VIII.  How then was He begotten?  This Generation would have been no great thing, if you could have comprehended it who have no real knowledge even of your own generation, or at least who comprehend very little of it, and of that little you are ashamed to speak; and then do you think you know the whole?  You will have to undergo much labour before you discover the laws of composition, formation, manifestation, and the bond whereby soul is united to body,—mind to soul, and reason to mind; and movement, increase, assimilation of food, sense, memory, recollection, and all the rest of the parts of which you are compounded; and which of them belongs to the soul and body together, and which to each independently of the other, and which is received from each other.  For those parts whose maturity comes later, yet received their laws at the time of conception.  Tell me what these laws are?  And do not even then venture to speculate on the Generation of God; for that would be unsafe.  For even if you knew all about your own, yet you do not by any means know about God’s.  And if you do not understand your own, how can you know about God’s?  For in proportion as God is harder to trace out than man, so is the heavenly Generation harder to comprehend than your own.  But if you assert that because you cannot comprehend it, therefore He cannot have been begotten, it will be time for you to strike out many existing things which you cannot comprehend; and first of all God Himself.  For you cannot say what He is, even if you are very reckless, and excessively proud of your intelligence.  First, cast away your notions of flow and divisions and sections, and your conceptions of immaterial as if it were material birth, and then you may perhaps worthily conceive of the Divine Generation.  How was He begotten?—I repeat the question in indignation.  The Begetting of God must be honoured by silence.  It is a great thing for you to learn that He was begotten.  But the manner of His generation we will not admit that even Angels can conceive, much less you.  Shall I tell you how it was?  It was in a manner known to the Father Who begat, and to the Son Who was begotten.  Anything more than this is hidden by a cloud, and escapes your dim sight.
