COURTECUISSE (BRIÈVECUISSE, Brevicoxa), JEAN. - Born at Halenie (Orne) around 1353, he was one of the most active ecclesiastics during the Western Schism, holding benefices in various dioceses; he was a renowned orator and taught at the Collège de Navarre in Paris (doctor sublimis), where he also served as rector. Almoner to the king, member of the Grand Council, and chancellor of the Chapter of Paris, he maintained relations with Benedict XIII and Gregory XII, working to reconcile the schism. Elected Bishop of Paris on 27 December 1420, he was unable to remain in office due to political factions and was transferred to Geneva by the Pope on 12 June 1422; he died at the age of seventy on 4 March 1423.
Of his numerous unpublished works, only the *Tractatus de Fide et Ecclesia, Romano Pontifice et Concilio generali* has been published, appearing in the *Opera omnia* of Gerson (I, Antwerp 1706, cols. 805-903), where he teaches that the Pope may err, but not the Church gathered in an ecumenical council, and that the latter has the right to judge the Pope in cases of heresy.
