A demon holds a book, in which are written the sins of a particular man; an Angel drops on it from a phial, a tear which the sinner had shed in doing a good action, and his sins are washed out. – Alberic, Monk of Monte-Cassino

Angels may be very excellent sort of folk in their own way, but we, poor mortals in our present state, would probably find them precious slow company. – Jerome K. Jerome
