Our father among the saints Gregory V of Constantinople was the 234th Patriarch of Constantinople. He served as patriarch for three separate periods at the turn of the eighteenth and nineteenth centuries and was martyred during the Greek War of Independence. He was glorified as a saint by the Church of Greece in 1921 and is commemorated as an Ethnomartyr (Greek: Εθνομάρτυρας). He is remembered on April 10.
