The Rule of St. Benedict - Chapter 63. Community Rank

(10) The younger monks, then, must respect their seniors, and the seniors must love all their juniors.
(11) When they address one another, no one should be allowed to do so simply by name;
(12) rather, the seniors call the younger monks "brother" and the younger monks call their seniors "nonnus", which is translated as "venerable father."
(13) But the abbot, because we believe that he holds the place of Christ, is to be called "lord" and "abbot," not for any claim of his own, but out of honor and love for Christ.
(14) He, for his part, must reflect on this, and in his behavior show himself worthy of such honor.

(15) Wherever brothers meet, the junior asks his senior for a blessing.
(16) When an older monk comes by, the younger rises and offers him a seat, and does not presume to sit down unless the older bids him.
(17) In this way, they do what the words of Scripture say, "They should each try to be the first to show respect to the other," (Rom 12:10).

(18) In the oratory and at table, small boys and youths are kept in rank and under discipline.
(19) Outside or anywhere else, they should be supervised and controlled until they are old enough to be responsible.
