Athanasius of Nicomedia

Saint Athanasius of Nicomedia, Hieromartyr, was metropolitan of Nicomedia and received the crown of martyrdom in the year 1821, beside Patriarch Gregory V of Constantinople. He was one of the seven hierarchs put to death in the same circumstances: Eugenios of Anchialos, Joseph of Thessaloniki, Gregory of Derkoi, Dionysios of Ephesus, Dorotheos of Adrianople, Athanasios of Nicomedia and Ioannikios of Tarnovo.

On 15 July 2021, two hundred years after the martyrdom of Patriarch Gregory, the Holy Synod of the Church of Greece decided to include in the list of saints the other seven hierarchs as well, Athanasius among them. They are commemorated on 10 April (new style, the calendar of the Church of Greece), together with Patriarch Gregory.
