Samuel Seabury 1729ampndash96 and Charles Inglis 1734ampndash1816 were the first bishops of the Anglican churches in the United States and Canada respectively. This study compares and contrasts the seminal episcopal ministries of both men. Areas investigated include the introduction of episcopal ministry into virgin territory respecting such matters as confirmation ordination and clerical discipline. Unlike Inglis Seabury was forced to deal with wholesale liturgical revision. Seabury rejected the ampquotProposed Prayer Book of 1785ampquot and the revision of 1789. While both editions were generally accepted for the sake of denominational unity they were far from Seaburyamp39s ideal. As liturgical revision was intertwined with polity ecclesiology is considered in detail in the concluding chapter. Through a consideration of the early Lambeth Conferences the conclusion draws out the implications for the Anglican Communion of these two seminal episcopacies. It is argued that the polity and liturgy of each national church established in Seaburyamp39s and Inglisamp39 era has had implications reaching far beyond their own times.
