“The light is Charity, and the measuring of this light is done to us profitably by the wisdom of God.”

Original: (la) Lex naturae […] nihil aliud est nisi lumen intellectis insitum nobis a Deo, per quod cognoscimus quid agendum et quid vitandum. Hoc lumen et hanc legem dedit Deus homini in creatione.

The Sixteenth Revelation, Chapter 83
Context: Our faith is a light by nature coming of our endless Day, that is our Father, God. In which light our Mother, Christ, and our good Lord, the Holy Ghost, leadeth us in this passing life. This light is measured discreetly, needfully standing to us in the night. The light is cause of our life; the night is cause of our pain and of all our woe: in which we earn meed and thanks of God. For we, with mercy and grace, steadfastly know and believe our light, going therein wisely and mightily.

The City of God (early 400s)
Context: For when God said, “Let there be light, and there was light,” if we are justified in understanding in this light the creation of the angels, then certainly they were created partakers of the eternal light which is the unchangeable Wisdom of God, by which all things were made, and whom we call the only-begotten Son of God; so that they, being illumined by the Light that created them, might themselves become light and be called “Day,” in participation of that unchangeable Light and Day which is the Word of God, by whom both themselves and all else were made. “The true Light, which lighteth every man that cometh into the world,” — this Light lighteth also every pure angel, that he may be light not in himself, but in God; from whom if an angel turn away, he becomes impure, as are all those who are called unclean spirits, and are no longer light in the Lord, but darkness in themselves, being deprived of the participation of Light eternal. For evil has no positive nature; but the loss of good has received the name “evil.”

In the letter I wrote to you, you will remember I said that our species will end but the light of God will not end and at that point it will invade all souls and it will all be in everyone.

Context: God is the light that illuminates the darkness, even if it does not dissolve it, and a spark of divine light is within each of us. In the letter I wrote to you, you will remember I said that our species will end but the light of God will not end and at that point it will invade all souls and it will all be in everyone.
