Nor is preparation all that is wanted. Science is impossible without experiment, and experiment is the lower analogue of what in religion is called experience. As experiment alone gives certainty in the one case, so does experience alone in the other. And it is only the man who has undergone such experience, with all its imperative demands upon his whole character and life, that can justly expect satisfaction of his religious doubts and needs; while only those who, like S. Paul or S. Augustine, have experienced it in an exceptional degree, are entitled to speak with authority upon the things to which it leads. Here again a human analogy may help us. For in studying a human character there are different planes upon which we may approach it. There are the external aspects of the man, the fashion of his garments, the routine of his life, the regulation of his time, his official habits; all which, it may be noted in passing, in the case of a great character, are uniform, not because they were not once the free creation of his will, but because he knows the practical value of uniformity in all such things; and all these externals are open to the observation even of a stranger. Then there are the man's thoughts, which may be withheld or revealed at his pleasure; and these can only be understood by kindred minds, who have been trained to understand them. Lastly, there are his will and affections, the region of his motives, the secret chamber in which his real personality resides; and these are only known to those intimate friends and associates whose intuition is quickened by the sympathy of love. Now all these stages are gone through in the formation of a friendship. First we are struck by a man's appearance, and so led to listen to his conversation, and thence to make his acquaintance, and at last to become his friend. And so with the knowledge of God. The man of science, as such, can discover the uniformities of His action in external nature. The moral philosopher will further see that these actions 'make for righteousness' and that there is a moral law. But it is only to the spiritual yearning of our whole personality that He reveals Himself as a person. This analogy will make the Christian position intelligible; but for Christians it is more than an analogy. It is simply a statement of facts. For, to Christians, the Incarnation is the final sanction of 'anthropomorphism,' revealing the Eternal Word as strictly a Person, in the ordinary sense and with all the attributes which we commonly attach to the name[210].
