449 CE
A synod held in Constantinople condemns Eutyches on a charge of heresy; Flavian, bishop of Constantinople, deposes him from his position as archimandrite there.
Pope Leo, in his dogmatic "Tome to Flavian," condemns Eutyches’ denial of Christ's human nature.
Theodoret, accused in 448 by Cyril's successor, the politically powerful Dioscorus, of dividing Christ into two natures, is anathematized in 449 despite his insistence on the unity.
