[3] Theodoret charged Apollinaris with confounding the persons of the Godhead and giving in to the heretical ways of Sabellius.
Apollinaris, considering the rational soul and spirit as essentially liable to sin and capable, at its best, of only precarious efforts, saw no way of saving Christ's impeccability and the infinite value of Redemption, except by the elimination of the human spirit from Jesus' humanity, and the substitution of the Divine Logos in its stead.
[2] Christian philosopher William Lane Craig has proposed a neo-Apollinarian Christology in which the divine Logos completes the human nature of Christ.
Craig also clarifies "what I called a Neo-Apollinarian Christological model" by stating that What I argue in my Neo-Apollinarian proposal is that the Logos brought to the human body just those properties which would make it a complete human nature – things like rationality, self-consciousness, freedom of the will, and so forth.
Christ already possessed those in his divine nature, and it is in virtue of those that we are created in the image of God.
