S.J. Robert M. Doran 
Trinity in History: A Theology of the Divine Missions [PDF ebook] 
Volume Two: Missions, Relations, and Persons

The second volume of Robert M. Doran’s magisterial The Trinity in History continues his exploration of the Trinitarian theology of Bernard Lonergan, focusing now on the notions of relations and persons and connecting the systematic proposals with the so-called "Third Quest for the Historical Jesus." Doran not only interprets Lonergan’s major work in Trinitarian theology and Christology but also suggests at least a twofold advance: a new version of the psychological analogy for understanding Trinitarian doctrine and a new starting point for the whole of systematic theology. He links these theological concerns with Rene Girard’s mimetic theory, proposes a theory of history based in Lonergan’s scale of values, and creates a link between exegetical and historical scholarship and systematic theology.
