Whatever, therefore, we have predicated of the wisdom of God, will be appropriately applied and understood of the Son of God, in virtue of His being the Life, and the Word, and the Truth, and the Resurrection: for all these titles are derived from His power and operations, and in none of them is there the slightest ground for understanding anything of a corporeal nature which might seem to denote either size, or form, or colour; for those children of men which appear among us, or those descendants of other living beings, correspond to the seed of those by whom they were begotten, or derive from those mothers, in whose wombs they are formed and nourished, whatever that is, which they bring into this life, and carry with them when they are born.[50] But it is monstrous and unlawful to compare God the Father, in the generation of His only-begotten Son, and in the substance[51] of the same, to any man or other living thing engaged in such an act; for we must of necessity hold that there is something exceptional and worthy of God which does not admit of any comparison at all, not merely in things, but which cannot even be conceived by thought or discovered by perception, so that a human mind should be able to apprehend how the unbegotten God is made the Father of the only-begotten Son. Because His generation is as eternal and everlasting as the brilliancy which is produced from the sun. For it is not by receiving the[52] breath of life that He is made a Son, by _any outward act_, but by His own nature. 5. Let us now ascertain how those statements which we have advanced are supported by the authority of holy Scripture. The Apostle Paul says, that the only-begotten Son is the “image of the invisible God,” and “the first-born of every creature.”[53] And when writing to the Hebrews, he says of Him that He is “the brightness of His glory, and the express image of His person.”[54] Now, we find in the treatise called the Wisdom of Solomon the following description of the wisdom of God: “For she is the breath of the power of God, and the purest efflux[55] of the glory of the Almighty.”[56] Nothing that is polluted can therefore come upon her. For she is the splendour of the eternal light, and the stainless mirror of God’s working, and the image of His goodness. Now we say, as before, that Wisdom has her existence nowhere else save in Him who is the beginning of all things: from whom also is derived everything that is wise, because He Himself is the only one who is by nature a Son, and is therefore termed the Only-begotten.
