From her work explaining the Athanasian Creed (as translated by Nathaniel Campbell):
But God was mindful of the oath he made by the rainbow that he placed in the clouds of the sky (cf. Gen. 9:13-17) when he willed his Son—signified by the rainbow—to be born of untainted virginal nature. He overcame all of his enemies with a powerful assault, as those humans were destroyed by the water of the flood (cf. Gen. 7)—but to a new age of humankind, restored by the water of baptism, Christ appeared like a rainbow in the clouds to reign within the Church. Indeed, the Church of God was joined to the Son of God as circumcision was to the law, whose keeping was a forerunner and prefiguration of the Church. But the new age, gilded by the Church’s ornament, shall never be chided for any fault at all. Moreover, like the rainbow it will never fade from the sky, and when it will be suppressed with fear to the point that it can scarcely see through a single eye, it will again be restored in the Son of God, just as it will also be restored at the time of the son of perdition (II Thess. 2:3). The various colors of the rainbow also signify the powers and virtues of the thousands of saints—in fire’s heat chastity and continence, in purple the martyrs’ martyrdom, in hyacinth-blue the teaching of our ancestors, and in green the virtues of the saints’ good works, which come forth as beams breathed forth by the Son of God like rays from the sun.
