We make a leap now of just a hundred years. From 1689 we pass to 1789, and find ourselves in the city of Philadelphia, at a convention assembled for the purpose of framing a constitution and setting forth a liturgy for a body of Christians destined to be known as the Protestant Episcopal Church in the United States of America. During the interval between the issue of the Declaration of Independence and the Ratification of the Constitution of the United States, the people in this country who had been brought up in the communion of the Church of England found themselves ecclesiastically in a very delicate position indeed. As colonists they had been canonically under the spiritual jurisdiction of the Bishop of London, a somewhat remote diocesan. But with this Episcopal bond broken and no new one formed, they seemed to be in a peculiar sense adrift. It does not fall to me to narrate the steps that led to the final establishment of the episcopacy upon a sure foundation, nor yet to trace the process through which the Church's legislative system came gradually to its completion. Our interest is a liturgical one, and our subject matter the evolution of the Prayer Book. I say nothing, therefore, of other matters that were debated in the Convention of 1789, but shall propose instead that we confine ourselves to what was said and done about the Prayer Book. In order, however, fully to appreciate the situation we must go back a little. In a half-formal and half-informal fashion there had come into existence, four years before this Convention of 1789 assembled, an American Liturgy now known by the name of _The Proposed Book_. It had been compiled on the basis of the English Prayer Book by a Committee of three eminent clergymen, Dr. White of Pennsylvania, Dr. William Smith of Maryland, and Dr. Wharton of Delaware. Precisely what measure of acceptance this book enjoyed, or to what extent it came actually into use, are difficult, perhaps hopeless questions. What we know for certain is that the public opinion of the greater number of Churchmen rejected it as inadequate and unsatisfactory. In the Convention of 1789 The Proposed Book does not seem to have been seriously considered in open debate at all, though doubtless there was much talk about it, much controversy over its merits and demerits at Philadelphia dinner-tables and elsewhere while the session was in progress.
