If it happen that something hard or impossible be laid upon any brother, let him receive the command of his superior with all docility and obedience. But if he see that the weight of the burden altogether exceeds the measure of his strength, let him explain the reasons of his incapacity to his superior calmly and in due season, without pride, obstinacy or contradiction. If after his representations the superior still persist in his decision and command, let the subject know that this is expedient for him, and let him obey out of love, trusting in the assistance of God.
