In the summer of 1907 Gaston Barnabas Cashwell journeyed to Birmingham, Alabama to share the Pentecostal experience that he had recently received at the Storied Azusa Street Mission in Los Angeles. Cashwell, who now is seen as “the Apostle of Pentecost to the South,” was a member of the Pentecostal Holiness Church of North Carolina. In January 1907 he brought Pentecost to the South in Dunn, North Carolina in what is now known as “Azusa Street East.”
After this he made a six-month whirlwind tour of the South attracting large crowds to his Pentecostal message. One of these trips was to Birmingham, Alabama in the summer of 1907 where many people came to learn about the new tongues attested baptism in the Holy Spirit. Coming to hear him were important future leaders of the Pentecostal movement. Among these were: A.J. Tomlinson, General Overseer of the Church of God, and M.M. Pinson and H. G. Rogers who later became two of the founding fathers of the Assemblies of God in 1914. Another was O.N. Todd, Sr., who was pastor of the Birmingham Fire-Baptized Holiness Church, which after 1911 was known as the First Pentecostal Holiness Church of Birmingham.
In January 1908, Cashwell preached at the General Assembly of the Church of God in Cleveland, Tennessee where Tomlinson received the Pentecostal experience. After this the Church of God became a fully Pentecostal denomination.The Birmingham visit of Cashwell in 1907 was a historic turning point in bringing Pentecost to the Southern states.
