The Rule of St. Benedict

Let all keep their order in the monastery in such wise, that the time of their conversion and the merit of their life distinguish it, or as the Abbot hath directed. Let the Abbot not disorder the flock committed to him, nor by an arbitrary use of his power dispose of anything unjustly; but let him always bear in mind that he will have to give an account to God of all his judgments and works. Hence in the order that he hath established, or that the brethren had, let them approach for the kiss of peace, for Communion, intone the psalms, and stand in choir.

And in no place whatever let age determine the order or be a disadvantage; because Samuel and Daniel when mere boys judged the priests (cf 1 Sam. 3; Dan 13:44-62). Excepting those, therefore, whom, as we have said, the Abbot from higher motives hath advanced, or, for certain reasons, hath lowered, let all the rest take their place as they are converted: thus, for instance, let him who came into the monastery at the second hour of the day, know that he is younger than he who came at the first hour, whatever his age or dignity may be.

Children are to be kept under discipline at all times and by everyone. Therefore, let the younger honor their elders, and the older love the younger.

In naming each other let no one be allowed to address another by his simple name; but let the older style the younger brethren, brothers; let the younger, however, call their elders, fathers, by which is implied the reverence due to a father. But because the Abbot is believed to hold the place of Christ, let him be styled Lord and Abbot, not only by assumption on his part, but out of love and reverence for Christ. Let him think of this and so show himself, that he be worthy of such an honor. Wherever, then, the brethren meet each other, let the younger ask the blessing from the older; and when the older passeth by, let the younger rise and give him place to sit; and let the younger not presume to sit down with him unless his elder biddeth him to do so, that it may be done as it is written: "In honor preventing one another" (Rom 12:10).

Let children and boys take their places in the oratory and at table with all due discipline; outdoors, however, or wherever they may be, let them be under custody and discipline until they reach the age of understanding.
