IV. And when Infinity is considered from two points of view, beginning and end (for that which is beyond these and not limited by them is Infinity), when the mind looks into the depths above, not having where to stand, and leans upon phænomena to form an idea of God it calls the Infinite and Unapproachable which it finds there by the name of Unoriginate. And when it looks into the depth below and at the future, it calls Him Undying and Imperishable. And when it draws a conclusion from the whole, it calls Him Eternal. For Eternity is neither time nor part of time; for it cannot be measured. But what time measured by the course of the sun is to us, that Eternity is to the Everlasting; namely a sort of timelike movement and interval, coextensive with Their Existence. This however is all that I must now say of God; for the present is not a suitable time, as my present subject is not the doctrine of God, but that of the Incarnation. And when I say God, I mean Father, Son, and Holy Ghost; for Godhead is neither diffused beyond These, so as to introduce a mob of gods, nor yet bounded by a smaller compass than These, so as to condemn us for a poverty stricken conception of Deity, either Judaizing to save the Monarchia, or falling into heathenism by the multitude of our gods. For the evil on either side is the same, though found in contrary directions. Thus then is the Holy of Holies, Which is hidden even from the Seraphim, and is glorified with a thrice-repeated Holy meeting in one ascription of the title Lord and God, as one of our predecessors has most beautifully and loftily reasoned out.
V. But since this movement of Self-contemplation alone could not satisfy Goodness, but Good must be poured out and go forth beyond Itself, to multiply the objects of Its beneficence (for this was essential to the highest Goodness), He first conceived the Angelic and Heavenly Powers. And this conception was a work fulfilled by His Word and perfected by His Spirit. And so the Secondary Splendours came into being, as the ministers of the Primary Splendour (whether we are to conceive of them as intelligent Spirits, or as Fire of an immaterial and incorporeal kind, or as some other nature approaching this as near as may be). I should like to say that they are incapable of movement in the direction of evil, and susceptible only of the movement of good, as being about God and illuminated with the first Rays from God (for earthly beings have but the second illumination), but I am obliged to stop short of saying that they are immovable, and to conceive and speak of them as only difficult to move, because of him who for His Splendour was called Lucifer, but became and is called Darkness through his pride; and the Apostate Hosts who are subject to him, creators of evil by their revolt against good, and our inciters.
VI. Thus then and for these reasons, He gave being to the world of thought, as far as I can reason on these matters, and estimate great things in my own poor language. Then, when His first Creation was in good order, He conceives a second world, material and visible; and this a system of earth and sky and all that is in the midst of them; an admirable creation indeed when we look at the fair form of every part, but yet more worthy of admiration when we consider the harmony and unison of the whole, and how each part fits in with every other in fair order, and all with the whole, tending to the perfect completion of the world as a Unit. This was to show that He could call into being not only a nature akin to Himself, but also one altogether alien to Him. For akin to Deity are those natures which are intellectual, and only to be comprehended by mind; but all of which sense can take cognizance are utterly alien to It; and of these the furthest removed from it are all those which are entirely destitute of soul and power of motion.
VII. Mind then and sense, thus distinguished from each other, had remained within their own boundaries, and bore in themselves the magnificence of the Creator-Word, silent praisers and thrilling heralds of His mighty work. Not yet was there any mingling of both, nor any mixture of these opposites, tokens of a greater wisdom and generosity in the creation of natures; nor as yet were the whole riches of goodness made known. Now the Creator-Word, determining to exhibit this, and to produce a single living being out of both (the invisible and the visible creation, I mean) fashions Man; and taking a body from already existing matter, and placing in it a Breath taken from Himself (which the Word knew to be an intelligent soul, and the image of God), as a sort of second world, great in littleness, He placed him on the earth, a new Angel, a mingled worshipper, fully initiated into the visible creation, but only partially into the intellectual; king of all upon earth, but subject to the King above; earthly and heavenly; temporal and yet immortal; visible and yet intellectual; halfway between greatness and lowliness; in one person combining spirit and flesh; spirit because of the favour bestowed on him, flesh on account of the height to which he had been raised; the one that he might continue to live and glorify his benefactor, the other that he might suffer, and by suffering be put in remembrance, and be corrected if he became proud in his greatness; a living creature, trained here and then moved elsewhere; and to complete the mystery, deified by its inclination to God...for to this, I think, tends that light of Truth which here we possess but in measure; that we should both see and experience the Splendour of God, which is worthy of Him Who made us, and will dissolve us, and remake us after a loftier fashion.
VIII. This being He placed in paradise— whatever that paradise may have been (having honoured him with the gift of free will, in order that good might belong to him as the result of his choice, no less than to Him Who had implanted the seeds of it)— to till the immortal plants, by which is perhaps meant the Divine conceptions, both the simpler and the more perfect; naked in his simplicity and inartificial life; and without any covering or screen; for it was fitting that he who was from the beginning should be such. And He gave Him a Law, as material for his free will to act upon. This Law was a commandment as to what plants he might partake of, and which one he might not touch. This latter was the Tree of Knowledge; not, however, because it was evil from the beginning when planted; nor was it forbidden because God grudged it to men— let not the enemies of God wag their tongues in that direction, or imitate the serpent. But it would have been good if partaken of at the proper time; for the Tree was, according to my theory, Contemplation, which it is only safe for those who have reached maturity of habit to enter upon; but which is not good for those who are still somewhat simple and greedy; just as neither is solid food good for those who are yet tender and have need of milk. But when through the devil's malice and the woman's caprice, to which she succumbed as the more tender, and which she brought to bear upon the man, as she was the more apt to persuade— alas for my weakness, for that of my first father was mine; he forgot the commandment which had been given him, and yielded to the baleful fruit; and for his sin was banished at once from the tree of life, and from paradise, and from God; and put on the coats of skins, that is, perhaps, the coarser flesh, both mortal and contradictory. And this was the first thing which he learned— his own shame— and he hid himself from God. Yet here too he makes a gain, namely death and the cutting off of sin, in order that evil may not be immortal. Thus, his punishment is changed into a mercy, for it is in mercy, I am persuaded, that God inflicts punishment.
