Here only, in the innermost sanctuary of being, the soul’s “last habitation,” as St. Teresa said, is the truth which these symbols express truly known: for “as to how the Trinity is one and the Trinity in the Unity of the nature is one, whilst nevertheless the Trinity comes forth from the Unity, this cannot be expressed in words,” says Suso, “owing to the simplicity of that deep abyss. Hither it is, into this intelligible where that the spirit, spiritualizing itself, soars up; now flying in the measureless heights, now swimming in the soundless deeps, of the sublime marvels of the Godhead!”238
Mystical philosophy, then, has availed itself gladly of the doctrine of the Trinity in expressing its vision of the nature of that Absolute which is found, by those who attain the deep Abyss of the Godhead, to be essentially One. But it is by the complementary Christian dogma of the Incarnation that it has best been able to describe and explain the nature of the inward and personal mystic experience. The Incarnation, which is for traditional Christianity synonymous with the historical birth and earthly life of Christ, is for mystics of a certain type, not only this but also a perpetual Cosmic and personal process. It is an everlasting bringing forth, in the universe and also in the individual ascending soul, of the divine and perfect Life, the pure character of God, of which the one historical life dramatized the essential constituents. Hence the soul, like the physical embryo, resumes in its upward progress the spiritual life-history of the race. “The one secret, the greatest of all,” says Patmore, is “the doctrine of the Incarnation, regarded not as an historical event which occurred two thousand years ago, but as an event which is renewed in the body of every one who is in the way to the fulfilment of his original destiny.”239
We have seen that for mystical theology the Second Person of the Trinity is the Wisdom of the Father, the Word of Life. The fullness of this Word could therefore only be communicated to the human consciousness by a Life. In the Incarnation this Logos, this divine character of Reality, penetrated the illusions of the sensual world — in other words, the illusions of all the selves whose ideas compose that world — and “saved” it by this infusion of truth. A divine, suffering, self-sacrificing Personality was then shown as the sacred heart of a living, striving universe: and for once the Absolute was exhibited in the terms of finite human existence. Some such event as this breaking through of the divine and archetypal life into the temporal world is perceived by the mystical philosopher to be a necessity, if man was ever to see in terms of life that greatness of life to which he belongs: learn to transcend the world of sense, and rebuild his life upon the levels of reality. “For Thou art,” says Nicolas of Cusa, “the Word of God humanified, and Thou art man deified.”240 Thus it is that the Catholic priest in the Christmas Mass gives thanks, not for the setting in hand of any commercial process of redemption, but for a revelation of reality, “Quia per incarnati Verbi mysterium nova mentis nostrae oculis lux tuae claritatis infulsit: ut dum visibiliter Deum cognoscimus, per hunc in invisibilium amorem rapiamur.” The essence of mystical Christianity seems to be summed up in these lovely words.241
“The Son of God, the Eternal Word in the Father, who is the glance, or brightness, and the power of the light eternity” says Boehme, “must become man and be born in you, if you will know God: otherwise you are in the dark stable and go about groping.”242 “The Word,” says Ruysbroeck finely, “is no other than See. And this is the coming forth and the birth of the Son of the Eternal Light, in Whom all blessedness is seen and known.”243 Once at any rate, they say in effect, the measure of that which it was possible for the Spirit of Life to do and for living creatures to be, was filled to the brim. By this event, all were assured that the ladder of Creation was made whole; in this hypostatic union, the breach between appearance and reality, between God and man, was healed. The Bridge so made — to use St. Catherine of Siena’s allegory again — is eternal, since it was “laid before the foundation of the world” in the “Eternal Now.” Thus the voice of the Father says to her in that vision, “I also wish thee to look at the Bridge of My only-begotten Son, and see the greatness thereof, for it reaches from Heaven to earth; that is, that the earth of your humanity is joined to the greatness of the Deity thereby. I say, then, that this Bridge reaches from Heaven to earth, and constitutes the union which I have made with man. . . . So the height of the Divinity, humbled to the earth, and joined with your humanity made the Bridge and reformed the road. Why was this done? In order that man might come to his true happiness with the angels. And observe that it is not enough, in order that you should have life, that My son should have made you this Bridge, unless you walk thereon.”244 “Our high Father God Almighty, which is Being,” says Lady Julian, “He knew and loved us from afore any time. Of which knowing, in His marvellous deep charity, and the foreseeing counsel of all the blessed Trinity, He willed that the Second Person should become our Mother.”245
It is of course this assertion of the quickening communication of grace to nature, of God to man — an influx of ultimate reality, possible of assimilation by all — which constitutes the strength of the Christian religion. Instead of the stony diet of the philosophers, it offers to the self hungry for the Absolute that Panis Angelorum, the vivifying principle of the world. That is to say, it gives concrete and experimental knowledge of a supreme Personality — absorption into His mystical body — instead of the artificial conviction produced by concentration on an idea. It knits up the universe; shows the phenomenal pierced in all directions by the real, the natural as the vehicle of the supernatural. It provides a solid basis for mysticism, a basis which is at once metaphysical and psychological: and shows that state towards which the world’s deepest minds have always instinctively aspired, as a part of the cosmic return through Christ to God.
“Quivi è la sapienza e la possanza
ch’ aprì le strade intra il cielo e la terra
onde fu già sì lunga disianza.”246
This is what the Christian mystics mean to express when they declare over and over again that the return to the Divine Substance, the Absolute, which is the end of the soul’s ascent, can only be made through the humanity of Christ. The Son, the Word, is the character of the Father: that in which the Ineffable Godhead knows Himself, as we only know ourselves in our own characters. He is thus a double link: the means of God’s self-consciousness, the means of man’s consciousness of God. How then, asks mystic theology, could such a link complete its attachments without some such process as that which the Incarnation dramatized in time and space? The Principle of Life is also the Principle of Restitution; by which the imperfect and broken life of sense is mended and transformed into the perfect life of spirit. Hence the title of Repairer applied by Boehme to the Second Person of the Trinity.
In the last resort, the doctrine of the Incarnation is the only safeguard of the mystics against the pantheism to which they always tend. The Unconditioned Absolute, so soon as it alone becomes the object of their contemplation, is apt to be conceived merely as Divine Essence; the idea of Personality evaporates. The union of the soul with God is then thought of in terms of absorption. The distinction between Creator and creature is obliterated and loving communion is at an end. This is probably the reason why many of the greatest contemplatives — Suso and St. Teresa are cases in point — have found that deliberate meditation upon the humanity of Christ, difficult and uncongenial as this concrete devotion sometimes is to the mystical temperament, was a necessity if they were to retain a healthy and well-balanced inner life.
Further, these mystics see in the historic life of Christ an epitome — or if you will, an exhibition — of the essentials of all spiritual life. There they see dramatized not only the cosmic process of the Divine Wisdom, but also the inward experience of every soul on her way to union with that Absolute “to which the whole Creation moves.” This is why the expressions which they use to describe the evolution of the mystical consciousness from the birth of the divine in the spark of the soul to its final unification with the Absolute Life are so constantly chosen from the Drama of Faith. In this drama they see described under veils the necessary adventures of the spirit. Its obscure and humble birth, its education in poverty, its temptation, mortification and solitude, its “illuminated life” of service
