d. c.367. Intellectual leader of Anomoean* heretics. A Christian tutor to Julian, later the “open-minded” emperor, Aetius was exiled in 358 by Constantius II for having unwelcome contacts at court and for opposition to the Homoiousion doctrine. In 360 he was banished for denying that God and the Son are in any way alike. Recalled in 362 by Julian, he helped the Anomoeans form a distinct group. In his Syntagmation Aetius teaches that the uncreated God and his offspring can be neither identical nor alike. Logic forbids someone transcendent submitting to change or being located in time. Nothing can be two things in essence. God is entirely uncaused, absolute, and indivisible; the Son is entirely caused and relative. They must be unlike one another (anomoios).
