49. The prophets say: “In Thy light we shall see light;” Ps. xxxvi. 9. and again: “Wisdom is the brightness of everlasting light, and the spotless mirror of God’s majesty, the image of His goodness.” Wis. vii. 26. See what great names are declared! “Brightness,” because in the Son the Father’s glory shines clearly: “spotless mirror,” because the Father is seen in the Son: Cf. S. John xii. 45. “image of goodness,” because it is not one body seen reflected in another, but the whole power [of the Godhead] in the Son. The word “image” teaches us that there is no difference; “expression,” that He is the counterpart of the Father’s form; and “brightness” declares His eternity. The brightness or effulgence of a body lasts as long as that body exists; seeing, then, that the Father is eternal, the Son, Who is His brightness, must be eternal also (H.). The “image” in truth is not that of a bodily countenance, not one made up of colours, nor modelled in wax, but simply derived from God, coming out from the Father, drawn from the fountainhead.
