MONOPHYSITE DOCTRINE
The distinctive doctrine of monophysitism, that from which the name of the heresy is taken, is the assertion that there is but one nature, the divine nature, in Christ. There existed some difference of opinion among the monophysites as to whether any degree of reality might be ascribed to the human nature. Some were prepared to allow it conceptual reality; they would grant that Christ had been diphysite momentarily, that He was "out of two natures." But that admission is quite inadequate. It amounts to no more than the paltry concession that Christ's human nature before the incarnation is conceivable as a separate entity. All monophysites united in condemning the diphysite doctrine that after the incarnation Christ was and is "in two natures." Such a Christ they would not worship. It was "the image with two faces that the Council of Chalcedon had set up."[[1]] They adopted the Athanasian phrase, "One incarnate nature of God the Word," as their battle-cry.
Monophysitism can make out a strong prima facie case. It is attractive at first sight. The heretical formula seems simpler and more natural than the catholic. The unity of nature appears a corollary of the unity of person. Human personality is ordinarily assumed to be monophysite; so it is natural to make the same assumption as to divine personality. The simplicity of the doctrine is, however, all on the surface. It will not bear examination. As a definition of Christian faith it is useless. It cannot account for the recorded facts of Christ's life. The facts of His body, of His mind, of His sufferings refuse to fit into it. It affords no foundation for belief in His transcendent work. No intelligible doctrine of redemption can be built upon it. It contains no germ of hope for mankind. Therefore the Church in the name of Christ and on behalf of humanity rejected it.
Although the heresy has been officially condemned, it should none the less be studied. It is improbable that any one in our time will defend the formula, or openly profess the doctrines that follow from it. But, though not recognised as such, it is an ever-present and instant menace to the Faith. Monophysite tendencies are inherent in religious thought. The metaphysical idea, on which it rests, still has a powerful hold over the human mind. Spiritually-minded men are especially liable to this form of error. It is a mistake to think that Christological questions were settled once and for all in the fifth century. Each generation has to settle them afresh. Accordingly, to exhibit the consequences of the monophysite formula, to show how wrong abstract ideas develop into wrong concrete ideas and falsify Christian practice, is a task of practical and present-day importance.
CLASSIFICATION OF MONOPHYSITE ERRORS
Two classes of erroneous beliefs result from a misconception of the relation between God and man in Christ. There arise, on the one hand, false opinions about the deity of Christ, and on the other, false opinions as to His manhood. We shall adopt this classification as we investigate the doctrinal consequences of the monophysite formula. It is the method followed in one of the earliest systematic criticisms of the heresy. Leo's Tome, or letter to Flavian, contains a lucid statement of the catholic doctrine of the incarnation, and an acute analysis of the system of Eutyches, the heresiarch. He summarises the errors of Eutyches under two heads; there are two main counts in his indictment of the heresy. Eutyches, he contends, makes Jesus Christ "deus passibilis et homo falsus." Eutyches and his followers compromised both deity and humanity. The deity becomes passible, the humanity unreal. All the monophysite misbeliefs can be classified under one or other of these two heads.
THE CONCEPT "IMPASSIBILITY" AS APPLIED TO DEITY
We shall take first those errors that compromise the nature of the deity, and shall preface our analysis by an explanation of the meaning of the term "deus impassibilis." The impassibility of God is the corner-stone of spiritual monotheism. Christianity owes it, as a philosophic doctrine, largely to Aristotle. He conceived deity as "actus purus," as the One who moves without being moved, a "causa sui." The popular gods of Greece were passible; they were possible objects of sense; they were acted on largely as man is acted on. They had a beginning, and were subject to many of the processes of time. They were swayed by human motives. They were, at times, angry, afraid, unsatisfied, ambitious, jealous. Aristotle gave to the world the conception of a transcendent God, a being who is real and yet is "without body, parts and passions," who cannot receive idolatrous worship, and is not an object of sense. Impassibility was one of the highest attributes of this being. The attribute does not involve or imply absence of feeling. Originally it had no reference to feeling, in the psychological sense of that word. It certainly excludes incidentally the lower, specifically human feelings, feelings caused by external stimuli, feelings due to want or to lack of power. It does not exclude the higher affections from the deity. Even in the nóêsis noêseôs of Aristotle, there is room for the transcendent bliss of divine self-contemplation. Much more in the Christian God is there room for spontaneous feeling, springing from His own nature, the necessary concomitant of thought and will. Impassibility is a comprehensive attribute. Originally negative, it soon acquired a rich positive connotation. An impassible God is one who is outside space and time. The attribute connotes creative power, eternity, infinity, permanence. A passible God is corruptible, i.e. susceptible to the processes of becoming, change, and decay. If to-day theists have to be on their guard against debased conceptions of deity, in the plausible garb of an "invisible king," of a finite or suffering God, much more was such caution necessary in the early centuries of the Christian era. Christians who came daily and hourly into contact with polytheistic beliefs and practices had to be very jealous for the concept of impassibility. It represented to them all that was distinctive in the highest region of their Faith.
Monophysitism, as we proceed to show, compromised this article of the Faith. Its adherents did not, perhaps, do so intentionally. In fact, the first generation of monophysites maintained that their definition safeguarded the impassibility. It was zeal for the honour of the Son of God that induced them to deny Him all contact with humanity. Their good intentions, however, could not permanently counteract the evil inherent in their system. In later generations the evil came to the surface. Theopaschitism, the doctrine that openly denies the impassibility of the godhead, flourished in the monophysite churches.
