EX CATHEDRA

The term commonly applied to the special and explicit exercise of papal infallibility. When the Pope speaks from the chair (cathedra) of authority, as visible head of all Christians, his teaching is not dependent on the consent of the Church and is irreformable. (Etym. Latin ex cathedra, from the chair.)
