Confession against iconoclasm
Niketas belonged to the generation of hierarchs who resisted the revived iconoclasm under Leo V the Armenian (reigned 813-820). Sources record that he was exiled for the confession of the faith, and some traditions associate his exile with that of his brother Ignatios, who is commemorated together with him. The Canon for his liturgical service was composed by the priest Joseph of Constantinople, in which his brother Saint Ignatius is also remembered.
