He most truly begets, and it is most truly begotten.
BUT it will be impossible to establish this proposition, unless, in equal degree, he most truly begets, and it is most truly begotten. As the former supposition is evidently true, so the latter is necessarily most certain. Hence, it belongs to the supreme Spirit most truly to beget, and to his Word to be most truly begotten.
Chapter XLII
It is the property of the one to be most truly progenitor and Father, and of the other to be the begotten and Son.
I should certainly be glad, and perhaps able, now to reach the conclusion, that he is most truly the Father , while this Word is most truly his Son. But I think that even this question should not be neglected: whether it is more fitting to call them Father and Son, than mother and daughter, since in them there is no distinction of sex.
For, if it is consistent with the nature of the one to be the Father, and of his offspring to be the Son, because both are Spirit (Spiritus, masculine); why is it not, with equal reason, consistent with the nature of the one to be the mother, and the other the daughter, since both are truth and wisdom (veritas et sapientia, feminine)?
Or, is it because in these natures that have a difference of sex, it belongs to the superior sex to be father or son, and to the inferior to be mother or daughter? And this is certainly a natural fact in most instances, but in some the contrary is true, as among certain kinds of birds, among which the female is always larger and stronger, while the male is smaller and weaker.
At any rate, it is more consistent to call the supreme Spirit father than mother, for this reason, that the first and principal cause of offspring is always in the father. For, if the maternal cause is ever in some way preceded by the paternal, it is exceedingly inconsistent that the name mother should be attached to that parent with which, for the generation of offspring, no other cause is associated, and which no other precedes. It is, therefore, most true that the supreme Spirit is Father of his offspring. But, if the son is always more like the father than is the daughter, while nothing is more like the supreme Father than his offspring; then it is most true that this offspring is not a daughter, but a Son.
Hence, just as it is the property of the one most truly to beget, and of the other to be begotten, so it is the property of the one to be most truly progenitor, and of the other to be most truly begotten. And as the one is most truly the parent, and the other his offspring, so the one is most truly Father, and the other most truly Son.
Chapter XLIII
Consideration of the common attributes of both and the individual properties of each.
NOW that so many and so important properties of each have been discovered, whereby a strange plurality, as ineffable as it is inevitable, is proved to exist in the supreme unity, I think it most interesting to reflect, again and again, upon so unfathomable a mystery.
For observe: although it is so impossible that he who begets, and he who is begotten, are the same, and that parent and offspring are the same—so impossible that necessarily one must be the progenitor and the other the begotten, and one the Father, the other the Son; yet, here it is so necessary that he who begets and he who is begotten shall be the same, and also that parent and offspring shall be the same, that the progenitor cannot be any other than what the begotten is, nor the Father any other than the Son.
And although the one is one, and the other another, so that it is altogether evident that they are two; yet that which the one and the other are is in such a way one and the same, that it is a most obscure mystery why they are two. For, in such a way is one the Father and the other the Son, that when I speak of both I perceive that I have spoken of two; and yet so identical is that which both Father and Son are, that I do not understand why they are two of whom I have spoken.
For, although the Father separately is the perfectly supreme Spirit, and the Son separately is the perfectly supreme Spirit, yet, so are the Spirit-Father and the Spirit-Son one and the same being, that the Father and the Son are not two spirits, but one Spirit. For, just as to separate properties of separate beings, plurality is not attributed, since they are not properties of two things, so, what is common to both preserves an indivisible unity, although it belongs, as a whole, to them taken separately.
For, as there are not two fathers or two sons, but one Father and one Son, since separate properties belong to separate beings, so there are not two spirits, but one Spirit; although it belongs both to the Father, taken separately, and to the Son, taken separately, to be the perfect Spirit. For so opposite are their relations, that the one never assumes the property of the other; so harmonious are they in nature, that the one ever contains the essence of the other. For they are so diverse by virtue of the fact that the one is the Father and the other the Son, that the Father is never called the Son, nor the Son the Father; and they are so identical, by virtue of their substance, that the essence of the Son is ever in the Father, and the essence of the Father in the Son.
Chapter XLIV
How one is the essence of the other.
HENCE, even if one is called the essence of the other, there is no departure from truth; but the supreme simplicity and unity of their common nature is thus honored. For, not as one conceives of a man’s wisdom, through which man is wise, though he cannot be wise through himself, can we thus understand the statement that the Father is essence of the Son, and the Son the essence of the Father. We cannot understand that the Son is existent through the Father, and the Father through the Son, as if the one could not be existent except through the other, just as a man cannot be wise except through wisdom.
For, as the supreme Wisdom is ever wise through itself, so the supreme Essence ever exists through itself. But, the perfectly supreme Essence is the Father, and the perfectly supreme Essence is the Son. Hence, the perfect Father and the perfect Son exist, each through himself, just as each is wise through himself.
For the Son is not the less perfect essence or wisdom because he is an essence born of the essence of the Father, and a wisdom born of the wisdom of the Father; but he would be a less perfect essence or wisdom if he did not exist through himself, and were not wise through himself.
For, there is no inconsistency between the subsistence of the Son through himself, and his deriving existence from his Father. For, as the Father has essence, and wisdom, and life in himself; so that not through another’s, but through his own, essence he exists; through his own wisdom he is wise; through his own life he lives; so, by generation, he grants to his Son the possession of essence, and wisdom, and life in himself, so that not through an extraneous essence, wisdom, and life, but through his own, he subsists, is wise, and lives; otherwise, the existence of Father and Son will not be the same, nor will the Son be equal to the Father. But it has already been clearly proved how false this supposition is.
Hence, there is no inconsistency between the subsistence of the Son through himself, and his deriving existence from the Father, since he must have from the Father this very power of subsisting through himself. For, if a wise man should teach me his wisdom, which I formerly lacked, he might without impropriety be said to teach me by this very wisdom of his. But, although my wisdom would derive its existence and the fact of its being from his wisdom, yet when my wisdom once existed, it would be no other essence than its own, nor would it be wise except through itself.
Much more, then, the eternal Father’s eternal Son, who so derives existence from the Father that they are not two essences, subsists, is wise, and lives through himself. Hence, it is inconceivable that the Father should be the essence of the Son, or the Son the essence of the Father, on the ground that the one could not subsist through itself, but must subsist through the other. But in order to indicate how they share in an essence supremely simple and supremely one, it may consistently be said, and conceived, that the one is so identical with the other that the one possesses the essence of the other.
On these grounds, then, since there is obviously no difference between possessing an essence and being an essence, just as the one possesses the essence of the other, so the one is the essence of the other, that is, the one has the same existence with the other.
