papal infallibility

Pontiff's unerring authority

Papal infallibility is the Catholic doctrine that the Pope, when speaking officially on matters of faith and morals, cannot err.

The doctrine applies only to formal declarations made "ex cathedra" (from the chair), not to everyday statements or personal opinions.

It was formally defined in 1870, though rarely invoked since: The Pope has used papal infallibility only once since Vatican I.
