Acephali
A Dictionary of Early Christian Biography [1]
Acephali (from ἀ and κεφαλή , those without a head or leader) is a term applied:—(1) To the bishops of the oecumenical council of Ephesus in 431, who refused to follow either St. Cyril or John of Antioch—the leaders of the two parties in the Nestorian controversy. (2) To a radical branch of Monophysites, who rejected not only the oecumenical council of Chalcedon in 451, but also the Henoticon of the emperor Zeno, issued in 482 to the Christians of Egypt, to unite the orthodox and the Monophysites. Peter Mongus, the Monophysite patriarch of Alexandria, subscribed this compromise [See Acacius (7)]; for this reason many of his party, especially among the monks, separated from him, and were called Acephali. They were condemned, under Justinian by a synod of Constantinople, 536, as schismatics, who sinned against the churches, the pope, and the emperor. Cf. Mansi, Conc. tom. viii. p. 891 sqq.; Harduin, Conc. tom. ii, 1203 sqq.; Walch, Ketzerhistorie, vol. vii.; Hefele, Conciliengeschichte , vol. ii. pp. 549, 744. (3) To the clerici vagi, i.e. clergymen belonging to no diocese (as in Isid. Hispal. de 0ffic. Eccl., the so-called Egbert's Excerpts, 160, and repeatedly in Carlovingian Councils: see Du Cange) [ D. C. A. art. VAGI Clerici]. (4) It is said to be used sometimes for αὐτοκέφαλοι . [ D. C. A. art. Autocephali.]

( Ἀ and Κεφαλή ), literally, those who have no chief. The term is applied to various classes of persons (see Biedermann, De Acephalis, Freiberg, 1751).
1. To those at the Council of Ephesus who refused to follow either St. Cyril or John of Antioch.
2. To certain heretics in the fifth century who denied, with Eutyches, the distinction of natures in Jesus Christ, and rejected the Council of Chalcedon. About the year 482 the Emperor Zeno endeavored to extinguish these religious dissensions by the publication of an edict of union, called Henoticon. The more moderate of both parties subscribed the decree, but the object was generally unsuccessful. The Monophysite patriarch of Alexandria was among those who signed the decree; which so greatly displeased many of his party that they separated from him, and were denominated Acephali, that is, without a head. (See Monophysites) and (See Henoticon). These Acephali were condemned in the synod of Constantinople, 536.
3. To bishops exempt from the ecclesiastical jurisdiction of their patriarch.
4. To the Flagellants (q.v.).
