Archbishop Luka (Luke, Russian: arhiepískop Luká, born Valentin Felixovich Voyno-Yasenetsky, Russian: Valentín Féliksovich Vóino-Yasenétskii; April 27/May 9, 1877 in Kerch – June 11, 1961, Simferopol) was an outstanding surgeon, the founder of purulent surgery, a spiritual writer, a bishop of Russian Orthodox Church, and an archbishop of Simferopol and of the Crimea since May 1946. He was a laureate of Stalin Prize in medicine in 1946.
His most important work in medicine is Purulent Surgery Essays, 1934. This is still a reference book and a manual for surgeons.
As a noticeable religious figure, he was subjected to political repressions and spent 11 years in internal exile. He was canonized in Russian Orthodox Church in 2000. His feast day is May 29/June 11 (Julian [Old] Calendar/Gregorian [New] Calendar).
Luka was born into a family of faithful parents but, according to his memoirs, did not receive a religious upbringing from his family. He apprehended the Christ's teaching by assiduous reading of the New Testament.
