T HREE INTERRELATED TRENDS have been outlined in the course of this study: the transformation of diverse groups into a public, the shift from religious to secular interests, and the sequence of revivalistic fervor and denominational consolidation. These trends have been considered with respect to the long-term developments of history as well as with regard to their short-term interactions in the particular situation of Colonial Pennsylvania. The pattern of the interaction of these trends has been delineated in detail. The foremost elements of this pattern are the growth of indigenous American church organizations as a contribution to American self-reliance, the role of denominational groups as vehicles of political partisanship, the emancipation of the layman in the time of the Great Awakening as the origin of political self-assertiveness, and the replacement of religious leaders by secular leaders. These developments have been seen as a phase in the alternating current of experience and organization, which pervades the stream of life running from generation to generation. Experience always claims a direct access to reason or revelation, while organization insists on the continuity and stability of institutions. Thus individual experience will always be in conflict with communal organization, and when organization has become stiff and obsolete it will always face the threat of revival and revolt.
