In Christianity, humility is seen as annexed to the cardinal virtue of temperance as a potential part, because temperance includes all those virtues that refrain or express the inordinate movements of our desires or appetites. The virtue of humility may be defined: "A quality by which a person considering his own defects has a humble opinion of himself and willingly submits himself to God and to others for God's sake." St. Bernard defines it: "A virtue by which a man knowing himself as he truly is, abases himself." These definitions coincide with that given by St. Thomas Aquinas: "The virtue of humility", he says, "Consists in keeping oneself within one's own bounds, not reaching out to things above one, but submitting to one's superior" (Summa Contra Gent., bk. IV, ch. lv, tr. Rickaby). Humility is said to be the foundation of the spiritual edifice, but in a sense inferior to that in which faith is called its foundation. Humility is the first virtue inasmuch as it removes the obstacles to faith -- per modum removens prohibens, as St. Thomas says. It removes pride and makes a man subject to and a fit recipient of grace according to the words of St. James: "God resisteth the proud, and giveth his grace to the humble" (James 4:6). http://en.wikipedia.org/wiki/Humility#Humility_in_Christianity (Read More) It seems pretty important. :)
