Lowliness of Mind by St. John Chrysostom

Taken from St. John Chrysostom's Homily on Lowliness of Mind:

Knowing therefore these things, beloved even if we should have mounted to the very pinnacle of virtue, let us consider ourselves last of all; having learned that pride is able to cast down even from the heavens themselves him who takes not heed, and humbleness of mind to bear up on high from the very abyss of sins him who knows how to be sober.
For this it was that placed the publican before the Pharisee; whereas that, pride I mean and an overweening spirit, surpassed even an incorporeal power, that of the devil; while humbleness of mind and the acknowledgment of his own sins committed brought the robber into Paradise before the Apostles. Now if the confidence which they who confess their own sins effect for themselves is so great, they who are conscious to themselves of many good qualities, yet humble their own souls, how great crowns will they not win.
For when sinfulness be put together with humbleness of mind it runs with such ease as to pass and out-strip righteousness combined with pride. If therefore thou have put it to with righteousness, whither will it not reach? through how many heavens will it not pass? By the throne of God itself surely it will stay its course; in the midst of the angels, with much confidence.
On the other hand if pride, having been yoked with righteousness, by the excess and weight of its own wickedness had strength enough to drag down its confidence; if it be put together with sinfulness, into how deep a hell will it not be able to precipitate him who has it?
These things I say, not in order that we should be careless of righteousness, but that we should avoid pride; not that we should sin, but that we should be sober-minded. For humbleness of mind is the foundation of the love of wisdom which pertains to us. Even if thou shouldest have built a superstructure of things innumerable; even if almsgiving, even if prayers, even if fastings, even if all virtue; unless this have first been laid as a foundation, all will be built upon it to no purpose and in vain; and it will fall down easily, like that building which had been placed on the sand.
For there is no one, no one of our good deeds, which does not need this; there is no one which separate from this will be able to stand. But even if thou shouldest mention temperance, even if virginity, even if despising of money, even if anything whatever, all are unclean and accursed and loathsome, humbleness of mind being absent.
Everywhere therefore let us take her with us, in words, in deeds, in thoughts, and with this let us build these (graces).
