Eutyches (Greek: Εὐτυχής; c. 380 – c. 456) was a presbyter and archimandrite at Constantinople. He first came to notice in 431 at the First Council of Ephesus, for his vehement opposition to the teachings of Nestorius; his condemnation of Nestorianism as heresy led him to an equally extreme, although opposite view, which precipitated his being denounced as a heretic himself.
Eutyches was an archimandrite of a monastery outside the walls of Constantinople, where he ruled over three hundred monks. He was much respected and godfather to Chrysaphius, an influential eunuch at the court of Theodosius II.
The Archbishop of Constantinople, Nestorius, having asserted that Mary ought not to be referred to as the "Mother of God" (Theotokos in Greek, literally "God-bearer"), was denounced as a heretic; in combating this assertion of Patriarch Nestorius, Eutyches declared that Christ was "a fusion of human and divine elements", causing his own denunciation as a heretic twenty years after the First Council of Ephesus at the 451 AD Council of Chalcedon.
According to Nestorius, all the human experiences and attributes of Christ are to be assigned to 'the man', as a distinct personal subject from God the Word, though united to God the Word from the moment of his conception. In opposition to this, Eutyches inverted the assertion to the opposite extreme, asserting that human nature and divine nature were combined into the single nature of Christ without any alteration, absorption or confusion: that of the incarnate Word. Although this accorded with the later teaching of Cyril of Alexandria, Eutyches went beyond Cyril in denying that Christ was 'consubstantial with us men', by which he did not intend to deny Christ's full manhood, but to stress his uniqueness.
Eutyches denied that Christ's humanity was limited or incomplete, which some were led to believe was similar to the Alexandrine doctrine (this, however, is strongly rejected by the Coptic church that sees Eutyches a heretic), but the energy and imprudence with which he asserted his opinions led to his being misunderstood. He was accused of heresy by Domnus II of Antioch and Eusebius, bishop of Dorylaeum, at a synod presided over by Flavian at Constantinople in 448. His explanations deemed unsatisfactory, the council deposed him from his priestly office and excommunicated him.
In 449, however, at the Second Council of Ephesus convened by Dioscorus of Alexandria who was under the impression that Eutyches had renounced the false belief of Monophysitism, overawed by the presence of a large number of Egyptian monks, not only was Eutyches reinstated to his office, but Eusebius, Domnus and Flavian, his chief opponents, were deposed. This judgment is the more interesting as being in distinct conflict with the opinion of the bishop of Rome—Leo—who, departing from the policy of his predecessor Celestine, had written very strongly to Flavian in support of the doctrine of the two natures and one person.
Meanwhile, the emperor Theodosius II died, and Pulcheria and Marcian who succeeded, summoned, in October 451, a council (the fourth ecumenical) which met at Chalcedon and that Dioscorus was not allowed to attend and at which he was condemned. There the synod of Ephesus was declared to have been a "robber synod" with claims that Dioscorus had threatened the bishops with death if they did not agree with him. Its proceedings were annulled, and, in accordance with the more miaphysite strand in the teaching of Cyril of Alexandria, it was declared that the two natures are united in Christ (without any alteration, absorption or confusion) and 'come together to form one person and one hypostasis'. Eutyches died in exile, but of his later life nothing is known.
Those who did not approve of the Chalcedonian Council were later accused of being 'Monophysites' and are nowadays known as 'Oriental Orthodox', including the Coptic Church, the Armenian Orthodox Church, and the Syrian Orthodox Church. They were wrongfully accused of agreeing with Eutyches about 'one nature' in Christ that rejected Christ's dual consubstantiality (with the Father and with us men); however, Oriental Orthodox churches prefer to be called 'Miaphysites' and are against the teachings of Eutyches. This was confirmed in May 1973 when the late Coptic pope, Shenouda III, visited Rome and penned a Christological statement with pope Paul VI.
His memory was kept alive by the Chalcedonians, who until recently used the term 'Eutychean' as a pejorative description of the non-Chalcedonians who in their turn accused the Chalcedonians of being Nestorians and dyophysite.
