sacrifice isn’t just (maybe isn’t at all) vicarious punishment. There are also “fellowship sacrifices”, which seems to be a meal shared with Gid.
Not all sacrifices were
for atonement, but all sacrifices were based
on atonement.
Although not a sacrifice for sin, the element of substitutionary atonement is in the sacrifices of worship and fellowship because the atonement is the
basis of all acceptable worship and fellowship.
I assume for a covenant sacrifice, the blood indicates the seriousness of the commitment. That’s how Zech 9:11 seems to see it. Because of the blood of his covenant with his people, God is committed to saving them.
Indeed.
However, the blood of covenants was not a sacrifice
per se, because it was not burned on an altar.
In those times, parties solemnized the cutting (making) of a covenant by walking down an aisle flanked by pieces of slaughtered animals (
Genesis 15:9-11,
Genesis 15:17;
Jeremiah 34:18-19)
--the smoking pot of
Genesis 15:17 symbolizing the presence of God (
Exodus 3:2, 14:24, 19:18;
1 Kings 18:38; Acts 2:3-4)--
signifying a self-maledictory oath: "May it be so done to me if I do not keep my oath and pledge."
It’s possible that this is Jesus’ understanding. But if Luke and Paul are right that Jesus referred to a new covenant, this is likely a reference to Jer 31:31, which refers to a new covenant,
Jesus himself said the "
cup is the new covenant in my blood" (
1 Corinthians 11:25)
the people are renewed by the law written in their hearts. This is certainly consistent with Jesus teaching, which sees the Law as fulfilled by love, and deemphasizes the letter.
So how might his death establish this new covenant?
The shedding of his blood on the cross was the cutting (
making) of the new covenant.
Paul gives his understanding of the atonement in Rom 6.
Rather than the atonement itself, would that not be his understanding of the
effects and
results of the atonement for those of faith?
His understanding of the atonement itself is in
Romans 3:25--atonement is through
faith in his blood.
He says that through union with Christ we die to sin and rise to new life with him. This new life is the life of the new covenant. Participating in communion in faith is a sign and a means of participating in this.
Indeed. . .and a proclamation of the Lord's death (sacrifice; gospel) until he comes (
1 Corinthians 11:26).
