St. Ambrose here argues against Apollinarianism, who separated the two natures in Christ and taught that He should not be adored except in His Godhead, giving to the orthodox the nickname of ἀνθρωπολάτραι. The Apollinarians held that Christ was Θεὸς σαρκοφόρος, as Nestorians made Him ἄνθρωπος Θεοφόρος, instead of the proper Θεάνθρωπος. Apollinaris said Christ is οὔτε ἄνθρωπος ἅπλος, οὔτε Θεὸς, ἀλλὰ Θεοῦ καὶ ἀνθρώπου μίξις. He denied the complete human nature of our Lord, saying that the Logos supplied the place of the anima rationalis. This stunted humanity could not be accepted by the Church, as it would involve a merely partial redemption. Christ must be a perfect man, in order to be a perfect Redeemer. The heresy was opposed by St. Athanasius, St. Basil, and others, condemned in synods at Alexandria 362, Rome 373 and probably 382, Antioch 378 or 379, and decisively at Constantinople in the second œcumenical council.
