I see. If the Akoimetoi actually became semi-Nestorian, I have no problem admitting it. Eutyches forced Leo to emphasize the two natures without confusion, but Leo also emphasized the one undivided person. There were real Monophysite temptations in the East. So, although some Westerners wrongly opposed condemning the Three Chapters, they were not necessarily semi-Nestorian for doing so. They were suspicious of possible attempts to chip away at Chalcedon to placate Monophysites. The term “Neo-Chalcedonian” is a prejudiced (even slanderous) term based on the false idea that 451 and 553 were inconsistent. 451 admitted bishops who condemned Nestorius. 451 did not deeply investigate all the many writings of Theodore, Diodore, Ibas, and Theodoret. The purpose of 451 was to reject, by consensus, the Eutychian extreme, and confirm a consensus condemning the Nestorian extreme. So, again, those who rejected Nestorius were admitted in 451. By the time of 553, the Church had investigated Origen’s many followers, Theodore and associates, and the “moderate” Severan miaphysites. 553 was very judicious in method and Orthodox in result. It was not a corrective to Chalcedon. Rather, it decided on matters that Chalcedon never intended to investigate deeply, after an additional century allowed such deep investigations. The Holy Spirit guided the Church during the challenges from Arius, Apollinarius, Macedonius, Nestorius, Eutyches, Dioscorus, Severus, and various Origenists. Some Copts apparently honor Origen and Didymus the Blind because they were Egyptian heroes. Orthodoxy rejects them, along with Evagrius of Pontus, at the same time acknowledging that they wrote some very good things, but are not reliable overall. To repeat: Christianity believes in one person Christ with unconfused and undivided Godhood and manhood. The Nestorian distortion tends toward division. The Anti-Chalcedonians all tend toward confusion.
