Thank you vienne, very interesting stuff, it shows how those Religious movements in the late 1900's were able to start, and grow in some measure, quite easily.
A charismatic man with a different view on what the Bible is about usually heads them , though there were similar women, most fizzled out eventually, but 7th Day Adventists, Latter Day Saints, Christian Science, Russell's W.T etc, all survived.
A good business plan was needed to survive, it would seem.
It is amazing how long people stuck to such movements, not only because of the advances in Scientific knowledge, but also the advancing Biblical Scholarship which from the 19th Century gradually became much more sophisticated and indeed Scientific in approach, and showed the Bible gradually to be more and more questionable.
I presume the same techniques were used as those used by the JW org and the Mormons , SDA's etc. that of persuading the adherents that they alone had the "Truth" and counter messages were to be ignored.
Fascinating stuff ! Thank you for your work !!
