John 1:9

That was the true Light. — The right rendering of this verse is uncertain. It would, probably, give a better sense to translate it, The true Light which lighteth every man was coming into the world, i.e., was manifesting itself at the time when John was bearing witness and men were mistaking the lamp for the light. (Comp. John 5:35, Note.)

The true Light was not “true” as opposed to “false,” but “true” as answering to the perfect ideal, and as opposed to all more or less imperfect representations. The meaning of the Greek is quite clear. The difficulty arises from the fact that in English there is but one word to represent the two ideas. The word for the fuller meaning of “ideally true” is not confined to St. John, but is naturally of very frequent recurrence in his writings. The adjective is used nine times in this Gospel, and not at all in the other three. A comparison of the passages will show how important it is to get a right conception of what the word means, and will help to give it. (See John 4:23; John 4:37; John 6:32; John 7:28; John 8:16; John 15:1; John 17:3; John 19:35.) But, as ideally true, the Light was not subject to the changing conditions of time and space, but was and is true for all humanity, and “lighteth every man.”
