John MacArthur comments:

In much of the world, the Charismatic Movement indiscriminately absorbs the pagan ideas of local false religions into its theology. For example, in Africa, a traditional obsession with witchdoctors, demonic spirits, and ancestor worship has been largely assimilated by Pentecostal churches there. The resulting hybrid calls itself “Christian” but is actually rooted in tribal paganism.
