value as such. They are not all on the same level of being; they do not occupy the same rank; and it is the philosopher's business to determine their respective positions in the scale of being and value. But he cannot have his head in the clouds of contemplation, unless he have his feet on the earth of fact.

THE ESSENCE OF CATHOLIC CHRISTOLOGY

Catholic Christology has caught the spirit of Aristotle's teaching. It is not primarily speculative. It is in close touch with fact. It is the outcome of a deep-felt want. Redemption is the first demand of religious experience; so it is the motive and theme of all Christology. The soul views itself as a member of a world of souls estranged from God, and for its own peace and welfare seeks to effect a union between God and the world. Such a union, to be effective, must preserve the being and value of the world. If there were no world or only a valueless world, there would be nothing to redeem, or nothing worth redeeming. Seeking that union in personality, and in the most marvellous personality of history, the orthodox theologians by a true instinct ascribed to Him both divine and human natures. He is the cosmic unity of opposites. His person is the cosmic relation. In that person the lower term of the relation has true being and full value. Thus the Church steered a middle course between the Scylla of co-existence and the Charybdis of identity.

These a priori deductions as to the being of Christ were verified by a reference to fact. The life-story of the historic Christ comprises two distinct groups of experience. There are thoughts, deeds, and words attributed to Him that only God could have thought, done, and said. There are as well thoughts, deeds and words of His that only a man could have thought, done and said. Hence the diphysite doctrine was verified a posteriori. Again, in both groups of experience there is a never-failing connecting link. There is a unity lying deeper in His consciousness than the duality. Christ, the Agent, is the same in both parts. Whether as God or man, He is never out of character. Hence the unity of the person also was established a posteriori. Thus, to the orthodox Christologians, the expectation that the human Ideal would be a unity, comprising divinity and humanity, was justified by historical fact.

They found a further verification on applying the test of practice. Orthodox Christology satisfies the requirements of the soul. Man's chief spiritual need is access to God through "a daysman that might lay his hand upon both." An exemplar, even though perfect, is not adequate to his need. The unio mystica can only be experienced by the leisured few. Man demands a religion of redemption, a redemption that allows value to labour, to endeavour, to human thought, that recognises the reality of pain and sorrow and sin, a redemption that redeems humanity in all its phases and in the wealth of its experiences. An Agent that has not shared to the full those experiences is useless for the purpose. Redemption must be the work of One who knows God and knows man, of One who has the touch of sympathy; for to such a touch alone can humanity respond. The Christology that makes Christ Jesus consubstantial with God and with man satisfies man's deep-felt need.

SUMMARY OF THE CHAPTER

We have taken a triad of ontologies and a triad of Christological systems, placed them side by side, and examined them. The result of that examination is a triple correspondence. The metaphysical principle is found in each case worked out in a corresponding Christology. The comparison is of general interest. It reveals Christology as intimately connected with the workings of intellect, as in the main stream of the current of human thought, as capable of philosophic treatment. Further than that, the comparison is vital to the main argument of this essay. It provides the clue to the heart of our subject. The scientist, who wishes to understand a botanical specimen, pays as much attention to what is in the ground as to what is above ground. The seed and roots are as full of scientific interest as are stem, leaf and flower. Similarly, to understand the monophysite heresy, to be able to detect it and expose it, we must take it in the germ. We may push the illustration further. The properties of a botanical specimen are best studied in connection with organisms of allied species. We cannot isolate unless we compare. By comparison the essential features, functions and properties of the specimen under examination are elucidated.

It is by isolating the three germinal ideas of these three Christological systems and comparing them, that a full comprehension of monophysitism in all its stages, from seed to flower, is reached. We have used this method, and have found that the roots of the heresy lie in spiritual monism. In subsequent chapters we shall analyse its origins as a historical system, its specific tenets and its practical consequences. It will then be seen that the spirit of monism pervades the whole system.

CHAPTER II

THE ORIGINS OF MONOPHYSITISM

The monophysitism of the fifth century had its roots in the past as well as in the a priori. In the previous chapter we treated it as a phase of philosophic thought and reviewed the metaphysic on which the heresy rests. In the present chapter its relations as a historical system of religious thought are to be exhibited. As such, it owes much to outside influences. Much in the monophysite mode of thought and many of its specific doctrines can be traced either to other ecclesiastical heresies or to pagan philosophies. The fact of this double derivation deserves to be emphasised. It refutes the charge of inquisitorial bigotry, so frequently levelled against the theologians of the early centuries. The non-Christian affinities of the heresy account for the bitterness of the controversy to which it gave rise, and, in large measure, excuse the intolerance shown by both parties. Heresies were not domestic quarrels. Contemporaries viewed them as involving a life and death struggle between believers and unbelievers. Christianity can afford to be tolerant to-day. It has an assured position. Its tenets are defined. Christians can almost always distinguish at a glance errors that threaten the essentials of the Faith from those that do not. In the fourth and fifth centuries the case was otherwise. Christianity was then one among many conflicting systems of religion. Its intellectual bases were as yet only imperfectly thought out. Any doctrinal error seemed capable of poisoning the whole body of belief. Heresy, so the orthodox held, was of the devil. No charitable view of it was allowable. That uncompromising attitude was, to a large extent, justified because many articles of the heretical creeds were of purely pagan origin. Given similar conditions to-day, our easy tolerance of opinion would disappear. If Islam, for instance, were to-day a serious menace to the Faith, Christians would automatically stiffen their attitude towards monophysite doctrines. Toleration of the false Christology would, under those circumstances, be treason to the true. The Church of the fifth century was menaced from many sides. Monophysitism was the foe at her gates. That heresy was not a variety of Christianity. It was a semi-pagan theosophy, a product of Greek and oriental, as well as of purely Christian speculation; therefore it was anathema to the orthodox.

THE ELEMENTAL FORMS OF CHRISTOLOGICAL ERROR—DOCETISM AND EBIONITISM

We propose to begin the study of the antecedents of monophysitism by examining those of a Christian or semi-Christian character. For that purpose it will be necessary to give a brief sketch of the early heresies in so far as they bear on the Christological problem.

The two primitive forms of doctrinal
