Gregory of Nazianzen

Gregory of Nazianzen wrote against Apollinarianism, the belief that Jesus incarnated into man but did not indwell a human mind, saying,

If anyone has put his trust in him as a man without a human mind, he is wholly bereft of mind, and quite unworthy of salvation. For that which he has not assumed he has not healed; but that which is united to his Godhead is also saved
