Canonical and church administrative aspects of the dispute about the prerogatives of the metropolitans of Nicaea and Nicomedia at the council of Chalcedon

Introduction. On October 30, 451, during the 4th Ecumenical Council in Chalcedon, the dispute between Metropolitan Eunomius of Nicomedia and Metropolitan Anastasius of Nicaea was considered. Eunomius believed that his rights as the metropolitan of the entire province of Bithynia, in regard to ordinations, were violated by Anastasius of Nicaea, who had deposed a number of clerics of the city of Vasilinopolis. Information about this lawsuit is taken from the published acts of the 14th session of the Chalcedon Council.
