One might write a history of dogma as a history of the Pauline reactions in the church, and in doing so would touch on all the turning points of the history. Marcion after the Apostolic Fathers; Irenaeus, Clement and Origen after the Apologists; Augustine after the Fathers of the Greek Church; the great Reformers of the Middle Ages from Agobard to Wessel in the bosom of the medieval Church; Luther after the Scholastics; Jansenism after the Council of Trent; everywhere it has been Paul, in these men, who produced the Reformation. Paulinism has proved to be a ferment in the history of dogma, a basis it has never been.
