ex cathedra

[(eks kuh-thee-druh)]

Descriptive term for an official pronouncement from the pope. Ex cathedra is Latin for “from the chair.” Roman Catholics believe that the pope speaks infallibly when speaking ex cathedra on questions of faith or morals, such as when Pope Pius XII declared in 1950 that Mary, the mother of Jesus, was physically taken up to heaven after her death.

Note

Figuratively, any authoritative pronouncement may be called “ex cathedra.”
