According to Alexandrian Christology, God must be one with human nature, so human’s can share a life with God. (McGrath 46). Therefore, God became human to be able to relate to humanity. Apollinaris of Laodicea had a different view; he believed “Christ’s human mind and soul were replaced with a divine, pure mind” (McGrath 47). His argument against Alexandrian Christology was that Jesus’ actions would not be Christ with a human mind. If Christ were human, he would possess a dirty, weak mind and be vulnerable to sinning.
Gregory of Nazianzus challenged Apollinaris’ idea with the question: “How could human nature be redeemed, if only part of human nature had been assumed by Logos?”
