Jerald and Sandra Tanner became some of the most beloved and despised people ever to research the historical roots of the Mormon religion. In this series of episodes with Sandra (Jerald is now home with Jesus) she shares their story. In this fourth episode she chronicles the rise of Utah Lighthouse Ministry from its humble beginnings as Modern Microfilm, creating mimeographed sheets of LDS source material for doubting family and friends, to eventually printing the epic length volume Mormonism: Shadow or Reality?  Along the way Sandra and Jerald connected with Wes Walters, and were influential in the lives of historians like Dan Vogel, Michael Marquardt, and Brent Metcalf, creating a new wave of Mormon historical research that started a "cold war" of between LDS and non-LDS historians of Mormonism to determine its true origins and how that story should be told. Their faith and trust in Jesus to provide for their family was rewarded time and again with just what they needed to keep moving forward.
