The Rule of St. Benedict

If, perchance, any difficult or impossible tasks be enjoined on a brother, let him nevertheless receive the order of him who commandeth with all meekness and obedience. If, however, he see that the gravity of the task is altogether beyond his strength, let him quietly and seasonably submit the reasons for his inability to his Superior, without pride, protest, or dissent. If, however, after his explanation the Superior still insisteth on his command, let the younger be convinced that so it is good for him; and let him obey from love, relying on the help of God.
