This first adventure brought the boy Ruysbroeck to a home so perfectly fitted to his needs, that it might seem as though some secret instinct, some overshadowing love, had indeed guided his steps. His uncle, John Hinckaert, at this time about forty years of age, had lately been converted—it is said by a powerful sermon—from the comfortable and easy-going life of a prosperous ecclesiastic to the austere quest of spiritual perfection. He had distributed his wealth, given up all self-indulgence, and now, with another and younger Canon of the Cathedral named Francis van Coudenberg, lived in simplest, poorest style a dedicated life of self-denial, charity and prayer. He received his runaway nephew willingly. Perhaps he saw in this strange and eager child, suddenly flung upon his charity, an opportunity for repairing some at least amongst the omissions of his past—that terrible wreck of wasted years which torments the memory of those who are converted in middle life. His love and remorse might spend themselves on this boy. He might make of him perhaps all that he now longed to be, but could never wholly achieve: a perfect servant of the Eternal Goodness, young, vigorous, ardent, completely responsive to the touch of God.

Ruysbroeck, then, found a home soaked in love, governed by faith, renunciation, humility; a forcing-house of the spiritual life. In the persons of these two grown men, who had given up all outward things for the sake of spiritual realities, he was brought face to face—and this in his most impressionable years—with the hard facts, the concrete sacrifices, the heroic life of deliberate mortification, which underlay the lovely haunting vision, the revelation of the Divine beauty and love that had possessed him. No lesson is of higher value to the natural mystic than this. The lovers of Ruysbroeck should not forget how much they owe to the men who received, loved, influenced, educated the brilliant wayward and impressionable child. His attainment is theirs. His mysticism is rooted in their asceticism; a flower directly dependent for its perfection on that favouring soil. Though his achievement, like that of all men of genius, is individual, and transcends the circumstances and personalities which surround it; still, from those circumstances and personalities it takes its colour. It represents far more than a personal and solitary experience. Behind it lies the little house in Brussels, the supernatural atmosphere which filled it, and the fostering care of the two men whose life of external and deliberate poverty only made more plain the richness of the spirits who could choose, and remain constant to, this career of detachment and love.

The personal influence of Hinckaert and Coudenberg, the moral disciplines and perpetual self-denials of the life which he shared with them, formed the heart of Ruysbroeck’s education; helping to build up that manly and sturdy character which gave its special temper to his mystical outlook. Like so many children destined to greatness, he was hard to educate in the ordinary sense; uninterested in general knowledge, impatient of scholastic drudgery. Nothing which did not minister to his innate passion for ultimates had any attraction for him. He was taught grammar with difficulty; but on the other hand his astonishing aptitude for religious ideas, even of the most subtle kind, his passionate clear vision of spiritual things, was already so highly developed as to attract general attention; and his writings are sufficient witness to the width and depth of his theological reading. With such tastes and powers as these, and brought up in such a household, governed by religious enthusiasms and under the very shadow of the Cathedral walls, it was natural that he should wish to become a priest; and in 1317 he was ordained and given, through the influence of his uncle, a prebend in St. Gudule.

Now a great mystic is the product not merely of an untamed genius for the Transcendent, but of a moral discipline, an interior education, of the most strenuous kind. All the varied powers and tendencies of a nature which is necessarily strong and passionate, must be harnessed, made subservient to this one central interest. The instinctive egotism of the natural man—never more insidious than when set upon spiritual things—must be eradicated. So, behind these few outward events of Ruysbroeck’s adolescence, we must discern another growth; a perpetual interior travail, a perpetual slow character-building always going forward in him, as his whole personality is moulded into that conformity to the vision seen which prepares the way of union, and marks off the mystical saint from the mere adept of transcendental things. We know from his writings how large a part such moral purifications, such interior adjustments, played in his concept of the spiritual life; and the intimacy with which he describes each phase in the battle of love, each step of the spiritual ladder, the long process of preparation in which the soul adorns herself for the ‘spiritual marriage,’ guarantees to us that he has himself trodden the path which he maps out. That path goes the whole way from the first impulse of ‘goodwill,’ of glad acquiescence in the universal purpose, through the taming of the proud will to humility and suppleness, and of the insurgent heart to gentleness, kindness, and peace, to that last state of perfect charity in which the whole spirit of man is one will and one love with God.

Though his biographers have left us little material for a reconstruction of his inner development, we may surely infer something of the course which it followed from the vividly realistic descriptions in The Kingdom of Lovers and The Spiritual Marriage. Personal experience underlies the wonderful account of the ascent of the Spiritual Sun in the heavens of consciousness; the rapture, wildness and joy, the ‘fever of love’ which fulfils the man who feels its light and heat. Experience, too, dictates these profound passages which deal with the terrible spiritual reaction when the Sun declines in the heavens, and man feels cold, dead, and abandoned of God. Through these phases, at least, Ruysbroeck had surely passed before his great books came to be written.

