Under Elder Bellamy's leadership the building on Roosevelt Road was purchased, and God continuously added to the membership. In 1975, the saints marched into the present location at 502 S. Sixth Avenue, Maywood, Illinois. Christ Temple Church of the Apostolic Faith, Inc. became the regional location for many civic and religious entities, including the first home of the Midwest Apostolic Bible College, which is affiliated with the Pentecostal Churches of the Apostolic Faith (P.C.A.F.).
Elder Bellamy taught both public speaking I and II, and Pentecostal Doctrine I and II for many years. He was elected Vice Chairman of the Illinois State Council for approximately 14 years. Then, he was elected Council Chairman. He was elected chairman of the United Pastor's Alliance of the Pentecostal Churches of the Apostolic Faith (P.C.A.F.) and served until elevated to be a District Elder. He was then elected to be Chairman of the Board of District Elders, where he served faithfully until he was consecrated as Bishop on August 6, 1993. He received Honorary Doctorates in Divinity and Theology from Pentecostal Bible College in Tuskegee, Alabama. He served as Diocesan over the states of North Carolina and Hawaii.
Bishop Dr. John P. Bellamy, Sr. was an apologist for the Apostolic Doctrine. He began weekly radio broadcasts preaching the unadulterated Apostolic Doctrine. He believed in the laying on of hands. As a result of his humble ministry, God healed many sick and afflicted, blessed many financially, many souls were baptized in water in Jesus’ Name and filled with the Holy Spirit. He preached and taught the Word without compromise. He would often say, "It's Holiness or Hell", as well as “if you don't do right, hell is hot and eternity is long". The church grew with members from Maywood, the West and South sides of Chicago, and surrounding areas.
