It is always surprising to see how much a scholar can put together in less than 200 pages (and in this case, 159!). Richard A. Norris, Jr., has canvased the landscape of the early stages of Christological formation and brought this important, accessible, and resourceful primer together: The Christological Controversy. Landmark Church Father figures, such as Irenaeus, Tertullian, Origen, Athanasius, and Cyril, are listed with checkered figures, such as Apollinaris, Theodore, and Nestorius (Origen can be argued to be listed here, as well). And in this way, the tensions are real.
It would be ironic to say that heresies make orthodoxy, but that seems like the case for early Christological controversies. These heresies and the condemned heretics who espoused them were either trying to say too much or too neatly fixed that they suffocate orthodoxy. Most, or all, of the precise wordings of the Great Ecumenical Creeds were hammered during and after heated debates. So, it’s important to keep in mind not only that these great creeds are in a very Hellenistic worldview but also in very complicated, drawn-out debates (via pony express). To say Jesus is “true God from true God” shocks Arius, and “true man from true man” shudders gnostics and docetics.
To be sure, Norris nor even the great Church Fathers were attempting to solve a problem or fix a paradox. Jesus as God-Man is, utterly, mysterious. Yet, in the spirit of Augustine, so that we would not be silenced, we must say something — rightly and worshipfully, within orthodox and orthopraxis.
