Furthermore, the manifestation not only changed from an unknown language to an angelic language but the reason for the gift changed. Initially, Pentecostalism saw the restoration of this gift as a means to evangelize the world supernaturally and quickly. Due to the various well-publicized failures on the missionary field, the manifestation shifted from missionary work to the individual's personal prayer life. After WWII America experienced a "Healing Revival" with various Pentecostal tent-revivalists.30 This revival marks the explosion of Pentecostal practices (primarily tongues, prophecy, healing, and deliverance from demons) into non-Pentecostal denominations referred to as the "Charismatic Renewal" movement.31
The use of the gift changed from a supernatural missionary tool into a private (me and Jesus) language. It changed from being seen as a missionary gift for ministers to something that all believers can posses and should practice. Tongues went from having to be translated in public ministry today where entire groups of people all speak in tongues at the same time with no translation expected.
The only "restoration" of these gifts back into the Church is through outright heretical teachers (Montanus and his disciples) and later questionable fringe sects (Camisards, Shaking Quakers, Holiness groups) or other non-Christian cult groups.37 The Shakers were America's first non-Christian Pentecostals and since their advent other non-Christian Bible-based cults practice speaking in tongues as part of their piety including the Latter Day Saints (Mormons), the Unification Church of the Holy Spirit (Moonies), the Way International, snake handling groups to cite a few."
