John McIntosh attempts to describe more accurately and completely the spectrum of Evangelicalism (Anglican) that three successive principals of Moore Theological College appropriated and taught in the period. Each was an outstanding graduate of Oxford, Cambridge, and Dublin, respectively. The study traces the circumstances of their appointment and seeks to define the convictions they held -- against the background of challenges and changes to their Christian faith they faced in their day. A close examination of their published and unpublished literary oeuvre clears away misunderstandings and even misrepresentations of their thought and influence. In so doing it explains how it was that those Evangelicals in the diocese who adhered more closely to their Reformation tradition finally prevailed decisively over those who were Protestant but liberal.
