Father Durbin was a man of tremendous personal, physical and spiritual strength. By the end of his nearly lifelong ministry he estimated that he had traveled more than half a million miles on horseback. Over time, Father Durbin developed a craggy appearance due to climatic vagaries. Through the course of his ministry he built at least fifteen churches. During the Civil War his priority was attending to the souls of both Union and Confederate soldiers. He was a saintly man by most definitions.
