[2.] Tell me, then, does the radiance of the sun proceed from the substance itself of the sun, or from some other source? Any one not deprived of his very senses needs must confess, that it proceeds from the substance itself. Yet, although the radiance proceeds from the sun itself, we cannot say that it is later in point of time than the substance of that body, since the sun has never appeared without its rays. Now if in the case of these visible and sensible bodies there has been shown to be something which proceeds from something else, and yet is not after that from whence it proceeds; why are you incredulous in the case of the invisible and ineffable Nature? This same thing there takes place, but in a manner suitable to That Substance. For it is for this reason that Paul too calls Him “Brightness” ( Heb. i. 3 ); setting forth thereby His being from Him and His Co-eternity. Again, tell me, were not all the ages, and every interval created by Him? Any man not deprived of his senses must necessarily confess this. There is no interval therefore between the Son and the Father; and if there be none, then He is not after, but Co-eternal with Him. For “before” and “after” are notions implying time, since, without age or time, no man could possibly imagine these words; but God is above times and ages.
