Your trust in the news media seems really naive. Have you actually watched the news in recent years? Media was rather unprofessional around the turn of the 20th century compared to later standards, say the 1970s or 19980s, even. Of course, it is not very professional these days, much of it. Glitzy and high tech, but professional standards have dropped significantly.If the amazing things that are claimed went on there really happened it would've been all over the papers.
The way they spin politics, do you trust news people with spiritual truth, or anything having to do with religion?
Be that as it may, I asked a couple of Pentecostal scholars, including the founder of the field of Pentecostal history, about this man's book and they hadn't heard of it or the claims therein. One did not know of historical documentation of the claims, and another had never heard of the book. He was rather elderly, the founder of the field of Pentecostal history as an academic discipline.
That doesn't prove some of the testimonies aren't accurate. Not showing up in the newspaper certainly does not.
