In a Coptic fragment associated with the Acts of Peter, Peter “heals” and then “disables” his own daughter as a demonstration of God’s power at work in him. The following article will compare Peter’s speech with the ancient rhetorical form of the chreia. When placed alongside other traditions that describe the life of Peter, a consistent pattern of anti-healings emerges, in which a display of apostolic power harms another character in order to provide a lesson for those watching. Taken together, the rhetoric and themes of the pericope suggest that it was composed as a way of explaining a difficult saying that was attributed to Peter.
