We have found and interesting book on the history of healing and the Church of God. The title is “Who Healeth All Thy Diseases: Health, Healing, and Holiness in the Church of God Reformation Movement” (Revitalization: Explorations in World Christian Movements Pentecostal and Charismatic Studies) by Michael S. Stephens (Jul 7, 2008) One of the things this book mentions is a link between E. E. Byrum and F. F. Bosworth which we were previously unaware of.
Unfortunately our distributor does not carry this book but Amazon has limited quantities if you are interested in following up on this topic.
