What is “penance”?

The story behind the answer

In medieval Christianity, penance was the practical follow-through after confession: a priest assigned concrete tasks—such as prayers, fasting, almsgiving, or a pilgrimage—as outward signs of contrition and a way to repair harm. Forgiveness itself came through absolution; the acts were not meant to earn it or display superiority, nor were they simply self-punishment for its own sake.

Early medieval communities sometimes required public penance for grave sins, but by the High Middle Ages private confession became standard. Penance also shaped popular religion: pilgrim routes flourished, and charity supported hospitals and leper houses. Later debates over indulgences concerned how these acts related to the “temporal” consequences of sin—a controversy that helped spark the Reformation.
