All that is done by obedience is meritorious . . . It is obedience, which, by the light of Faith, puts self-will to death, and causes the obedient man to despise his own will and throw himself into the arms of his superior … Placed in the bark of obedience, he passes happily through the stormy sea of this life, in peace of soul and tranquility of heart. Obedience and faith disperse darkness; he is strong because he has no longer any weakness or fears, for self-will, which is the cause of inordinate fear and weakness, has been destroyed.
— Saint Catherine of Siena
