I am come a light into the world, that whosoever believes on me should not abide in darkness.

I am come a Light into the world, &c. Christ calls Himself again and again the Light of the world, which sets forth the true faith in God, His worship, devotion towards Him, virtue, and all things which tend to our salvation, and also dispels the darkness of unbelief, idolatry, and all errors and vices, so that what the sun is in the material world, is He in the spiritual. "The word light," says S. Cyril, "indicates Godhead, for it is the property of God to be the Light of the world. For God in His Essence is spiritual, uncreate, boundless Light, from which every created light, whether spiritual or material, whether of angels or men, whether of the sun or stars or of the elements, is derived as a ray from the Sun." But it is the peculiar property of the Son that He proceeds from God the Father after the manner of a ray, and of light, according to the Nicene Creed: "Light of Light, Very God of Very God."

Therefore it is just as if He had said: "I am the Light th...
For since the Father is called by this name everywhere both in the Old (Testament) and in the New, Christ uses the same name also; therefore Paul also calls Him, Brightness Hebrews 1:3, having learned to do so from this source. And He shows here His close relationship with the Father, and that there is no separation between them, if so be that He says that faith on Him is not on Him, but passes on to the Father. And He called Himself light, because He delivers from error, and dissolves mental darkness.
