But as piously as Holy Scripture has spoken, the holy Church has thought it ought to speak just as cautiously, so that, namely, it might embrace both one person and two distinct natures, by which manner it might avoid Nestorian distraction and Eutychian confusion of natures, as if avoiding two rocky reefs. Nestorius, because he did not consider the distinction between concrete and abstract, and did not concede that God suffered in his humanity, thus fell into the splitting of the person. Eutyches, on the contrary, lest he separate the natures, impiously imagined that the human was converted into the deity.

Justin in the Exposition of Faith: Therefore, there is one Son, who both loosened and restored that which had been loosened; for in that He is man, He loosened, but in that He is God, He restored. Therefore, when you hear voices that are diverse from one another concerning one Son, distribute them according to the natures compared with one another: if anything great and divine, ascribing it to the divine nature; but if small and human, imputing it to the human. For by this pact, you will avoid the dissonance of voices, since each nature receives that which is innate to it; and you will profess one Son both before the ages and recently brought forth, according to the sentiment of the sacred scriptures.
