It will presently be time to bring to their own recollection the method of this argument. Suffice it first to say this. There is no faculty in human nature adequate to the full comprehension of the divine essence. It may be that it is easy to show this in the case of human capacity alone, and to say that the incorporeal creation is incapable of taking in and comprehending that nature which is infinite will not be far short of the truth, as we may see by familiar examples; for as there are many and various things that have fleshly life, winged things, and things of the earth, some that mount above the clouds by virtue of their wings, others that dwell in hollows or burrow in the ground, on comparing which it would appear that there was no small difference between the inhabitants of air and of land; while, if the comparison be extended to the stars and the fixed circumference, it will be seen that what soars aloft on wings is not less widely removed from heaven than from the animals that are on the earth; so, too, the strength of angels compared with our own seems preeminently great, because, undisturbed by sensation, it pursues its lofty themes with pure naked intelligence. Yet, if we weigh even their comprehension with the majesty of Him Who really is, it may be that if any one should venture to say that even their power of understanding is not far superior to our own weakness, his conjecture would fall within the limits of probability, for wide and insurmountable is the interval that divides and fences off uncreated from created nature. The latter is limited, the former not. The latter is confined within its own boundaries according to the pleasure of its Maker. The former is bounded only by infinity. The latter stretches itself out within certain degrees of extension, limited by time and space: the former transcends all notion of degree, baffling curiosity from every point of view. In this life we can apprehend the beginning and the end of all things that exist, but the beatitude that is above the creature admits neither end nor beginning, but is above all that is connoted by either, being ever the same, self-dependent, not travelling on by degrees from one point to another in its life; for there is no participation of other life in its life, such that we might infer end and beginning; but, be it what it may, it is life energizing in itself, not becoming greater or less by addition or diminution. For increase has no place in the infinite, and that which is by its nature passionless excludes all notion of decrease. And as, when looking up to heaven, and in a measure apprehending by the visual organs the beauty that is in the height, we doubt not the existence of what we see, but if asked what it is, we are unable to define its nature, but we simply admire as we contemplate the overarching vault, the reverse planetary motion [1078] , the so-called Zodiac graven obliquely on the pole, whereby astronomers observe the motion of bodies revolving in an opposite direction, the differences of luminaries according to their magnitude, and the specialities of their rays, their risings and settings that take place according to the circling year ever at the same seasons undeviatingly, the conjunctions of planets, the courses of those that pass below, the eclipses of those that are above, the obumbrations of the earth, the reappearance of eclipsed bodies, the moon's multiform changes, the motion of the sun midway within the poles, and how, filled with his own light, and crowned with his encircling beams, and embracing all things in his sovereign light, he himself also at times suffers eclipse (the disc of the moon, as they say, passing before him), and how, by the will of Him Who has so ordained, ever running his own particular course, he accomplishes his appointed orbit and progress, opening out the four seasons of the year in succession; we, as I say, when we contemplate these phenomena by the aid of sight, are in no doubt of their existence, though we are as far from comprehending their essential nature as if sight had not given us any glimpse whatever of what we have seen; and even so, with regard to the Creator of the world, we know that He exists, but of His essential nature we cannot deny that we are ignorant. But, boasting as they do that they know these things, let them first tell us about the things of inferior nature; what they think of the body of the heavens, of the machinery which conveys the stars in their eternal courses, or of the sphere in which they move; for, however far speculation may proceed, when it comes to the uncertain and incomprehensible it must stop. For though any one say that another body, like in fashion (to that body of the heavens), fitting to its circular shape, checks its velocity, so that, ever turning in its course, it revolves conformably to that other upon itself, being retained by the force that embraces it from flying off at a tangent, yet how can he assert that these bodies will remain unspent by their constant friction with each other? And how, again, is motion produced in the case of two coeval bodies mutually conformed, when the one remains motionless (for the inner body, one would have thought, being held as in a vice by the motionlessness of that which embraces it, will be quite unable to act); and what is it that maintains the embracing body in its fixedness, so that it remains unshaken and unaffected by the motion of that which fits into it? And if in restless curiosity of thought we should conceive of some position for it that should keep it stationary, we must go on in logical consistency to search for the base of that base, and of the next, and of the next, and so on, and so the inquiry, proceeding from like to like, will go on to infinity, and end in helpless perplexity, still, even when some body has been put for the farthest foundation of the system of the universe, reaching after what is beyond, so that there is no stopping in our inquiry after the limit of the embracing circles. But not so, say others: but (according to the vain theory of those who have speculated on these matters) there is an empty space spread over the back of the heavens, working in which vacuum the motion of the universe revolves upon itself, meeting with no resistance from any solid body capable of retarding it by opposition and of checking its course of revolution. What, then, is that vacuum, which they say is neither a body nor an idea? How far does it extend, and what succeeds it, and what relation exists between the firm, resisting body, and that void and unsubstantial one? What is there to unite things so contrary by nature? and how can the harmony of the universe consist out of elements so incongruous; and what can any one say of Heaven itself? That it is a mixture of the elements which it contains, or one of them, or something else beside them? What, again, of the stars themselves? whence comes their radiance? what is it and how is it composed? and what is the reason of their difference in beauty and magnitude? and the seven inner orbs revolving in an opposite direction to the motion of the universe, what are they, and by what influence are they propelled? Then, too, what is that immaterial and ethereal empyrean, and the intermediate air which forms a wall of partition between that element in nature which gives heat and consumes, and that which is moist and combustible? And how does earth below form the foundation of the whole, and what is it that keeps it firmly in its place? what is it that controls its downward tendency? If any one should interrogate us on these and such-like points, will any of us be found so presumptuous as to promise an explanation of them? No! the only reply that can be given by men of sense is this:--that He Who made all things in wisdom can alone furnish an account of His creation. For ourselves, "through faith we understand that the worlds were framed by the word of God," as saith the Apostle [1079] .
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 saith the Prophet [1080] , 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 saith 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 saith the Apostle, "understanding neither what they say, nor whereof they affirm [1081] ," 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 [1082] . 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 saith 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 saith 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.
