• noun This doctrine assumes that sin has made a spiritual separation between God and the human soul. Different systems of theology explain differently the method of reconciliation, and therefore use the word atonement with different meanings. The early fathers generally stated the doctrine in the terms of Scripture, and it was not until the time of the Reformation that the differences in philosophical statement were clearly marked. The modern statements may be grouped under four general heads, as follows: A reparation or satisfaction for sin made by the sufferings of Christ as a substitute for the sinner, and in lieu of the punishment to which the sinner was justly amenable. Such satisfaction is regarded as necessary either to satisfy the justice of God, and so make forgiveness possible, or to satisfy the law of God, produce the public impression which punishment would have produced, and so make forgiveness safe. The former is known as the satisfaction, the latter as the governmental theory.
