Mary Lee (Harris) Cagle (12 September 1864 – 1955), sometimes called the Mother of Holiness in West Texas, was one of the first influential women and pastors in the early Church of the Nazarene.
The influence of this movement that the Harris church started in Milan quickly spread into Arkansas and Texas.
Upon Harris' death from tuberculosis, his wife took over his work with the assistance of a couple of other women in the church.
Near the close of the century, Sister Mary Lee moved her base of operations to Buffalo Gap, Texas, south of Abilene.
She and her husband organized twenty-eight churches, including congregations in Texas, New Mexico, and Wyoming.
