 The attempted accommodation by Fausto Sozzini only precipitated matters; tried as an innovator, Dávid died in prison at the Fortress of Déva (1579).The "cultus" of Christ became an established usage of the Church; it is recognized in the 1837 edition of the official hymnal, but removed in later editions.The term "unitarius" made its first documentary appearance, "unitaria religio", in a decree of the Diet of Lécfalva (1600); though it was not officially adopted by the Church until 1638.
