The Rule of St. Benedict · 65 of 69
Chapter 69: That, in the monastery, one shall not presume to defend another
It is to be especially guarded against lest, on any occasion, one monk presume to defend another in the monastery, or to protect him as it were: even though they be joined by some nearness of relationship. Nor in any way shall the monks presume to do this; for thence can arise most grave occasion for scandals. But if any one transgress these commands, he shall be most severely punished.
