Holy Rule Of Saint Benedict CHAPTER LXX That No One Presume to Strike Another

Let every occasion for presumption be avoided in the monastery. We decree that no one be permitted to excommunicate or to strike any one of his brethren, unless the Abbot hath given him the authority. But let those who transgress be taken to task in the presence of all, that the others may fear (cf 1 Tm 5:20).

Let all, however, exercise diligent and watchful care over the discipline of children, until the age of fifteen; but even that, within due limits and with discretion. For if anyone should presume to chastise those of more advanced years, without the command of the Abbot, or should be unduly provoked with children, let him be subject to the discipline of the Rule; because it is written: "What thou dost not wish to be done to thee, do not thou to another" (Tb 4:16).
