We must be firmly convinced that we have nothing of our own, except our vices and sins. We must all be on our guard against pride and empty boasting and beware of worldly or natural wisdom. A worldly spirit loves to talk a lot but does nothing, striving for the exterior signs of holiness that people can see, with no desire for true piety and interior holiness of spirit.
–Saint Francis of Assisi (1181–1226)
