Preceded by eleven historiographic charts, "Chronological Theology" addresses broad lines of theological innovation and heresy within Western Christianity. It originated with the chronological timelines as told by three noted Protestant scholars: -Johannes Sleidan, The Key of History or the Four Chief Monarchies (Strasbourg, 1556) -Jean de Hainault, State of the Church, with Discourses from the Time of the Apostles (Geneva, 1562) -Lorraine Boettner, Roman Catholicism (Philipsburg, NJ, 1962) Their lists of chronological developments are enlarged by primary and secondary source material, along with a biblical analysis of the developments as they takes place. The result is a linear documentary of the ebb and flow of theology over two millennia of Western Christianity.
