We think that thus we do a pious work.” And Philemon also, who published many explanations of ancient customs, shares in the knowledge of the truth; and thus he writes:— “Tell me what thoughts of God we should conceive? One, all things seeing, yet Himself unseen.” Even Orpheus, too, who introduces three hundred and sixty gods, will bear testimony 291 in my favour from the tract called Diathecæ, in which he appears to repent of his error by writing the following:— “I’ll speak to those who lawfully may hear; All others, ye profane, now close the doors! And, O Musæus, hearken thou to me, Who offspring art of the light-bringing moon. The words I tell thee now are true indeed, And if thou former thoughts of mine hast seen, Let them not rob thee of the blessed life; But rather turn the depths of thine own heart Unto that place where light and knowledge dwell. Take thou the word divine to guide thy steps; And walking well in the straight certain path, Look to the one and universal King, One, self-begotten, and the only One Of whom all things, and we ourselves, are sprung. All things are open to His piercing gaze, While He Himself is still invisible; Present in all His works, though still unseen, He gives to mortals evil out of good, Sending both chilling wars and tearful griefs; And other than the Great King there is none. The clouds for ever settle round His throne; And mortal eyeballs in mere mortal eyes Are weak to see Jove, reigning over all. He sits established in the brazen heavens Upon His throne; and underneath His feet He treads the earth, and stretches His right hand To all the ends of ocean, and around 779 Chapter II.—Testimonies to the unity of God.
