Presented in this way the monophysite and other Christological controversies of the fifth and sixth centuries become phases of the cosmic problem. They thus regain the dignity which is theirs by right, and which they lose in the ordinary church histories. The heat of passion they aroused becomes intelligible. It was no battle about words. The stakes were high. The controversialists championed far-reaching principles with a decisive influence on the course of thought and conduct. Unfriendly critics usually portray the Christologians as narrow-minded and audacious. So, no doubt, they were, but they were not wrong-headed. If the matters in dispute between theist, deist, and pantheist are trivialities, then and then only can we regard the enterprise of the Christologians as chimerical and their achievements as futile. The different formulae represented attitudes of mind fundamentally opposed. No peace between catholic and monophysite was possible. They had conflicting conceptions of ultimate truth.
DEPENDENCE OF CHRISTOLOGY ON PHILOSOPHY
We mentioned above the two other chief Christological systems, the Nestorian and the catholic. No analysis of monophysitism which omitted a reference to these systems would be complete. They were three nearly contemporary attempts to solve the same problem. The comparison is of special interest when, as here, fundamental principles are under examination. It demonstrates the closeness of the connection between the Christological and the cosmic problems. In each of the three cases we find that a school of philosophy corresponds to the school of theology, and that the philosopher's dominant idea about the cosmos decided the theologian's interpretation of Christ.
This connection between philosophy and Christology is of early date. From the nature of both disciplines it had to be. Even in apostolic days the meaning of the incarnation was realised. Christ was apprehended as a being of more than national or terrestrial importance. The Pauline and Johannine Christologies gave cosmic significance to His work, and so inevitably to His Person. Theologians made the tremendous surmise that Jesus of Nazareth was no other than the Logos of the Neo-Pythagoreans or the Wise One of the Stoics. That is to say, He stands not only between God and man, but between Creator and creation. He is the embodiment of the cosmic relation. From early days, then, philosophy and religion were working at the same problem; their paths met at the one goal of the Ideal Person who satisfied both head and heart. The systematic Christology of the fifth century was, therefore, a completion of the work begun in the first.
THE CHRISTOLOGICAL AND THE COSMIC PROBLEMS
The essence of the Christological problem is the question as to the union of natures in Christ. Are there two natures divine and human in Him? Is each distinct from the other and from the person? Is the distinction conceptual or actual? The incarnation is a union. Is it a real union? If so, what did it unite? We have seen that such questions cannot be approached without presuppositions. What these presuppositions shall be is decided in the sphere of a wider problem. This wider problem is known as the cosmic problem. The solution given to it prescribes the presuppositions of any attempt to solve the specialised problem. We shall proceed to sketch the cosmic problem, and to indicate the three main types of answers given to it. It will then be evident that these three answers find their respective counterparts in the Nestorian, monophysite and the catholic solutions of the Christological problem.
As man's intellectual powers mature, two supreme generalisations force themselves on his consciousness. He conceives his experience as a whole and calls it the world; he conceives the basis of his experience as a whole and calls it God. To some minds the world, to some minds God, is the greater reality; but both concepts are present in varying proportions wherever thought becomes self-conscious. Here we have in its lowest terms the material for the ontological question, the first and the last problem of philosophy. God and the world, at first dimly conceived and scarcely differentiated, gradually separate and take shape in the mind as distinct entities. The concepts become principles, fixed by language and mental imagery. The gulf between them widens until they stand at opposite poles of thought. In their isolation they constitute a standing challenge to the mind of man. If he thinks the world in terms of time, he must postulate a creator. If he thinks the world out of time, he is forced to conceive a ground of the world's being. The world cannot be thought without God nor God without the world. The one necessitates the other. Yet when the thinker tries to define the terms, he can at first only do so by negatives. The world is what God is not, and God is what the world is not. The two primary concepts thus attract and repel each other. The mind's first task is to grasp them in their difference. It cannot rest there, but must proceed to attempt to reunite them and grasp them in their unity. Thus the main problem of philosophy is to conceive and find expression for the relation between God and the world. Christology attacks essentially the same problem. Christology is an attempt to define the relation between God and the world in terms of personality.
This relation has been conceived in three modes. According to the level of thought reached, or, as led by their disposition and education, men have made their choice between three mediating concepts. Hence derive three divergent types of thought and three outlooks on life fundamentally opposed. We shall take them in their logical sequence for convenience of treatment. The historical connection is of no importance for our present purpose, but it is noteworthy that the time order both of the schools of philosophy and of the corresponding Christological systems follows approximately the logical order.
THE FIRST SOLUTION OF THE COSMIC PROBLEM—DUALISM
The first attempted solution of the cosmic problem is best expressed in the concept "co-existence." God and the world co-exist. God is, and the world is; their relation is expressed by an "and." "God and the world" is the truth, all that man can and need know. This solution is verbal. It leaves the problem more or less as it finds it. The two principles remain ultimates; neither is reduced to the other. God still stands outside the world and the world outside God. Neither can explain the other. This dualism is the lowest stage of ontological thought. The thinker sees the problem, only to turn away from it. He surmises that there is some relation between the two; but he cannot define it, and it remains ineffectual. This was Plato's early standpoint. He established the idea as the truth of the thing, but he failed to find expression for the relation between idea and ideate. He took refuge in symbolical language, and spoke of the thing as a "copy" of the idea or as a "participant" in it. But as there was no causation on the one side or dependence on the other side, all that the earlier Platonic philosophy achieved was in its ideal world to duplicate the real. Plato's heaven simply co-exists with the world, and the relation between them is merely verbal.
