The text of an excellent sermon delivered at Grace Valley Christian Center can be found here. Below is an excerpt from that sermon that discusses both expiation and propitiation:
“In the Greek, the word “to propitiate” is hilaskomai, which means to appease, to placate, to avert, to turn aside the wrath of an offended person by means of a sacrifice. Four things are involved in propitiation: First, there is an offended deity; second, an offending sinner; third, the offense committed; and fourth, the sacrifice which removes the offense and causes the offended person to be gracious to the one who offended him. Salvation, in the Christian sense of the term, requires one very definite type of sacrifice, namely, propitiation. It is directed toward God to turn away his wrath, which is revealed against our offense, that he may be gracious to us.
“For the past century and a half, the idea of a God who is wrathful and opposes sin and sinners has not been accepted by unbelieving theologians. They readily will choose the conception of God as love but want to forget about the idea that God is holy. The notion of an angry God, they say, is not Christian, but pagan. They say the God of Christianity, in their highly evolved conception of it, is always a loving, nice God. When they translate the Greek word hilasmos, as found in 1 John 2:2 and 4:10, they reject the word “propitiation,” preferring to use the word “expiation,” which has to do with the cancellation of sin, but has nothing to do with a sacrifice offered to God to turn away his wrath.
Expiation means that God has canceled our sin and now there is nothing to worry about, but it is not the same as propitiation. One scholar wrote, “Those who hold to the ‘fire and brimstone’ school of theology, who revel in ideas such as that Christ was made a sacrifice to appease an angry God, or that the cross was a legal transaction in which an innocent victim was made to pay the penalty for the crimes of others as a propitiation of a stern God, find no support in Paul. These notions came into Christian theology by way of the legalistic minds of the medieval churchmen.” We must ask: If Christ’s death on the cross was not propitiation, if this sacrifice was not offered to God to turn away his wrath that he may be gracious to us and forgive us our sins and restore us into his fellowship, if the liberals are right that God is love all the time and never angry at sinners, then what is the need for Christ’s death even as expiation? It is doing nothing to God. Why doesn’t God, being nice and loving, just forgive our sins almost automatically whenever we commit them?” Christ, Our Propitiation,1 John 2:1,2 | Sunday, January 14, 2001 By P. G. Mathew, M.A., M.
