Soteriology

From the Greek sōtēria, salvation. Every religion with a concept of ultimate human problem and ultimate human rescue has a soteriology, though the shape of the problem and the nature of the rescue vary enormously. Christianity centers its soteriology on the death and resurrection of Jesus, disagreeing internally about whether salvation is by faith alone, by faith and works, or by participation in the sacramental life of the church. Buddhism's soteriology is the path out of suffering through the eightfold path. Hinduism offers several — bhakti (devotion), jnana (knowledge), and karma (disciplined action).

Within Christian theology, the major atonement theories are the classical answers to the question "what did the cross accomplish, and how?" Ransom theory (early church) held that Jesus's death paid a debt owed to Satan or to death itself. Satisfaction theory (Anselm, 11th century) held that sin dishonored God's infinite dignity, and only an infinite payment — made by a God-man — could restore it. Penal substitution (developed by the Reformers) held that Jesus bore the punishment sinners deserved. Moral influence theory (Abelard) held that the cross was primarily a demonstration of God's love, moving humans to repentance.

Soteriology matters because it is where religious claims become most practically consequential. Doctrines about who gets saved and how determine who is in the community, who is outside, what the community owes outsiders, and what the individual has to do to be in good standing. Disputes about soteriology drove the Protestant Reformation, the Great Schism, and most Christian denominational splits since.

For a secular reader, soteriology is worth knowing because it clarifies what religious people think they are getting from their religion. Arguments about religion that ignore soteriology tend to miss what the believer is actually holding onto — not a metaphysical theory but a rescue.
