Homer Hailey was an American preacher in the churches of Christ in the 20th century, a professor at Abilene Christian University and Florida College, and the author of at least fifteen theological books. He was well known for his general biblical knowledge, especially the Old Testament. Hailey and the churches of Christ are the topics of the book The Churches of Christ in the 20th Century: Homer Hailey's Personal Journey of Faith by David Edwin Harrell, Jr. Most of Hailey's books are still in print. Audio recordings of his sermons and classes are available through TruthOnDisc.Net Homer Hailey was born outside Marshall in Harrison County in East Texas, the oldest child of Robert Thomas Hailey and the former Mamie Collins. His brothers and sisters were Rob, Ruth, Jack, Roy, and Mary Ida. On December 20, 1930, in Abilene, Texas, he married the former Lois Estelle Manly. They had five children: Roma Luceil, Mary Lois, Homer Rob, Charles Dennis, and Carol Ann. After Lois' death, he married the former Widna Neeley Kirby on October 4, 1955. Hailey died in 2000 at the age of ninety-seven in Tucson, Arizona. In 2000, Harrell, a professor emeritus of religion at Auburn University in Auburn, Alabama, published The Churches of Christ in the Twentieth Century: Homer Hailey’s Personal Journey of Faith. Harrell alternates chapters between an historical look at an issue or conflict within the first century of the Churches of Christ and the way in which Homer Hailey responded to that issue or conflict. The plain-spoken Hailey who had memorized nearly every verse in the Bible became Harrell's touchstone for the history of the churches of Christ in the 20th century. In 2001, Alvin Jennings, owner of Star Bible Publications and a student in Homer Hailey's 'Denominational Doctrines' class in 1949, preserved Hailey's polemic style class notes which gave his reasons that led him out of the churches which offer instrumental music. Hailey reviewed the old hectograph outlines and refined them for publication. As a child, Homer Hailey lived outside Marshall, Texas. The nightLady Bird Taylor - the futureFirst Lady - was born, her brothers spent the night at the Hailey house, with their friends Homer and Rob.
