The Rule of St. Benedict - Chapter 24. Degrees Of Excommunication

(1) There ought to be due proportion between the seriousness of a fault and the measure of excommunication or discipline.
(2) The abbot determines the gravity of faults.

(3) If a brother is found guilty of less serious faults, he will not be allowed to share the common table.
(4) Anyone excluded from the common table will conduct himself as follows: in the oratory he will not lead a psalm or a refrain nor will he recite a reading until he has made satisfaction,
(5) and he will take his meals alone, after the brothers have eaten.
(6) For instance, if the brothers eat at noon, he will eat in mid-afternoon; if the brothers eat in mid-afternoon, he will eat in the evening,
(7) until by proper satisfaction he gains pardon.
