Demons and Tongues

First published in 1910, "Demons and Tongues" (AKA "Demons And Tongues: A Work of Christian Demonology") by Alma White is an interesting early 20th century look at the opinions of the Pillar of Fire movement in regards to the Pentecostal assembly and demonology twain with the same. With a quasi-eugenic approach and a focus on Revelation, this manuscript is at once interesting and perhaps dated in the christian body. 
Speaking of the goals of Satan, that old Devil of antiquity, and the way this being uses heresy, it shuns the very concept of speaking in tongues and relegates it to the depraved and demonic.
