A Dissertation submitted to the Faculty of the Graduate School, Marquette University, in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy Milwaukee, Wisconsin May 2011 ABSTRACT THE TRINITARIAN THEOLOGY OF IRENAEUS OF LYONS Jackson Lashier, B.A., M.Div. Marquette University, 2011 This dissertation is a study of the Trinitarian theology of Irenaeus of Lyons. With the exception of two recent studies, Irenaeus’ Trinitarian theology, particularly in its immanent manifestation, has been devalued by scholarship due to his early dates and his stated purpose of avoiding speculative theology. In contrast to this majority opinion, I argue that Irenaeus’ works show a mature understanding of the Trinity, in both its immanent and economic manifestations, which is occasioned by Valentinianism. Moreover, his Trinitarian theology represents a significant advancement upon that of his sources, the so-called apologists, whose understanding of the divine nature converges in many respects with Valentinian theology. I display this advancement by comparing the thought of Irenaeus with that of Justin, Athenagoras, and Theophilus, on Trinitarian themes. Irenaeus develops Trinitarian theology in the following ways. First, he defines God’s nature as spirit, thus maintaining the divine transcendence through God’s higher order of being as opposed to the use of spatial imagery (God is separated/far away from creation).
