It has its presence in many countries and it is one of the fastest-growing denominations in the world. After the death of founder Pa Josiah Akindayomi in 1980, Pastor E.A. Adeboye became its General Overseer in 1981. Adeboye Erra has witnessed many reforms that have led to the massive growth of the church. This paper examined the similarities between Luther's Reformation and that of Adeboye in RCCG. It makes use of the historical method and interviews with some long-standing members of the church. Findings show that Adeboye brought in some reforms that led to the growth of the church. For instance, he changed the liturgy of the church from its original African indigenous model to a Pentecostal genre. He created model parishes and allowed the ordination of women. Adeboye's belief resonates with Luther's belief in the priesthood of all believers as against the Catholic stand on the theory of two estates. The work postulates that reformation should not be seen as an invent of the 16th century but an on-going process in many churches. The paper recommends that Christian denominations should not be dogmatic but receptive to changes that will make people amenable to the without compromising bible standards.ReformationRedeemed Christian church of GodGrowthPentecostals.Article