One or two small indications there are which show us his progress on the mystic way, the development in him of those secondary psychic characters peculiar to the mystical type. It seems that by the time of his ordination that tendency to vision which often appears in the earliest youth of natural mystics, was already established in him. Deeply impressed by the sacramental side of Catholicism, and finding in it throughout his life a true means of contact with the Unseen, the priesthood was conceived by him as bringing with it a veritable access of grace; fresh power poured in on him from the Transcendent, an increase of strength wherewith to help the souls of other men. This belief took, in his meditations, a concrete and positive form. Again and again he saw in dramatic vision the soul specially dear to him, specially dependent on him—that of his mother, who had lately died in the Brussels Béguinage—demanding how long she must wait till her son’s ordination made his prayers effectual for her release from Purgatory. At the moment in which he finished saying his first Mass, this vision returned to him; and he saw his mother’s spirit, delivered from Purgatory by the power of the sacrifice which he had offered, entering into Heaven—an experience originating in, and giving sharp dramatic expression to, that sense of new and sacred powers now conferred on him, which may well at such a moment have flooded the consciousness of the young priest. This story was repeated to Pomerius by those who had heard it from Ruysbroeck himself; for “he often told it to the brothers.”

For twenty-six years—that is to say, until he was fifty years of age—Ruysbroeck lived in Brussels the industrious and inconspicuous life of a secular priest. It was not the solitude of the forest, but the normal, active existence of a cathedral chaplain in a busy capital city which controlled his development during that long period, stretching from the very beginnings of manhood to the end of middle age; and it was in fact during these years, and in the midst of incessant distractions, that he passed through the great oscillations of consciousness which mark the mystic way. It is probable that when at last he left Brussels for the forest, these oscillations were over, equilibrium was achieved; he had climbed ‘to the summits of the mount of contemplation.’ It was on those summits that he loved to dwell, absorbed in loving communion with Divine Reality; but his career fulfilled that ideal of a synthesis of work and contemplation, an acceptance and remaking of the whole of life, which he perpetually puts before us as the essential characteristic of a true spirituality. No mystic has ever been more free from the vice of other-worldliness, or has practised more thoroughly and more unselfishly the primary duty of active charity towards men which is laid upon the God-possessed.

The simple and devoted life of the little family of three went on year by year undisturbed; though one at least was passing through those profound interior changes and adventures which he has described to us as governing the evolution of the soul, from the state of the ‘faithful servant’ to the transfigured existence of the ‘God-seeing man.’ Ruysbroeck grew up to be a simple, dreamy, very silent and totally unimpressive person, who, ‘going about the streets of Brussels with his mind lifted up into God,’ seemed a nobody to those who did not know him. Yet not only a spiritual life of unequalled richness, intimacy and splendour, but a penetrating intellect, a fearless heart, deep knowledge of human nature, remarkable powers of expression, lay behind that meek and unattractive exterior. As Paul’s twelve years of quiet and subordinate work in Antioch prepared the way of his missionary career; so during this long period of service, the silent growth of character, the steady development of his mystical powers, had gone forward in Ruysbroeck. When circumstances called them into play he was found to be possessed of an unsuspected passion, strength and courage, a power of dealing with outward circumstances, which was directly dependent on his inner life of contemplation and prayer.

The event into which the tendencies of this stage of his development crystallised, is one which seems perhaps inconsistent with the common idea of the mystical temperament, with its supposed concentration on the Eternal, its indifference to temporal affairs. As his childhood was marked by an exhibition of adventurous love, so his manhood was marked by an exhibition of militant love; of that strength and sternness, that passion for the true, which—no less than humility, gentleness, peace—is an integral part of that paradoxical thing, the Christian character.

The fourteenth century, like all great spiritual periods, was a century fruitful in mystical heresies as well as in mystical saints. In particular, the extravagant pantheism preached by the Brethren of the Free Spirit had become widely diffused in Flanders, and was responsible for much bad morality as well as bad theology; those on whom the ‘Spirit’ had descended believing themselves to be already divine, and emancipated from obedience to all human codes of conduct. Soon after Ruysbroeck came as a boy to Brussels, a woman named Bloemardinne placed herself at the head of this sect, and gradually gained extraordinary influence. She claimed supernatural and prophetic powers, was said to be accompanied by two Seraphim whenever she went to the altar to receive Holy Communion, and preached a degraded eroticism under the title of ‘Seraphic love,’ together with a quietism of the most exaggerated and soul-destroying type. All the dangers and follies of a false mysticism, dissociated from the controlling influence of tradition and the essential virtue of humility, were exhibited in her. Against this powerful woman, then at the height of her fame, Ruysbroeck declared war; and prosecuted his campaign with a violence and courage which must have been startling to those who had regarded him only as a shy, pious, rather negligible young man. The pamphlets which he wrote against her are lost; but the passionate denunciations of pantheism and quietism scattered through his later works no doubt have their origin in this controversy, and represent the angle from which his attacks were made.
