For those who believe, no proof is necessary. For those who disbelieve, no amount of proof is sufficient.
Ignatius of LoyolaThe safest and most suitable form of penance seems to be that which causes pain in the flesh but does not penetrate to the bones, that is, which causes suffering but not sickness.
Ignatius of LoyolaJust as the commander of an army pitches his camp, studies the strength and defenses of a fortress, and then attacks it on its weakest side, in like manner, the enemy of our human nature studies from all sides our theological, cardinal, and moral virtues. Wherever he finds us weakest and most in need regarding our eternal salvation, he attacks and tries to take us by storm.
