When we compare monophysitism with the system of Plotinus, several points of resemblance appear. There is first the impersonal character of the deity. Monophysitism was not a Trinitarian heresy, and the Catholic doctrine of the three persons in the godhead was the official creed of the heretical church. But their theologians refrained from laying emphasis upon the distinct personalities of Father, Son and Holy Ghost. Their sympathies were Sabellian to the core, and Sabellian heresies were constantly recurring within their communion. The impersonal Trinity, such as Plotinus taught, was thoroughly in keeping with their Christology. They lacked a clear conception of personality in the second Person of the Trinity. It was inevitable that they should overlook the same element in the incarnate Christ. The Neo-Platonic view of matter finds its counterpart in monophysite theory. The monophysites, without formally denying its real existence, nursed a Manichean suspicion of it. It was, to them, the seat of illusion; it was an obstacle to spirit, the enemy of spiritual development. If not unreal, it was at any rate unworthy. The association of Christ with matter through His body and through His human nature was, in their eyes, a degradation of deity. That Christ took matter up into His being as a permanent element, that He dignified the body and glorified human faculties, these facts seemed to the monophysite mind improbable, and, if true, devoid of religious significance. It came natural to him to explain Christ's body as a phantom. He was prepared to regard the human nature as unsubstantial. The mystic's view of matter, of sense and human existence characterises the whole monophysite outlook.
