Presbyter
Saint Phlegon was born on 28 March 1871 in the village of Karyaevo, Yaroslavl Province. After completing his studies at the Theological Seminary, he became a teacher at a parish school and was later ordained to the priesthood. He served in several churches, including the Church of St. Nicholas in Yaroslavl, where he devoted himself to preaching the Gospel. During the First World War, he faithfully fulfilled his pastoral ministry in military hospitals. In 1915, he was appointed to the Church of the Holy Great Martyr Demetrius of Thessaloniki and was awarded a gold pectoral cross in recognition of his service.
On 7 September 1929, during the persecution of the Russian Orthodox Church, he was arrested and charged with anti-Soviet activity and religious propaganda. He was sentenced to three years of exile. However, he was released on 10 November 1932. He subsequently settled on the border between the Moscow and Vladimir regions, where he worked for the railway.
He was arrested again on 4 December 1937 and imprisoned in Taganka Prison. He was accused of engaging in counter-revolutionary propaganda, but steadfastly maintained his innocence. On 9 December 1937, he was sentenced to ten years of imprisonment in a forced labour camp.
Saint Phlegon fell asleep in the Lord on 23 April 1938 in a labour camp in the Novosibirsk region. He was buried in an unmarked grave.
