The Rule of St. Benedict · 41 of 69
Chapter 45: Concerning those who make mistakes in the oratory
If any one, in saying a psalm, response, or antiphone or lesson, make a mistake: unless he humble himself there before all, giving satisfaction, he shall be subjected to greater punishment, as one who was unwilling to correct by humility that in which he had erred by neglect. But children, for such a fault, shall be whipped.
