““In the 1970s, the Russian Orthodox hieromonk Fr. Seraphim Rose famously said that he believed that there was a spirit in the Charismatic movement (which was then having a small impact in a handful of places in Orthodoxy), but that he believed that it was not the Holy Spirit. That is, he suggested that its origins were demonic: The “charismatic” texts themselves make it quite clear that what is involved in these experiences—when they are genuine and not merely the product of suggestion—is not merely the development of some mediumistic ability, but actual possession by a spirit. These people would seem to be correct in calling themselves “spirit-filled”—but it is certainly not the Holy Spirit with which they are filled! (Fr. Seraphim Rose, Orthodoxy and the Religion of the Future, 157)””
