For two years John Curran attended Providence College and then entered the Dominican Order at Saint Rose in Kentucky, where he made profession on September 11, 1927. He pursued his studies for the priesthood in River Forest, Somerset, and Washington, D.C., where he was ordained a Catholic priest on June 17, 1933. Shortly before World War II began, he entered the military service as an Army Chaplain and volunteered for duty in the Philippines, where he arrived in June 1941. He was captured during the fall of the Philippine Islands and suffered as a Prisoner of War until his release in 1945. Early in October 1945, Father Curran was en route home when he suffered serious injuries in an auto accident which, in his weakened condition, required long hospitalization and left him crippled for life. In 1947, he returned to serve the people in Ponchatoula and Pass Manchac where he built its small church. As his health declined, he was appointed chaplain to Saint Dominic’s Hospital in Jackson, Mississippi, where he served for seventeen years in semi-retirement until his death.
