THIS little volume is a contribution to a "Library of Devotion," and in the body of the work the reader will be seldom troubled by any abstruse philosophising. I have thought it necessary to give, in this Introduction, a short account of Eckhart's system, but the extracts which follow are taken mainly from his successors, in whom the speculative tendency is weaker and less original, while the religious element is stronger and more attractive. It is, after all, as guides to holiness that these mystics are chiefly important to us. This side of their life's work can never be out of date, for the deeper currents of human nature change but little; the language of the heart is readily understood everywhere and at all times. The differences between Catholic and Protestant are hardly felt in the keen air of these high summits. It was Luther himself who discovered the "Theologia Germanica" and said of it that, "next to the Bible and St Augustine, no book hath ever come into my hands whence I have learnt or would wish to learn more of what God and Christ and man and all things are. I thank God that I have heard and found my God in the German tongue, as I have not yet found Him in Latin, Greek, or Hebrew." The theology of these mystics takes us straight back to the Johannine doctrine of Christ as the all-pervading Word of God, by whom all things were made and in whom all things hold together. He is not far from any one of us if we will but seek Him where He is to be found--in the innermost sanctuary of our personal life. In personal religion this means that no part of revelation is to be regarded as past, isolated, or external. "We should mark and know of a very truth," says the author of the "Theologia Germanica," "that all manner of virtue and goodness, and even the eternal Good which is God Himself, can never make a man virtuous, good, or happy, so long as it is outside the soul." In the same spirit Jacob Bšhme, 250 years later, says: "If the sacrifice of Christ is to avail for me, it must be wrought in me." Or, as his English admirer, William Law, puts it: "Christ given for us is neither more nor less than Christ given into us. He is in no other sense our full, perfect, and sufficient Atonement than as His nature and spirit are born and formed in us." The whole process of redemption must in a sense be reenacted in the inner life of every Christian. And as Christ emptied Himself for our sakes, so must we empty ourselves of all self-seeking. "When the creature claimeth for its own anything good, such as life, knowledge, or power, and in short whatever we commonly call good, as if it were that, or possessed that--it goeth astray." Sin is nothing else but self-assertion, self-will. "Be assured," says the "Theologia Germanica," "that he who helpeth a man to his own will, helpeth him to the worst that he can." He, therefore, who is "simply and wholly bereft of self" is delivered from sin, and God alone reigns in his inmost soul.
