That there is, then, a Word of God, and a Breath of God, the Greek, with his “innate ideas”, and the Jew, with his Scriptures, will perhaps not deny. But the dispensation as regards the Word of God, whereby He became man, both parties would perhaps equally reject, as being incredible and unfitting to be told of God. By starting, therefore, from another point we will bring these gainsayers to a belief in this fact. They believe that all things came into being by thought and skill on the part of Him Who framed the system of the universe; or else they hold views that do not conform to this opinion.
But should they not grant that reason and wisdom guided the framing of the world, they will install unreason and unskilfulness on the throne of the universe. But if this is an absurdity and impiety, it is abundantly plain that they must allow that thought and skill rule the world. Now in what has been previously said, the Word of God has been shown not to be this actual utterance of speech, or the possession of some science or art, but to be a power essentially and substantially existing, willing all good, and being possessed of strength to execute all its will; and, of a world that is good, this power appetitive and creative of good is the cause.
If, then, the subsistence of the whole world has been made to depend on the power of the Word, as the train of the argument has shown, an absolute necessity prevents us entertaining the thought of there being any other cause of the organization of the several parts of the world than the Word Himself, through whom all things in it passed into being. If any one wants to call Him Word, or Skill, or Power, or God, or anything else that is high and prized, we will not quarrel with him.
For whatever word or name be invented as descriptive of the subject, one thing is intended by the expressions, namely the eternal power of God which is creative of things that are, the discoverer of things that are not, the sustaining cause of things that are brought into being, the foreseeing cause of things yet to be. This, then, whether it be God, or Word, or Skill, or Power, has been shown by inference to be the Maker of the nature of man, not urged to framing him by any necessity, but in the superabundance of love operating the production of such a creature.
For needful it was that neither His light should be unseen, nor His glory without witness, nor His goodness unenjoyed, nor that any other quality observed in the Divine nature should in any case lie idle, with none to share it or enjoy it. If, therefore, man comes to his birth upon these conditions, namely to be a partaker of the good things in God, necessarily he is framed of such a kind as to be adapted to the participation of such good. For as the eye, by virtue of the bright ray which is by nature wrapped up in it, is in fellowship with the light, and by its innate capacity draws to itself that which is akin to it, so was it needful that a certain affinity with the Divine should be mingled with the nature of man, in order that by means of this correspondence it might aim at that which was native to it.
It is thus even with the nature of the unreasoning creatures, whose lot is cast in water or in air; each of them has an organization adapted to its kind of life, so that by a peculiar formation of the body, to the one of them the air, to the other the water, is its proper and congenial element. Thus, then, it was needful for man, born for the enjoyment of Divine good, to have something in his nature akin to that in which he is to participate. For this end he has been furnished with life, with thought, with skill, and with all the excellences that we attribute to God, in order that by each of them he might have his desire set upon that which is not strange to him.
Since, then, one of the excellences connected with the Divine nature is also eternal existence, it was altogether needful that the equipment of our nature should not be without the further gift of this attribute, but should have in itself the immortal, that by its inherent faculty it might both recognize what is above it, and be possessed with a desire for the divine and eternal life. In truth this has been shown in the comprehensive utterance of one expression, in the description of the cosmogony, where it is said that man was made “in the image of God”. For in this likeness, implied in the word image, there is a summary of all things that characterize Deity; and whatever else Moses relates, in a style more in the way of history, of these matters, placing doctrines before us in the form of a story, is connected with the same instruction.
For that Paradise of his, with its peculiar fruits, the eating of which did not afford to them who tasted thereof satisfaction of the appetite, but knowledge and eternity of life, is in entire agreement with what has been previously considered with regard to man, in the view that our nature at its beginnings was good, and in the midst of good. But, perhaps, what has been said will be contradicted by one who looks only to the present condition of things, and thinks to convict our statement of untruthfulness, inasmuch as man is seen no longer under those primeval circumstances, but under almost entirely opposite ones.
“Where is the divine resemblance in the soul? Where the body's freedom from suffering? Where the eternity of life? Man is of brief existence, subject to passions, liable to decay, and ready both in body and mind for every form of suffering.” By these and the like assertions, and by directing the attack against human nature, the opponent will think that he upsets the account that has been offered respecting man. But to secure that our argument may not have to be diverted from its course at any future stage, we will briefly discuss these points.
That the life of man is at present subject to abnormal conditions is no proof that man was not created in the midst of good. For since man is the work of God, Who through His goodness brought this creature into being, no one could reasonably suspect that he, of whose constitution goodness is the cause, was created by his Maker in the midst of evil. But there is another reason for our present circumstances being what they are, and for our being destitute of the primitive surroundings: and yet again the starting-point of our answer to this argument against us is not beyond and outside the assent of our opponents.
For He who made man for the participation of His own peculiar good, and incorporated in him the instincts for all that was excellent, in order that his desire might be carried forward by a corresponding movement in each case to its like, would never have deprived him of that most excellent and precious of all goods; I mean the gift implied in being his own master, and having a free will. For if necessity in any way was the master of the life of man, the “image” would have been falsified in that particular part, by being estranged owing to this unlikeness to its archetype.
How can that nature which is under a yoke and bondage to any kind of necessity be called an image of a Master Being? Was it not, then, most right that that which is in every detail made like the Divine should possess in its nature a self-ruling and independent principle, such as to enable the participation of good to be the reward of its virtue? Whence, then, comes it, you will ask, that he who had been distinguished throughout with most excellent endowments exchanged these good things for the worse?
The reason of this also is plain. No growth of evil had its beginning in the Divine will. Vice would have been blameless were it inscribed with the name of God as its maker and father. But the evil is, in some way or other, engendered from within, springing up in the will at that moment when there is a retrocession of the soul from the beautiful. For as sight is an activity of nature, and blindness a deprivation of that natural operation, such is the kind of opposition between virtue and vice.
It is, in fact, not possible to form any other notion of the origin of vice than as the absence of virtue. For as when the light has been removed the darkness supervenes, but as long as it is present there is no darkness, so, as long as the good is present in the nature, vice is a thing that has no inherent existence; while the departure of the better state becomes the origin of its opposite. Since then, this is the peculiarity of the possession of a free will, that it chooses as it likes the thing that pleases it, you will find that it is not God Who is the author of the present evils, seeing that He has ordered your nature so as to be its own master and free; but rather the recklessness that makes choice of the worse in preference to the better.
