In 1905, Fr. E. F. Callahan wrote to Bishop Thomas Byrne, explaining why Harriman would be a good permanent center for the East Tennessee Catholic Missions.
One of the first Roman Catholic priests to minister in East Tennessee was Fr. Emmanuel Francis Callahan. Fr. Callahan was ordained June 29, 1897 and spent many years serving the missions of East Tennessee. These words from his diary describe what life was like for some of the first Catholics of the area. He and his horse Rebel lived quite a different life than we modern day priests.
