Contemporary references to these matters as they presented themselves to the attention of those who here first entered into a “church estate,” are scattered over Governor Winthrop’s journal. John Cotton, minister of the First Church of Boston, diligently and earnestly, in successive writings and publications, set himself to answering all questioning and challenging friends abroad. He evidently had to work out clear and consistent views of his own on a subject which, besides being novel in many of its relations, was embarrassed by local difficulties, and by some conscientious or practical diversities of judgment among his associates. Richard Mather, of Dorchester, also contributed his help in the exposition of the Congregational polity, which was to be defended alike from extreme Barrowism and from Presbyterianism, which was soon found to have some sympathizers in the colony. By a sort of general consent, recourse was had to a succession of “synods,” or councils of the representatives of the churches, first those of the Bay Colony alone, then with some of the other New England colonies. These synods resulted in the formation of a “Platform,” which laid out in form and detail the system of the Congregational polity. It is not necessary here to indicate the titles, contents, and authors of the several publications, preserved in our cabinets of relics, which contributed either to the dissension or to the pacification of the sometimes eccentric and heated, and of the always scrupulous, earnest, and independent parties in this work of ecclesiastical reconstruction. They have been so faithfully, admirably, and impartially digested by Dr. Dexter in the eighth of the lectures in his _Congregationalism_, as to present to the reader a full and intelligent view of the whole subject in its development and its results, while relieving him of what save to the fewest possible of historical students would be a repelling task. If, however, zeal or curiosity should dispose any one to peer through those dried and withered relics of the old polemics of a generation that drew its honey from the rocks, he will find much occasion to respect the acuteness and the persistency of men who, having taken the interests of their creed and piety into their own hands, determined to build on what was to them the only sure foundation. That foundation was “the Word.” If the Scriptures, as their prelatical foes insisted, were not intended to afford, and would not afford, a complete pattern of a method of institution and government of a Christian Church, the reader of those patiently wrought tractates will often be amazed as he notes how rich and fertile, how apt and facile, the contents of the sacred books were found to be, in furnishing the requisite material for argument and authority.
