From officer to priest
Born in 1856, Leonid Chichagov came from a family long associated with Russian military service; he trained at the Corps of Pages and the Artillery Academy and entered the army as an officer. During the Russo-Turkish War of 1877–1878 he saw heavy fighting and was decorated for bravery, earning the Cross of St. George at Plevna along with several foreign honors.
His acquaintance with John of Kronstadt, who became his spiritual director, drew him toward the Church. In 1890 he resigned his commission and settled in Moscow, where he studied theology, and in 1893 he was ordained first a deacon and then a priest. After the death of his wife in 1895 he embraced monasticism, taking the name Seraphim.
