The charismatic movement begins with the aoption of certain beliefs typical of those held by Pentecostal Christians — specifically what are known as the biblical charisms or spiritual gifts: glossolalia (speaking in tongues), prophesying, supernatural healing — by those within mainstream Protestant and Roman Catholic churches. Many charismatic Christians went on to form separate churches and denominations. The writings of John Fletcher were influential in beginning this movement, which was sparked by the Azusa Street Revival in California, which took place in 1906. Though charismatic theology finds its roots in the Wesleyan-Holiness tradition, charismatic Christians can now be found within numerous theological movements and in multiple denominations.
