Acephaloi - Coptic Wiki


Extremist anti-Chalcedonians in Egypt who refused to recognize the Alexandrian who accepted the HENOTICON. They first appear in in 482 as who MONGUS’s rapprochement with Constantinople (Zacharias Rhetor Historia ecclesiastica 6. 2). Their name denoted their community of purpose without the need of a personal leader, and least of all a Henoticist patriarch (see Leontius of Byzantium, De sectis 5, col. 1230). It is possible that these dissidents adopted the name of other irreconcilables who after the Formula of Reunion in April 433 rejected both CYRIL I and JOHN OF ANTIOCH (see Liberatus of Carthage Breviarium 9. 41).

At the end of the ACACIAN SCHISM, “Acephaloi” was used as a term of abuse by the Jerusalem Chalcedonians against SEVERUS OF ANTIOCH and his followers (Sacrorum collectio, Vol. 8, col. 1085, recording popular outcries when John, the patriarch of Jerusalem [516-524], visited the principal at Tyre on 16 September 518). In 520, a petition to Emperor Justin from “the clerics and abbots and landowners of the province of Secunda, and representatives from the patriarchates of Antioch and Jerusalem associated “acephaloi’ with “Eutychians’ and others whose excommunication they demanded” (Collectio Avellana 232a, p. 704).

The Acephaloi were condemned as a sect by the in June 536 (Sacrorum Collectio, Vol. 8, col. 891). They continued to exist when THEODORUS was consecrated Monophysite patriarch of in the summer of 575 (Severus, of the , 5, p. 474). The clear separation between Chalcedonians and Monophysites in Egypt after the reestablishment of the Chalcedonians’ patriarchate in 537 robbed the Acephaloi of most of their purpose, but they lingered on into times.
