'''Pentecostalism''' is a spiritual [[Christian]] revivalist movement that began within [[Protestantism]]. It emphasizes gifts of the Holy Spirit, and has experienced explosive growth for the past half-century. The membership is young and fast-growing. Combined, the Pentecostals (in separate denominations) and [[Charismatic movement|charismatics ]] (inside other denominations) add up to very large numbers. The statistics are highly inexact but the combined total is perhaps one Christian in ten, worldwide.
Although Pentecostalism is descended from [[Methodism]] and the Methodist [[Holiness Movement]], many do not consider it as "Protestant." It has gained some acceptance by the [[Roman Catholic Church]] in the [[Second Vatican Council]].
