A letter from Anatolius, Bishop of Constantinople, addressed to Leo the Great in 451 This letter was transmitted as part of Leo the Great's letter collection.


Although Leo was not present at the Council of Chalcedon, he played a prominent role from afar: he petitioned to have the council held, he wrote to it and sent his representatives. This council was called in response to the second council of Ephesus, which was convened in 449. At Ephesus, the delegates absolved Eutyches – an advocate of the docetist theory that the body of Christ was not made of human flesh – from heresy and deposed Flavian, the bishop of Constantinople. These decisions were overturned at Chalcedon two years later. Leo was a strong opponent of Eutyches and supporter of Flavian (see e.g. E05480). The Council of Chalcedon was convened in the church dedicated to the martyr Euphemia. See also E05462.
