It may be doubted whether to any man of his generation it was given to exercise a wider and more beneficent influence over the American church than that of President Dwight. His system of "Theology Explained and Defended in a Series of Sermons," a theology meant to be preached and made effective in convincing men and converting them to the service of God, was so constructed as to be completed within the four years of the college curriculum, so that every graduate should have heard the whole of it. The influence of it has not been limited by the boundaries of our country, nor has it expired with the century just completed since President Dwight's accession. At the East also, as well as at the West, the quickening of religious thought and feeling had the common effect of alienating and disrupting. Diverging tendencies, which had begun to disclose themselves in the discussions between Edwards and Chauncy in their respective volumes of "Thoughts" on the Great Awakening, became emphasized in the revival of 1800. That liberalism which had begun as a protest against a too peremptory style of dogmatism was rapidly advancing toward a dogmatic denial of points deemed by the opposite party to be essential. Dogmatic differences were aggravated by differences of taste and temperament, and everything was working toward the schism by which some sincere and zealous souls should seek to do God service. In one most important particular the revival of 1800 was happily distinguished from the Great Awakening of 1740. It was not done and over with at the end of a few years, and then followed by a long period of reaction. It was the beginning of a long period of vigorous and "abundant life," moving forward, not, indeed, with even and unvarying flow, yet with continuous current, marked with those alternations of exaltation and subsidence which seem, whether for evil or for good, to have become a fixed characteristic of American church history.
