According to Swinburne, one way of dealing with the guilt that attaches
to a morally bad action is satisfaction, consisting of repentance, apology, reparation,
and penance. Thus, Christ's life and death make atonement for human sin by
providing a reparation which human beings would otherwise be unable to pay. I
argue that the nature of God's creative activity entails that human beings can by
themselves make reparation for their sins, merely by apology. So there is no need
for additional reparation, and the satisfaction theory of the atonement is otiose.
Following an insight of Swinburne's, I argue that satisfaction is not sufficient for
forgiveness, since satisfaction does not place the wronged party under any
obligation to forgive the wrongdoer. Christ's death merits the forgiveness of those
sins for which human beings have made satisfaction. It does this in virtue of a
divine promise to reward Christ's meritorious life with the forgiveness of such
human sin.
