 In 1989, Margaret Poloma noted that some pastors and even high ranking leaders within the Assemblies of God USA, a Pentecostal denomination, were critical of the practice.Slaying in the Spirit saw a resurgence during the 1960s and 1970s due to the influence of the charismatic movement, which disseminated Pentecostal beliefs and practices among mainline Protestants and Roman Catholics.During the 1980s, it experienced another surge in visibility due to the influence of John Wimber, an evangelical pastor and founder of the Vineyard Movement.
