Georges Vasilievich Florovsky (Russian: Гео́ргий Васи́льевич Флоро́вский; September 9 [O.S. August 28], 1893 – August 11, 1979) was an Orthodox Christian priest, theologian, historian and ecumenist. Born in Odessa, in the Russian Empire, he spent his working life in Paris (1920–1949) and New York (1949–1979). With Sergei Bulgakov, Vladimir Lossky, Justin Popović and Dumitru Stăniloae he was one of the more influential Orthodox Christian theologians of the mid-20th century. He was particularly concerned that modern Christian theology might receive inspiration from the lively intellectual debates of the patristic traditions of the undivided Church rather than from later Scholastic or Reformation categories of thought.
Georgiy Vasilievich Florovsky was born in Russian Empire on 9 September 1893 at Odessa (then in the Kherson Governorate of the Russian Empire), as the fourth child of an Orthodox Christian priest. Raised in an erudite environment, he learned English, German, French, Latin, Greek, and Hebrew while a schoolboy, and at eighteen he started to study philosophy and history. He graduated from the University of Odessa in 1916.
In 1919 Florovsky began to teach at the University of Odessa; but in 1920 his family was forced to leave Russia. Florovsky realized at that time that there would be no return for him, because Marxism did not accept the history and philosophy he taught. He was part of the emigration of Russian intelligentsia, which also included Nikolai Berdyaev, Sergei Bulgakov, Nicholas Lossky and his son Vladimir Lossky, Alexander Schmemann, and John Meyendorff (the last two of whom would follow him in the USA as Dean of Saint Vladimir's Orthodox Theological Seminary, New York).
In the 1920s Florovsky had a personal and vocational friendship with the existentialist philosopher Nikolai Berdyaev, but the two became distanced later, through Berdyaev's not understanding Florovsky's ordination to the presbyterate (1932), and because of the critical attitude to Berdyaev's philosophy of religion expressed in Florovsky's Ways of Russian Theology (1937).
In 1924 Florovsky received his M.A. in Prague. In 1925 he became professor of patristics at the St. Serge Institute of Orthodox Theology in Paris. In this subject he found his vocation. The lively debates of the thinkers of the early Church became for him a benchmark for Christian theology and exegesis, as well as a base for his critique of the ecumenical movement, and despite his not having earned an academic degree in theology (he was later awarded several honorary degrees) he would spend the rest of his life teaching at theological institutions. In 1932 Florovsky was ordained priest of the Orthodox Church. During the 1930s he undertook extensive research in European libraries and published in Russian valuable patristic studies, such as his book on 'Eastern fathers of the fourth century' (1931) and 'The Byzantine fathers fifth to eighth centuries' (1933). These were followed by his magnum opus, Ways of Russian Theology (1937). In this work he questioned the Western-European Christian influences of scholasticism, pietism, and idealism on Orthodox, and especially Russian, Christian theology, and called for its reformulation in the light of patristic writings. The work was received with enthusiasm or condemnation—there was no neutral attitude to it among Russian émigrés. One of his most prominent critics was Nikolai Berdyaev. Florovsky remained professor of patristics at the Institute until 1939, and from 1939 to 1948 taught there as professor of dogmatics.
In 1949 Florovsky moved to the United States of America, to take a position as Dean of Saint Vladimir's Orthodox Theological Seminary in New York City. There his development of the curriculum led to the Board of Regents of the University of the State of New York granting the Seminary an Absolute Charter in 1953.
In 1955 Florovsky was asked by his synod overseers to "lay down the deanship." He became a professor of divinity at Harvard University, and ended his academic years as a professor at Princeton University.
He died on 11 August 1979.
