Some of the angels, in their pride, not only thought they could overthrow God, but that they could hide their darkness.
However, without God, “even the angels, are darkness without God, because God is light.
“The angels fell, and the soul of man fell; thus they indicate to us the deep darkness of the abyss, which would have still contained the whole spiritual creation if thou hadst not said, in the beginning, “Let there be light: and there was light” — and if every obedient mind in thy heavenly city had not adhered to thee and had not reposed in thy Spirit, which moved immutable over all things mutable. Otherwise, even the heaven of heavens itself would have been a dark shadow, instead of being, as it is now, light in the Lord.”The Confessions of St Augustine
The Confessions of St Augustine
For even in the restless misery of the fallen spirits, who exhibit their own darkness when they are stripped of the garments of thy light, thou showest clearly how noble thou didst make the rational creation, for whose rest and beatitude nothing suffices save thee thyself. And certainly it is not itself sufficient for its beatitude. For it is thou, O our God, who wilt enlighten our darkness; from thee shall come our garments of light; and then our darkness shall be as the noonday. ”
