Damnatio memoriae in the Christian Church in the West until the Great Schism (1054)

Using two examples: the condemnation of Theodore of Mopsuestia, Theodoret of Cyrus, and Ibas of Edessa at the Fifth Ecumenical Council (553) and the acceptance of the decisions of that council in Rome - a little later - by Pope Vigilius; and the condemnation of Pope Formosius (897), by analyzing the historical circumstances in which the described events take place, the application of the principle of damnatio memoriae will be investigated, and a conclusion will be drawn about how the Christian Church in the West treated controversial figures and their teachings and deeds in the period of the first millennium of Christ?s era. In this research, special attention will be directed to the political circumstances that influenced the decision-making on the implementation of the principle of damnatio memoriae in the Church, and the consequences of these events.
