11. In the third place, wisdom is called the splendour of eternal light. The force of this expression we have explained in the preceding pages, when we introduced the similitude of the sun and the splendour of its rays, and showed to the best of our power how this should be understood. To what we then said we shall add only the following remark. That is properly termed everlasting or eternal which neither had a beginning of existence, nor can ever cease to be what it is. And this is the idea conveyed by John when he says that “God is Light.” Now His wisdom is the splendour of that light, not only in respect of its being light, but also of being everlasting light, so that His wisdom is eternal and everlasting splendour. If this be fully understood, it clearly shows that the existence of the Son is derived from the Father, but not in time, nor from any other beginning, except, as we have said, from God Himself. 12. But wisdom is also called the stainless mirror of the ἐνέργεια or working of God. We must first understand, then, what the working of the power of God is. It is a sort of vigour, so to speak, by which God operates either in creation, or in providence, or in judgment, or in the disposal and arrangement of individual things, each in its season. For as the image formed in a mirror unerringly reflects all the acts and movements of him who gazes on it, so would Wisdom have herself to be understood when she is called the stainless mirror of the power and working of the Father: as the Lord Jesus Christ also, who is the Wisdom of God, declares of Himself when He says, “The works which the Father doeth, these also doeth the Son likewise.”[71] And again He says, that the Son cannot do anything of Himself, save what He sees the Father do. As therefore the Son in no respect differs from the Father in the power of His works, and the work of the Son is not a different thing from that of the Father, but one and the same movement, so to speak, is in all things, He therefore named Him a stainless mirror, that by such an expression it might be understood that there is no dissimilarity whatever between the Son and the Father. How, indeed, can those things which are said by some to be done after the manner in which a disciple resembles or imitates his master, or according to the view that those things are made by the Son in bodily material which were first formed by the Father in their spiritual essence, agree with the declarations of Scripture, seeing in the Gospel the Son is said to do not similar things, but the _same_ things in a similar manner?
