Abstract
This paper discusses the theology of Alexander Penrose Forbes, Bishop of Brechin in the Scottish Episcopal Church and the first Anglican bishop in the British Isles to be deeply influenced by Tractarianism. A close confidant of Edward Bouverie Pusey, he extended Pusey's patristic proof-texting method into discussion of the Church of England formularies, especially the Thirty-nine Articles of Religion. His main work was an explanation of this key reformation text, which offers a good illustration of a historicist understanding of Catholicism. Like Pusey, Forbes was involved in ecumenical discussion with Roman Catholics, and was motivated principally by the attempt to find a common conservative front against the perceived liberalism that seemed to be affecting European religion and politics in the mid-nineteenth century.
