Supernal Triad, Deity above all essence, knowledge and goodness; guide of men to Divine Wisdom; direct our path to the ultimate summit of thy mystical lore, most incomprehensible, most luminous, and most exalted, where the pure, absolute and immutable mysteries of faith are veiled in the dazzling obscurity of the secret silence, outshining all brilliance with the intensity of their darkness, and surcharging our blinded intellects with the utterly impalpable and invisible fairness of glories surpassing beauty.
The lesson is taken from the Book of the Psalms of Light:
I am in everything, I bear the skies, I am the foundation, I support the earths, I am the light that shines forth, that gives joy to the souls. I am the life of the world: I am the sap that is in all the trees: I am the sweet water beneath the sons of matter. I bore these things until I had fulfilled the will of my Father; the first man is my father whose will I have carried out. Lo, the darkness I have subdued; lo, the fire of the fountains I have extinguished, as the sphere turns hurrying round, as the sun receives the refined part of life. O soul, raise thine eyes to the height and contemplate thy bond; lo, thy fathers are calling thee. Now go aboard the ship of light and receive thy garland of glory and return to thy kingdom and rejoice with all the Aeons.
The gospel is taken from the Gospel according to St. Philip:
Man mixes with man, horse mixes with horse, mule mixes with mule. The kinds mix with those of like kind. So also spirit is wont to mix with spirit and the logos to consort with the logos and the light to consort with the light. If thou become man, men and women will love thee. If thou become spirit, the spirit will be joined to thee. If thou become logos, it is the logos which will mix with thee. If thou become light, it is the light which will consort with thee. If thou become one of those who belong above, those who belong above will find their rest in thee. If thou become like the animals and those outside or below thy place, then neither man nor spirit nor logos nor light nor those above nor those within will be able to love thee. They will not be able to find rest in thee and thou hast no part in them.
