Eutychius, Ecumenical Patriarch of Constantinople dies in Constantinople.
Eutychius served as Patriarch at two different times, being deposed and exiled due to theological and political disagreements. In 564, during his first Patriarchy, he came into conflict with Justinian the Great when the emperor adopted the heretical belief that Jesus' body was incorruptible and could experience no physical pain.
Because Eutychius wouldn't subscribe to this doctrine, Justinian had him arrested and exiled. After 12 years and the death of his replacement, the people of Constantinople demand Eutychius' return. The new emperor, Justin II, agrees. Before his death, though, Eutychius starts to adopt a heresy himself: the belief that after the resurrection the nature of the human body changes.
