Expiation
What Is Expiation?
Expiation refers to the removal or cleansing of sin and its consequences. While the term is closely related to atonement, expiation carries a more specific focus: it emphasizes the wiping away of guilt and uncleanness rather than the broader concept of reconciliation between God and humanity. In Scripture, expiation is accomplished through sacrificial acts prescribed by God, ultimately pointing forward to the definitive work of Christ.
Expiation in the Old Testament
The concept of expiation runs throughout the Levitical sacrificial system. The Hebrew word "kipper," often translated as "to atone" or "to make atonement," carries the sense of covering or wiping away sin. In Numbers 8:7, the purification of the Levites involves a process of expiation to make them ceremonially clean for service. Deuteronomy 32:43 speaks of God expiating the land of His people, cleansing it from the guilt of bloodshed. The Day of Atonement described in Leviticus 16:30 was the most significant annual act of expiation, when the high priest made offerings to cleanse the people and the sanctuary from the accumulated sins of the year.
Expiation and Propitiation
A key theological distinction exists between expiation and propitiation. Expiation focuses on the sin itself — removing it, covering it, or cleansing the sinner from its effects. Propitiation, on the other hand, focuses on satisfying divine justice or turning away God's wrath. Both concepts are present in Scripture. Psalm 65:3 declares that God expiates transgressions when they become too heavy to bear. Romans 3:25 describes Christ as a sacrifice of atonement, combining both the removal of sin and the satisfaction of God's righteous requirements.
Expiation Through Christ
The New Testament presents the death of Jesus as the ultimate act of expiation. Hebrews 2:17 states that Christ became like His brothers in every way so that He might make expiation for the sins of the people. First John 2:2 describes Jesus as the atoning sacrifice for sins — not only for believers but for the whole world. Through His death on the cross, Christ accomplished what the animal sacrifices of the Old Testament could only foreshadow: the permanent removal of sin and guilt (Hebrews 10:4, 10:12).
The Ongoing Significance of Expiation
The doctrine of expiation assures believers that sin is not merely overlooked but genuinely dealt with. God does not simply ignore wrongdoing; rather, through the sacrificial system and ultimately through Christ, sin is addressed, removed, and its power broken. This gives believers confidence in approaching God, knowing that the barrier of sin has been fully removed (Hebrews 10:19-22).
Biblical Context
Expiation appears throughout the Old Testament sacrificial legislation, particularly in Leviticus and Numbers, where it describes the purification of people and objects from ceremonial uncleanness and moral guilt. Key passages include Numbers 8:7, Deuteronomy 32:43, Psalm 65:3, and Psalm 79:9. In the New Testament, the concept is fulfilled in Christ's atoning death, as described in Romans 3:25, Hebrews 2:17, and 1 John 2:2.
Theological Significance
Expiation teaches that God takes sin seriously but also provides the means for its removal. It demonstrates that forgiveness is not arbitrary but is grounded in sacrificial action. The progression from animal sacrifices to Christ's death shows God's plan to permanently deal with human sin. The concept reassures believers that their guilt is not merely covered but genuinely removed through Christ's work.
Historical Background
Expiatory sacrifices were common throughout the ancient Near East, with various cultures practicing rituals to cleanse temples, people, and lands from ritual impurity. Israel's system shared some formal similarities with these practices but was distinct in its monotheistic framework and its understanding of sin as an offense against a holy God. The distinction between expiation and propitiation has been a significant topic in Christian theology, particularly since the Reformation.
