When we talk about the vicarious aspect of the atonement, and some versions of the Bible will use one of these words and some will use the other one. I’m often asked to explain the difference between propitiation and expiation. The difficulty is that even though these words are in the Bible, we don’t use them as part of our day-to-day vocabulary, so we aren’t sure exactly what they are communicating in Scripture. We lack reference points in relation to these words.
Expiation and Propitiation
Let’s think about what these words mean, then, beginning with the word expiation. The prefix ex means “out of” or “from,” so expiation has to do with removing something or taking something away. In biblical terms, it has to do with taking away guilt through the payment of a penalty or the offering of an atonement. By contrast, propitiation has to do with the object of the expiation. The prefix pro means “for,” so propitiation brings about a change in God’s attitude, so that He moves from being at enmity with us to being for us. Through the process of propitiation, we are restored into fellowship and favor with Him.
In a certain sense, propitiation has to do with God’s being appeased. We know how the word appeasement functions in military and political conflicts. We think of the so-called politics of appeasement, the philosophy that if you have a rambunctious world conqueror on the loose and rattling the sword, rather than risk the wrath of his blitzkrieg you give him the Sudetenland from Czechoslovakia or some such chunk of territory. You try to assuage his wrath by giving him something that will satisfy him so that he won’t come into your country and mow you down. That’s an ungodly manifestation of appeasement. But if you are angry or you are violated, and I satisfy your anger, or appease you, then I am restored to your favor and the problem is removed.
The same Greek word is translated by both the words expiation and propitiation from time to time. But there is a slight difference in the terms. Expiation is the act that results in the change of God’s disposition toward us. It is what Christ did on the cross, and the result of Christ’s work of expiation is propitiation—God’s anger is turned away. The distinction is the same as that between the ransom that is paid and the attitude of the one who receives the ransom.
Christ’s Work Was an Act of Placation
Together, expiation and propitiation constitute an act of placation. Christ did His work on the cross to placate the wrath of God. This idea of placating the wrath of God has done little to placate the wrath of modern theologians. In fact, they become very wrathful about the whole idea of placating God’s wrath. They think it is beneath the dignity of God to have to be placated, that we should have to do something to soothe Him or appease Him. We need to be very careful in how we understand the wrath of God, but let me remind you that the concept of placating the wrath of God has to do here not with a peripheral, tangential point of theology, but with the essence of salvation.
