Cyril Lucaris

Cyril Lucaris born Constantine Lukaris or Loucaris (1572–1638, Greek: Κύριλλος Λούκαρις) was a Greek prelate and theologian, and a native of Candia, Crete (then under the Republic of Venice). He later became the Greek Patriarch of Alexandria as Cyril III and Ecumenical Patriarch of Constantinople as Cyril I. Loukaris strove for a reform of the Eastern Orthodox Church along Protestant and Calvinist lines. Attempts to bring Calvinism into the Orthodox Church were rejected, and Cyril's actions and motivations remain a matter of debate among the Orthodox.
