heresiarch. He was archimandrite of a monastery at Constantinople. His opposition to Nestorius in 448 led to his being accused of the opposite heresy of confounding the two natures in Christ (See Christology); he was deposed by Flavian, Abp. of Constantinople, acquitted at the Latrocinium (449), and deposed and exiled at the Council of Chalcedon (451). Eutyches affirmed that there was only one ‘nature’ in the incarnate Christ and denied that His manhood was consubstantial with ours, a view which was held to be incompatible with our redemption through Him. While the Oriental Orthodox Churches share his language about ‘one nature’, they explicitly condemned him for his denial that Christ's human nature was consubstantial with ours.
