“The world,” he says, “knew Him not”; but they of whom the world was not worthy knew Him. And having spoken of those who knew Him not, he in a short time puts the cause of their ignorance; for he does not absolutely say, that no one knew Him, but that “the world knew him not”; that is, those persons who are as it were nailed to the world alone, and who mind the things of the world. For so Christ was wont to call them; as when He says, “O Holy Father, the world hath not known Thee.” ( c. xvii. 25.) The world then was ignorant, not only of Him, but also of His Father, as we have said; for nothing so darkens the mind as to be closely attached to present things.
