About Cyril Lucaris
Cyril Lucaris (born November 13, 1572) was a prominent Greek prelate and theologian who served as Patriarch of Alexandria and later as Ecumenical Patriarch of Constantinople. Born in Candia (Heraklion) on Crete, then part of the Republic of Venice, his early life and education took him across Europe, including studies in Venice, Padua, Wittenberg, and Geneva. It was in Geneva that he was significantly influenced by Calvinism and the Reformed faith, developing a critical stance towards Roman Catholicism.
Life and Ministry
Ordained in Constantinople, Cyril Lucaris was dispatched to the Polish–Lithuanian Commonwealth to counter the Union of Brest. He spent six years as a professor at the Orthodox academy in Vilnius. In 1601, at the age of twenty-nine, he was installed as Patriarch of Alexandria, a position he held for two decades. During this time, his theological views increasingly aligned with Protestant Reformation doctrines. He corresponded with prominent figures like Marco Antonio de Dominis and expressed his conviction that the Reformed faith was more aligned with God's Word.
Facing pressure from Turkish oppression and the proselytizing efforts of Jesuit missionaries, Cyril Lucaris recognized a need to strengthen Orthodox education. He founded a theological seminary at Mount Athos, known as the Athoniada school. In 1627, he authorized the establishment of the first Greek language printing press in Constantinople, which unfortunately was closed a year later due to French protests over its anti-Catholic publications. He also sponsored Maximos of Gallipoli's translation of the New Testament into Modern Greek.
Theological Reforms and Controversy
Cyril Lucaris's most significant and controversial undertaking was his attempt to reform the Eastern Orthodox Church along Calvinistic lines. He supported young Greek theologians in their studies at European universities and, in 1629, published his "Confessio" (Confession of Faith). This work presented Calvinist doctrine, though it was carefully accommodated to Orthodox language and creeds. The "Confessio" sparked a major theological controversy, leading to criticisms at synods in Constantinople (1638) and Iași (1642), and culminating in the Synod of Jerusalem (1672), which condemned Calvinistic doctrines. However, the authenticity and authorship of the "Confessio" have been debated, with some scholars arguing that the evidence for Lucaris's authorship is overwhelming, including a manuscript in his handwriting.
Lucaris also had a positive disposition towards the Church of England, maintaining correspondence with the Archbishops of Canterbury. Many valuable manuscripts collected by him and his contemporaries, like Metrophanes Kritopoulos, now form part of the Patriarchal Library.
Politics and Martyrdom
Cyril Lucaris's tenure was marked by political instability. He was temporarily deposed and banished multiple times, often at the instigation of his Orthodox opponents and ambassadors from France and Austria, while receiving support from the Dutch and English ambassadors. His final downfall occurred when the Ottoman Sultan Murad IV, preparing for war, had him accused of inciting unrest among the Cossacks. To prevent trouble during his absence, the Sultan ordered Cyril Lucaris to be strangled by Janissaries on June 27, 1638, aboard a ship in the Bosporus. His body was cast into the sea but was recovered and buried in Nicomedia. His remains were later brought back to Constantinople.
Legacy and Veneration
Cyril Lucaris was honored as a saint and martyr shortly after his death. In modern times, the Holy Synod of the Patriarchate of Alexandria glorified Loukaris on October 6, 2009, and he is commemorated on June 27. The debate surrounding his theological views and the authenticity of his "Confessio" continues among scholars, but his martyrdom has secured his place in Orthodox veneration.
