He has no right to assert a greater and less in the Divine being. A systematic statement of the teaching of the Church
Now just as we cannot name the material of the iron from the quality now to be observed upon it (for we do not give the name of fire or ice to that which is tempered with either of these), so the moment we grant the view of these heretics, that in the case of the Life-giving Power good does not reside in It essentially, but is imparted to it only, it will become impossible to call it properly good: such a conception of it will compel us to regard it as something different, as not eternally exhibiting the good, as not in itself to be classed among genuine goods, but as such that the good is at times not in it, and is at times not likely to be in it. If these existences become good only by sharing in a something superior to themselves, it is plain that before this participation they were not good, and if, being other than good, they were then coloured by the influence of good they must certainly, if again isolated from this, be considered other than good: so that, if this heresy prevails, the Divine Nature cannot be apprehended as transmissive of good, but rather as itself needing goodness: for how can one impart to another that which he does not himself possess? If it is in a state of perfection, no abatement of that can be conceived, and it is absurd to talk of less of perfection. If on the other hand its participation of good is an imperfect one, and this is what they mean by 'less,' mark the consequence that anything in that state can never help an inferior, but will be busied in satisfying its own want: so that, according to them, Providence is a fiction, and so is the judgment and the Dispensation of the Only-begotten, and all the other works believed to be done, and still doing by Him: for He will necessarily be employed in taking care of His own good, and must abandon the supervision of the Universe.
If, then, this surmise is to have its way, namely, that our Lord is not perfected in every kind of good, it is very easy to see the conclusion of the blasphemy. This being so, our faith is vain, and our preaching vain; our hopes, which take their substance from our faith, are unsubstantial. Why are they baptized into Christ, if He has no power of goodness of His own? God forgive me for saying it! Why do they believe in the Holy Ghost, if the same account is given of Him? How are they regenerate by baptism from their mortal birth, if the regenerating Power does not possess in its own nature infallibility and independence? How can their 'vile body' be changed, while they think that He who is to change it Himself needs change, i.e. another to change Him? For as long as a nature is in defect as regards the good, the superior existence exerts upon this inferior one a ceaseless attraction towards itself: and this craving for more will never stop: it will be stretching out to something not yet grasped: the subject of this deficiency will be always demanding a supply, always altering into the grander nature, and yet will never touch perfection, because it cannot find a goal to grasp, and cease its impulse upward. The First Good is in its nature infinite, and so it follows of necessity that the participation in the enjoyment of it will be infinite also, for more will be always being grasped, and yet something beyond that which has been grasped will always be discovered, and this search will never overtake its Object, because its fund is as inexhaustible as the growth of that which participates in it is ceaseless.
Such, then, are the blasphemies which emerge from their making differences between the Persons as to the good. If on the other hand the degrees of more or less are to be understood in this case in some material sense, the absurdity of this surmise will be obvious at once, without examination in detail. Ideas of quality and distance, weight and figure, and all that goes to complete the notion of a body, will perforce be introduced along with such a surmise into the view of the Divine Nature: and where a compound is assumed, there the dissolution also of that compound must be admitted. A teaching so monstrous, which dares to discover a smaller and a larger in what is sizeless and not concrete lands us in these and suchlike conclusions, a few samples only of which are here indicated: nor indeed would it be easy to unveil all the mischief that lurks beneath it. Still the shocking absurdity that results from their blasphemous premiss will be clear from this brief notice. We now proceed to their next position, after a short defining and confirmation of our own doctrine. For an inspired testimony is a sure test of the truth of any doctrine: and so it seems to me that ours may be well guaranteed by a quotation from the divine words.
In the division of all existing things, then, we find these distinctions. There is, as appealing to our perceptions, the Sensible world: and there is, beyond this, the world which the mind, led on by objects of sense, can view: I mean the Intelligible: and in this we detect again a further distinction into the Created and the Uncreate: to the latter of which we have defined the Holy Trinity to belong, to the former all that can exist or can be thought of after that. But in order that this statement may not be left without a proof, but may be confirmed by Scripture, we will add that our Lord was not created, but came forth from the Father, as the Word with His own lips attests in the Gospel, in a manner of birth or of proceeding ineffable and mysterious: and what truer witness could be found than this constant declaration of our Lord all through the Gospel, that the Very Father was a father, not a creator, of Himself, and that He was not a work of God, but Son of God? Just as when He wished to name His connection with humanity according to the flesh, He called that phase of his being Son of Man, indicating thereby His kinship according to the nature of the flesh with her from whom He was born, so also by the title of Son he expresses His true and real relationship to the Almighty, by that name of Son showing this natural connection: no matter if there are some who, for the contradiction of the truth, do take literally and without any explanation, words used with a hidden meaning in the dark form of parable, and adduce the expression 'created,' put into the mouth of Wisdom by the author of the Proverbs, to support their perverted views. They say, in fact, that “the Lord created me” is a proof that our Lord is a creature, as if the Only-begotten Himself in that word confessed it. But we need not heed such an argument. They do not give reasons why we must refer that text to our Lord at all: neither will they be able to show that the idea of the word in the Hebrew leads to this and no other meaning, seeing that the other translators have rendered it by “possessed” or “constituted:” nor, finally, even if this was the idea in the original text, would its real meaning be so plain and on the surface: for these proverbial discourses do not show their aim at once, but rather conceal it, revealing it only by an indirect import, and we may judge of the obscurity of this particular passage from its context where he says, “When He set His throne upon the winds,” and all the similar expressions. What is God's throne? Is it material or ideal? What are the winds? Are they these winds so familiar to us, which the natural philosophers tell us are formed from vapours and exhalations: or are they to be understood in another way not familiar to man, when they are called the bases of His throne? What is this throne of the immaterial, incomprehensible, and formless Deity? Who could possibly understand all this in a literal sense?
