Penance, stemming from contrition for sin, represents both a moral virtue and a sacramental practice within Christianity, especially in Catholic traditions. It connects inner repentance with outward acts of atonement, such as fasting or prayer, intended to restore spiritual harmony. Scholars such as Henry Charles Lea associated penance with judicial retribution, while Cornelius à Lapide highlighted the proportionality of suffering relative to the seriousness of the sin.
Arthur Stanley Turberville emphasized its function as a visible symbol of genuine repentance, and Franz Hunolt cast doubt on its strictness for those without guilt. Bringing these viewpoints together, penance appears as a dynamic interaction between personal regret and communal healing, embodying both individual salvation and the maintenance of social moral order.
