Humility is bedrock…

Humility is to charity what the foundation is to a building. Digging the foundation is not building the house, yet it is the preliminary, indispensable work, the condition sine qua non. The deeper, and firmer it is, the better the house will be and the greater assurance of stability it will have… Humility is the firm bedrock upon which every Christian should build the edifice of his spiritual life….Humility forms the foundation of charity by emptying the soul of pride, arrogance, disordered love of self and of one’s own excellence, and by replacing them with the love of God and our neighbor.
–Gabriel of St. Mary Magdalen (1893-1953)

Humility consists in…

Humility consists in considering oneself to be nothing in all circumstances, cutting off one’s will in all things, accusing oneself of everything, and bearing without confusion that which befalls him from without. Such is true humility, in which vainglory finds no place. A humble man doesn’t need to try to show his humility in words, nor does he need to make himself do humble deeds, for both of these lead to vainglory, hinder progress, and cause more harm than good. But when they command anything, it is necessary not to contradict, but to fulfill it with obedience. This is what leads to success.
–Saint John the Prophet (Sixth Century)
