 In Catholic, Eastern Orthodox, Anglican, Oriental Orthodox, and Lutheran 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.While the English word "saint" originated in Christianity, historians of religion now use the appellation "in a more general way to refer to the state of special holiness that many religions attribute to certain people", with the Jewish tzadik, the Islamic walī, the Hindu rishi or Sikh guru, the Shintoist kami, and the Buddhist arhat or bodhisattva also being referred to as saints.Depending on the religion, saints are recognized either by official ecclesiastical declaration, as in the Catholic faith, or by popular acclamation (see folk saint).
