Azymites

(Lat. infermentarii, “unleavenders”). An Eastern (non-Armenian) Church term of reproach against the Western Church for the eucharistic use of unleavened bread. It furnished a pretext for the 1054 schism of East from West under Michael Cerularius.* The Council of Florence (1437) authorized (transubstantiationally) wheaten bread, leavened or unleavened. Modern Anglicans use either indifferently; other Protestants prefer leavened.
