Above all this, we have been given humility, which watches over all the virtues and is that great holy strength with which God clothed himself when he came into the world. Humility is the rampart of the virtues, the treasury of works, the saving armour and the cure for every wound. When they made fine linens, the wrought gold, and all the fittings of the Tabernacle, they covered them with sackcloth (Ex 27:9-16, Jdt 4:11). Humility is least among men but precious and glorious before God. If we acquire it we shall trample the whole force of the enemy underfoot (Luk 10:19). It is said, Whom shall I consider, if not the humble and meek? (Is 66:2).
