of two co-ordinate entities. They taught that the more the man Jesus acted in accordance with the divine promptings, the closer became his union with the Logos. That is to say, the union was relative not absolute. Thus the union between divine and human in Christ differed only in degree from the union of the same elements in any good man. The unity of the Son of God and the Son of Mary consisted solely in the identity of name, honour and worship.

CYRIL OF ALEXANDRIA

Cyril, Bishop of Alexandria, led the opposition to Nestorius. He declared that the moment of conception was the moment of the union, and that the notion of incarnation involved much more than an association of natures. He maintained that the incarnation was a hypostatic union (hénôsis physiké). He endeavoured to guard against an Apollinarian interpretation of his teaching; but in this attempt he was not altogether successful. He asserted the perfection of Christ's humanity and the distinction between the two natures. The perfection, however, is compromised, and the distinction rendered purely ideal by his further statement that there were "two natures before, but only one after the union." He cited in proof the words of Athanasius, "one incarnate nature of God the Word."

Cyril prevailed. Nestorius was condemned and the Antiochian school discredited. Cyril's victory, however, was of doubtful value to orthodoxy. His ardent but unbalanced utterances bequeathed to the Church a legacy of strife. His writings, particularly the earlier ones, furnished the monophysites with an armoury of weapons. His teaching could not with justice be styled docetic or Apollinarian, but its mystic tone was so pronounced that it proved a propaedeutic for monophysitism. The shibboleth of orthodoxy, quoted above, "one incarnate nature of God the Word," passed rapidly into the watchword of heresy. Athanasius had used the word "nature" in a broad sense. The monophysites narrowed it down to its later technical meaning. Thus they exalted Christ into a region beyond the ken of mortal man. The incarnation became a mystery pure and simple, unintelligible, calling for blind acceptance. The monophysites, following Cyril, heightened the mystery, but, in doing so, they eliminated the reality and the human appeal of the incarnate life. They soon began to argue that, since Christ is monophysite, the properties of deity and humanity in Him are interchangeable; that therefore, while yet a Babe in the manger, He ruled the world with the omniscience and omnipresence of the Logos; that while He hanged upon the Cross, His mighty power sustained and ordered the universe. The monophysites professed great jealousy for the honour due to the Redeemer. But the ascription of such attributes to Jesus Christ detracts from His honour. If the nature that suffered on the Cross be not distinct from the nature that cannot suffer, then the Crucifixion was a sham. Monophysitism is docetism elaborated. It abandons the Christ of history. It rules out His prokopé. It ignores a fact, vital to Christology, namely the kénôsis or divine self-limitation. Thus it throws a veil of unreality over those facts on which the Christian Faith is built.

MONOPHYSITISM A PRODUCT OF POSITIVE AND NEGATIVE
CURRENTS OF RELIGIOUS THOUGHT

The foregoing sketch of the early Christological heresies exhibits monophysitism as a product of two opposite intellectual currents. A man's convictions are settled for him partly by acceptance, partly by rejection of what tradition offers or his mind evolves. The mass mind works similarly. It accepts and rejects, approves and disallows. The stabilisation of a body of mass opinions, such as a heresy, is thus determined by opposite forces. It was so with monophysitism. Its Christian antecedents comprised positive and negative currents. The positive current was docetism, the negative ebionitism. Docetism, originating in apostolic times, passed through many phases, to provide, at the end of the fourth century, in its most refined form, Apollinarianism, the immediate positive cause of monophysitism. Ebionitism, related to docetism as realism to idealism, possessed equal vitality and equal adaptability. It showed itself in various humanistic interpretations of Christ. Of these the most elaborate was Nestorianism, which exerted the most insistent and immediate negative influence on the early growth of monophysitism.

MONOPHYSITISM AND NON-CHRISTIAN THOUGHT

We leave here the subject of the influence of other heresies on monophysitism, and proceed to exhibit its affinities with non-Christian thought. At Alexandria, the home of the heresy, two systems of philosophy, the Aristotelian and the Neo-Platonist, were strongly represented. Both of these philosophies exercised a profound influence upon the origins and upon the later developments of monophysite doctrine. We propose to take, first, the Aristotelian, and then the Neo-Platonist philosophy, elucidating those leading ideas in each on which the monophysite thinker would naturally fasten, as lending intellectual support to his religious views.

THE ARISTOTELIAN LOGIC

Aristotle was held in high estimation by the monophysite leaders, particularly in the sixth and seventh centuries. His works were translated into Syriac in the Jacobite schools. The West owes much to these translations. For it was largely by this agency that his metaphysic reached the Arabs, who transmitted it to the West in the Middle Ages.

The Aristotelian logic was widely known among the monophysites. It seems to have formed part of their educational curriculum. Taken apart from the rest of the system, the logic produces a type of mind that revels in subtle argumentation. It exalts the form of thought at the expense of the matter. It had this effect on the monophysite theologians. They were trained dialecticians. They were noted for their controversial powers, for their constant appeal to definition, for the mechanical precision of their arguments. These mental qualities, excellent in themselves, do not conduce to sound theology. Formal logic effects clarity of thought often at the expense of depth. It treats thoughts as things. Procedure, that is proper in the sphere of logic, is out of place in psychology and theology. Concepts such as person and nature must be kept fluid, if they are not to mislead. If they are made into hard and fast ideas, into sharply defined abstractions, they will be taken to represent discrete psychic entities, external to one another as numbers are. The elusive, Protean character of the inter-penetrating realities behind them will be lost to view. The most signal defect of monophysite method is its unquestioning submission to the Aristotelian law of contradiction. The intellectual training that makes men acute logicians disqualifies them for dealing with the living subject. The monophysite Christologians were subtle dialecticians, but the psychology of Christ's being lay outside their competence.

ARISTOTLE'S CRITICISM OF DUALISM—A WEAPON
IN THE HANDS OF THE MONOPHYSITES

Leaving the formal element in Aristotle's system, we come to its material content. Some of the prominent ideas of the Aristotelian cosmology and psychology reappear in the heresy we are studying. We shall take first the rejection of the Platonic dualism. Aristotle's repeated criticism of his master's theory of ideas is not merely destructive. It formed the starting-point for his own metaphysic. The ideas, he says, simply duplicate the world of existent things. They do not create things or move them; they do not explain genesis or process; they merely co-exist with the ideates. The participation which Plato's later theory postulated is inadequate. A more intimate relation is required. The theory of ideas confronts God with a world, and leaves the relation
