Since there seems to be widespread misunderstanding regarding the heresy of Nestorianism and what Nestorius actually taught, I’ve decided to post some notes illustrating and explicating Nestorius’ teaching. I have used McGuckin’s, Saint Cyril of Alexandria and the Christological Controversy. I’ve numbered selections for ease of reference. There are a number of things to notice in the notes. Notice the problem of mixture. This was a significant issue all by itself in antiquity since for Platonists as well as Aristotle, matter was not intrinsically extensional as the modern conception has it. A mixture was a meeting of powers. Notice also that Nestorius takes the will to be almost exclusively hypostatic rather than natural so that there is only one will in “Christ.” Terms like “Christ” also do not refer to the eternal Logos exclusively but the end result of the union. There is also an apparent confusion between person and nature as manifested in Nestorius’ language concerning the eternal hypostasis of the Logos,where hypostasis seems to do double duty to refer to the divine essence as well as the divine person. A person then seems to be an instance of a kind. It is entirely unclear where or what the divine person of the Logos is. Also notice the extrinsic relation he posits between the two instantated essences or “hypostases” where one uses the other in an instrumental way such that the union transcends nature and is one of “grace.” Christ was then the chief moral examplar. It isn’t hard to see why the Pelagians cuddled up to the Nestorians. On the other end, the instruemtnalization of Christ’s humanity with the union as one of “grace” as superior to nature maps onto Augustine’s Christology. Some overlap into semiotics is also important as well as the preceding history of medical science in the notion of prosopon as a “sign” of a nature or a somewhat metaphysically thined out energy.
1. “To be fully human, on the other hand, demands that one must be ready to attribute to Christ the fully panoply of human characteristics, excepting sin which is not a ‘humanising’ characteristic or even a defining human attribute in any case. He must have a human mind, a human soul with human feelings choices and limitations, both mental and physical, involving him in a range of testing situations (the temptations of the Lord) which proved and refined his virtue as a man, and which involved him inexorably in all the suffering consequent on being human. Nestorius was unswerving on the point that this demanded that the approach of Apollinaris represented a dead-end…here it will suffice to remark that Apollinaris had found no place for a human limited consciousness in Christ, or for a human soul which could be considered as the seat of genuine human choices. Apollinaris’ logic demanded that these things must be sacrificed in the interests of the unity of the person of Christ, if one were to accept the infinite mind of the Logos inhabited his human frame. Nestorius took the earlier Christological heresy of Docetism as an extreme form of the same tendency in Apollinaris to acknowledge merely the appearance of fleshly limitations in the divine Christ who was really unlimited.
For Nestorius it was this tendency to absorb or evaporate away the human reality in the face of the divine that was the chief deficiency of Apollinaris’ heresy, and like Gregory Nazienzen before him he attacked such presuppositions on soteirological grounds, for a theory of incarnation that wiped away the human reality in the advent of the deity constituted not only a failure of revelation theology but an inability to value the extraordinary role which the Christian Gospel gave to human experience in its conception of God’s redeeming work. Nestorius taught that such ‘absorption theory’ in Christology was sub-christian or mythological, inevitably involving its proponents in concepts of incarnation based upon Krasis or mixture. He was ever on the look out for the ‘mixture’ or ‘confusion’ of divine and human spheres of reality in Christological discourse, and regarded this as the most serious deficiency of Cyril’s work. He regarded all sense of ‘mixture’ as inevitably connoting change, and even the annihilation, of the individual elements that were so mixed.”
