Cyril Lucaris
Hieromartyr Cyril Lucaris or Loukaris (Greek: Κύριλλος Λούκαρις, 13 November 1572 – 27 June 1638), born Constantine Lucaris, 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. Lucaris 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.
Life
Cyril Lucaris was born in Candia, Crete on 13 November 1572, when the island was part of the Venetian Republic's maritime empire. In his youth he travelled through Europe, studying at Venice and the University of Padua, and at Geneva where he came under the influence of the reformed faith as represented by John Calvin. Lucaris pursued theological studies in Venice and Padua, Wittenberg and Geneva where he came under the influence of Calvinism and developed strong antipathy for Roman Catholicism.
