That was the true Light, that lights every man that comes into the world.
All Commentaries on John 1:9 Go To John 1
Augustine of Hippo
AD 430
What Light it is to which John bears witness, he shows himself, saying, That was the true Light.
Wherefore is there added, true? Because man enlightened is called light, but the true Light is that which lightens. For our eyes arecalled lights, and yet, without a lamp at night, or the sun by day, these lights are open to no purpose. Wherefore he adds: which lightens every man: but if every man, then John himself. He Himself then enlightened the person, by whom He wished Himself to be pointed out. Andjust as we may often, from the reflection of the sun’s rays on some object, know the sun to be risen, though we cannot fool; at the sun itself; as even feeble eyes can look at an illuminated wall, or some object of that kind: even so, those to whom Christ came, being too weak tobehold Him, He threw His rays upon John; John confessed the illumination, and so the illuminator Himself was discovered. It is said, that comes into the world. Had man not departed from Him, he had not had to be enlightened; but therefore is he to be here enlightened, because he departed thence, when the might have been enlightened.
Or the words, lightens every man, may be understood to mean, not that there is no one who is not enlightened, but that no one is enlightened except by Him.
