|an extraordinary or unusual thing, person, or event; an exceptional example or instance.|
|a children's mummer's parade, as on the Fourth of July, with prizes for the best costumes.|
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.”
