Newman's Forensic Classic of Development: Its Uniqueness and Its Agon with Gibbon and Surrogates

In this article I argue for the uniqueness of The Development of Doctrine vis‐à‐vis other classic texts on doctrinal development supplied by the German theologians J.S. Drey and J.A. Möhler. Whereas the accounts of the German theologians are ‘theological’ in the strict sense, Newman's is theological only indirectly and forensic in its primary construction and execution. By ‘forensic’ I mean that the bulk of his reasoning is argumentative and intends to clear a space for thinking plausibly of the development of doctrine given other assumptions in the secular imaginary. While I make plain that in his classic text Newman is taking issue with the barriers against the idea of development from a number of religious constituencies, I suggest that in the end the enemy of enemies are religious rationalists, especially those with a historical sense largely derived from reading Edward Gibbon. Although The Development of Doctrine is an extraordinary text in so many ways, it comes to life when one understands it as Newman doing battle with Gibbon over the proper historiography of Christianity over the ages.
