Gauvreau explores the persistence and development of the evangelical creed as the intellectual expression of Protestant religion which largely defined English-Canadian culture in the Victorian period. This popular theology, which linked Methodist and Presbyterian church colleges to the world of popular preaching, was based on the Bible not only as the foundation of personal piety but as a sacred record of human history: past, present, and future. Gauvreau shows that the evangelical creed proved flexible when faced with the challenges of Darwinian evolution, higher criticism, and other new intellectual currents, and that it remained central to the intellectual life of the churches. By accommodating those aspects of modern thought most compatible with evangelicalism and filtering out those more threatening, clergymen-professors such as Samuel Nelles, Nathanael Burwash, George Monro Grant, and William Caven were able to find creative ways to move their churches toward social reform in the late nineteenth century.
The evangelical synthesis lost its cultural supremacy only in the twentieth century, when the complexity of theological discussion in the church colleges broke down the close links between professor and preacher.
