John Chrysostom

(Hom. xlviii. s. 2) He goes up, not to suffer, but to teach. And He goes up secretly; because, though He could have gone openly, and kept the violence and impetuosity of the Jews in check, as He had often done before; yet to do this every time, would have disclosed His divinity; and he wished to establish the fact of His incarnation, and to teach us the way of life. And He went up privately too, to shew us what we ought to do, who cannot check our persecutors. It is not said, however, in secret, but, as it were in secret; to shew that it was done as a kind of economy. For had He done all things as God, how should we of this world know what to do, when we fell into danger?
