Penance to be sure must be used as a tool, in due times and places, as need may be. If the flesh, being too strong, kicks against the spirit, penance takes the rod of discipline, and fast, and the cilice of many buds, and mighty vigils; and places burdens enough on the flesh, that it may be more subdued. But if the body is weak, fallen into illness, the rule of discretion does not approve of such a method.
St. Catherine of SienaWe've had enough of exhortations to be silent! Cry out with a hundred thousand tongues. I see that the world is rotten because of silence.
St. Catherine of SienaWherefore, as I have said to you, I, God, have become man, and man has become God by the union of My Divine Nature with your human nature. This greatness is given in general to all rational creatures, but, among these I have especially chosen My ministers for the sake of your salvation, so that, through them, the Blood of the humble and immaculate Lamb, My only-begotten Son, may be administered to you.
