2 For the son of thunder, the beloved of Christ, the pillar of the Churches throughout the world, who holds the keys of heaven, who drank the cup of Christ, and was baptized with His baptism, who lay upon his Master's bosom with much confidence, this man comes forward to us now; not as an actor of a play, not hiding his head with a mask, (for he has another sort of words to speak,) nor mounting a platform, nor striking the stage with his foot, nor dressed out with apparel of gold, but he enters wearing a robe of inconceivable beauty.
For he will appear before us having “put on Christ”, having his beautiful “feet shod with the preparation of the Gospel of peace”; wearing a girdle not about his waist, but about his loins, not made of scarlet leather nor daubed outside with gold, but woven and composed of truth itself. Now will he appear before us, not acting a part, (for with him there is nothing counterfeit, nor fiction, nor fable,) but with unmasked head he proclaims to us the truth unmasked; not making the audience believe him other than he is by carriage, by look, by voice, needing for the delivery of his message no instruments of music, as harp, lyre, or any other the like, for he effects all with his tongue, uttering a voice which is sweeter and more profitable than that of any harper or any music.
All heaven is his stage; his theater, the habitable world; his audience, all angels; and of men as many as are angels already, or desire to become so, for none but these can hear that harmony aright, and show it forth by their works; all the rest, like little children who hear, but what they hear understand not, from their anxiety about sweetmeats and childish playthings; so they too, being in mirth and luxury, and living only for wealth and power and sensuality, hear sometimes what is said, it is true, but show forth nothing great or noble in their actions through fastening themselves for good to the clay of the brickmaking.
By this Apostle stand the powers from above, marveling at the beauty of his soul, and his understanding, and the bloom of that virtue by which he drew unto him Christ Himself, and obtained the grace of the Spirit. For he has made ready his soul, as some well-fashioned and jeweled lyre with strings of gold, and yielded it for the utterance of something great and sublime to the Spirit.
