Born in Rome, New York on May 12, 1880, Park attended the city schools of Syracuse and graduated from Syracuse University, where he was the captain of the football team in 1905. After graduation, he studied at the Reformed Presbyterian Theological Seminary from 1907 to 1910. Licensed by the Rochester Presbytery on May 4, 1909, he was ordained to the ministry by the Pittsburgh Presbytery and installed as pastor of the denomination's Parnassus congregation on 11 November 1910. Park remained pastor of the congregation until August 28, 1922, when he resigned to serve at Geneva. While Park was the head of the history department at Geneva, he was also a longtime sports coach: he coached the football team in 1922, the cross country team from 1926 to 1928, and the track team from 1929 to 1949. He was also the Dean of the College and the chairman of the Bible Department from 1949 until 1955. Park continued to serve his church, being chairman of various committees and sitting on the boards of both Geneva College and RPTS. In 1929, he was elected the church history professor at RPTS. Park continued his schooling after beginning his professorship, earning an M.A. from the University of Pittsburgh in 1924 and eventually earning a PhD. He was recognized for his accomplishments later in life, being elected the Moderator of the Synod of the RPCNA in 1951, and receiving a D.D. from Syracuse University in 1934. Beginning in 1929 and continuing until his death, Park spent his summers pastoring at the Reformed Presbyterian congregation in Cornwallis, Nova Scotia.
