Ninety-five Theses [SEP] Content
The iconic first thesis states, "When our Lord and Master Jesus Christ said, 'Repent,' he willed the entire life of believers to be one of repentance." In the first few theses Luther develops the idea of repentance as the Christian's inner struggle with sin rather than the external system of sacramental confession. Theses 5–7 then state that the pope can only release people from the punishments he has administered himself or through the church's system of penance, not the guilt of sin. The pope can only announce God's forgiveness of the guilt of sin in his name. In theses 14–29, Luther challenged common beliefs about purgatory.
