In Anglican, Roman Catholic, Eastern Orthodox, Lutheran, and Oriental Orthodox doctrine, all of their faithful deceased in Heaven are considered to be saints, but some are considered worthy of greater honor or emulation; official ecclesiastical recognition, and consequently veneration, is given to some saints through the process of canonization in the Catholic Church or glorification in the Eastern Orthodox Church., Peter the Great, Peter I or Peter Alexeyevich (  ) ruled the Tsardom of Russia and later the Russian Empire from 7 May (O.S. 27 April) 1682 until his death, jointly ruling before 1696 with his elder half-brother, Ivan V.
