Answer to Eunomius' Second Book
If, then, the lower creation which comes under our organs of sense transcends human knowledge, how can He, Who by His mere will made the worlds, be within the range of our apprehension? Surely this is vanity, and lying madness, as says the Prophet, to think it possible to comprehend the things which are incomprehensible. So may we see tiny children busying themselves in their play. For oft-times, when a sunbeam streams down upon them through a window, delighted with its beauty they throw themselves on what they see, and are eager to catch the sunbeam in their hands, and struggle with one another, and grasp the light in the clutch of their fingers, and fancy they have imprisoned the ray in them, but presently when they unclasp their hands and find that the sunbeam which they held has slipped through their fingers, they laugh and clap their hands. In like manner the children of our generation, as says the parable, sit playing in the market-places; for, seeing the power of God shining in upon their souls through the dispensations of His providence, and the wonders of His creation like a warm ray emanating from the natural sun, they marvel not at the Divine gift, nor adore Him Whom such things reveal, but passing beyond the limits of the soul's capabilities, they seek with their sophistical understanding to grasp that which is intangible, and think by their reasonings to lay hold of what they are persuaded of; but when their argument unfolds itself and discloses the tangled web of their sophistries, men of discernment see at once that what they have apprehended is nothing at all; so pettily and so childishly labouring in vain at impossibilities do they set themselves to include the inconceivable nature of God in the few syllables of the term “ungenerate,” and applaud their own folly, and imagine God to be such that human reasoning can include Him under one single term: and while they pretend to follow the teaching of the sacred writers, they are not afraid of raising themselves above them. For what cannot be shown to have been said by any of those blessed ones, any words of whose are recorded in the sacred books, these things, as says the Apostle, “understanding neither what they say, nor whereof they affirm,” they nevertheless say they know, and boast of guiding others to such knowledge. And on this account they declare that they have apprehended that God the Only-begotten is not what He is called. For to this conclusion they are compelled by their premises.
How pitiable are they for their cleverness! How wretched, how fatal is their over-wise philosophy! Who is there who goes of his own accord to the pit so eagerly as these men labour and bestir themselves to dig out their lake of blasphemy? How far have they separated themselves from the hope of the Christian! What a gulf have they fixed between themselves and the faith which saves! How far have they withdrawn themselves from Abraham the father of the faith! He indeed, if in the lofty spirit of the Apostle we may take the words allegorically, and so penetrate to the inner sense of the history, without losing sight of the truth of its facts— he, I say, went out by Divine command from his own country and kindred on a journey worthy of a prophet eager for the knowledge of God. For no local migration seems to me to satisfy the idea of the blessings which it is signified that he found. For going out from himself and from his country, by which I understand his earthly and carnal mind, and raising his thoughts as far as possible above the common boundaries of nature, and forsaking the soul's kinship with the senses—so that untroubled by any of the objects of sense his eyes might be open to the things which are invisible, there being neither sight nor sound to distract the mind in its work—“walking,” as says the Apostle, “by faith, not by sight,” he was raised so high by the sublimity of his knowledge that he came to be regarded as the acme of human perfection, knowing as much of God as it was possible for finite human capacity at its full stretch to attain. Therefore also the Lord of all creation, as though He were a discovery of Abraham, is called specially the God of Abraham. Yet what says the Scripture respecting him? That he went out not knowing whither he went, no, nor even being capable of learning the name of Him whom he loved, yet in no wise impatient or ashamed on account of such ignorance.
This, then, was the meaning of his safe guidance on the way to what he sought— that he was not blindly led by any of the means ready to hand for his instruction in the things of God, and that his mind, unimpeded by any object of sense, was never hindered from its journeying in quest of what lies beyond all that is known, but having gone by reasoning far beyond the wisdom of his countrymen, (I mean the philosophy of the Chaldees, limited as it was to the things which do appear,) and soaring above the things which are cognizable by sense, from the beauty of the objects of contemplation, and the harmony of the heavenly wonders, he desired to behold the archetype of all beauty. And so, too, all the other things which in the course of his reasoning he was led to apprehend as he advanced, whether the power of God, or His goodness, or His being without beginning, or His infinity, or whatever else is conceivable in respect to the divine nature, using them all as supplies and appliances for his onward journey, ever making one discovery a stepping-stone to another, ever reaching forth unto those things which were before, and setting in his heart, as says the Prophet, each fair stage of his advance, and passing by all knowledge acquired by his own ability as falling short of that of which he was in quest, when he had gone beyond every conjecture respecting the divine nature which is suggested by any name among all our conceptions of God, having purged his reason of all such fancies, and arrived at a faith unalloyed and free from all prejudice, he made this a sure and manifest token of the knowledge of God, viz. the belief that He is greater and more sublime than any token by which He may be known. On this account, indeed, after the ecstasy which fell upon him, and after his sublime meditations, falling back on his human weakness, “I am,” says he, “but dust and ashes,” that is to say, without voice or power to interpret that good which his mind had conceived. For dust and ashes seem to denote what is lifeless and barren; and so there arises a law of faith for the life to come, teaching those who would come to God, by this history of Abraham, that it is impossible to draw near to God, unless faith mediate, and bring the seeking soul into union with the incomprehensible nature of God. For leaving behind him the curiosity that arises from knowledge, Abraham, says the Apostle, “believed God, and it was counted unto him for righteousness.” “Now it was not written for his sake,” the Apostle says, “but for us,” that God counts to men for righteousness their faith, not their knowledge. For knowledge acts, as it were, in a commercial spirit, dealing only with what is known. But the faith of Christians acts otherwise. For it is the substance, not of things known, but of things hoped for. Now that which we have already we no longer hope for. “For what a man has,” says the Apostle, “why does he yet hope for”? But faith makes our own that which we see not, assuring us by its own certainty of that which does not appear. For so speaks the Apostle of the believer, that “he endured as seeing Him Who is invisible.” Vain, therefore, is he who maintains that it is possible to take knowledge of the divine essence, by the knowledge which puffs up to no purpose. For neither is there any man so great that he can claim equality in understanding with the Lord, for, as says David, “Who is he among the clouds that shall be compared unto the Lord?” nor is that which is sought so small that it can be compassed by the reasonings of human shallowness. Listen to the preacher exhorting not to be hasty to utter anything before God, “for God,” (says he,) “is in heaven above, and thou upon earth beneath.”
