"For over a century Benjamin Hardin Irwin has been a shadowy figure in the history of late nineteenth century Holiness movements and early twentieth century Pentecostal movements in the United States. From writers such as J.H. King, we knew that in 1900 Irwin ignominiously left the movement he birthed, the Fire- Baptized Holiness Church. But beyond that, very little was known of the life of this enigmatic man. However, after years of research bolstered by the accessibility of numerous sources otherwise unknown and inaccessible, noted Pentecostal scholars Dr. Vinson Synan and Dr. Dan Woods have provided a rich study of Irwin and his writings."
