c. 391 · John Chrysostom, Homilies on the Gospel of John 9.2
Let us then restrain this swelling of the soul, let us cut up by the roots this lump of pride, if at least we would wish to be clean, and to escape the punishment appointed for the devil. For that the proud must fall under the same punishment as that (wicked) one, hear Paul declare; “Not a novice, lest being lifted up with pride, he fall into the judgment, and the snare of the devil.” What is “the judgment”? He means, into the same “condemnation,” the same punishment. How then does he say, that a man may avoid this dreadful thing? By reflecting upon his own nature, upon the number of his sins, upon the greatness of the torments in that place, upon the transitory nature of the things which seem bright in this world, differing in nothing from grass, and more fading than the flowers of spring. If we continually stir within ourselves these considerations, and keep in mind those who have walked most upright, the devil, though he strive ten thousand ways, will not be able to lift us up, nor even to trip us at all.
