Diomid (Russian: Диомид), born 24 June 1961 in Kadievka, Ukrainian SSR as Sergey Ivanovich Dzyuban (Сергей Иванович Дзюбан) is a former bishop of the Russian Orthodox Church. He was the bishop of Anadyr and Chukotka from August 2000 to June 2008. Diomid is known for his views condemning ecumenism, taxpayer ID, cell phones, passports, vaccination and globalisation. He believes that the leaders of the Russian Orthodox Church have "departed from the purity of the Orthodoxal dogma" in its support of the Russian government and of democracy, as well as its ecumenism with other confessions.
