In that same year that the United Pentecostal church was formed, the Midwestern District Council was established in 1945 in St. Louis, Missouri. Although there were churches already established in the Midwest; there was no established council. As stated earlier, in the Pentecostal Assemblies of the World, Incorporated history, when the organization met in St. Louis, Missouri in 1918 with Minister J.J. Frazee conducting a business meeting, Elder Robert C. Lawson was there preaching the Oneness Doctrine at Central Baptist Church (one of the oldest churches in St. Louis). A small group of people accepted the message and decided to establish an assembly in St. Louis.

Although this was one of the meetings recognized in history, the PAW, Inc. also had another meeting in St. Louis where Glenn A. Cook brought the message in January 1915 after he met J. Roswell Flowers in Indianapolis, Indiana in 1907. He did not accept the message at first and even warned G.T. Haywood to refrain from meeting with Flowers but Haywood had already been re-baptized. But the sole purpose of the meeting January 17-27, 1918 was to discuss the merger with G.A. of A.A (General Assemblies of the Apostolic Assemblies). Thus, they held a special council in St. Louis, Missouri to discuss the merger on Tuesday, January 22, 1918. During the time of its meeting, the G.A. of A.A. was only approximately 2 years old because they held their 1st meeting/convocation in Eureka Springs, Arkansas on Thursday, December 28, 2016 until Friday, January 5, 1917. Their officers at this time were Chairman: Daniel C.O. Opperman (Eureka Springs, AR), Secretary: Lee Floyd, Credentials Committee: Howard A. Goss (Hot Springs, AR), and Member of Credentials Committee: H.G. Rodgers (Stuttgart, AR).
