The Rule of St. Benedict

If a priest asketh to be received into the monastery, let consent not be granted too readily; still, if he urgently persisteth in his request, let him know that he must keep the whole discipline of the Rule, and that nothing will be relaxed in his favor, that it may be as it is written: "Friend, whereunto art thou come" (Mt 26:25)?

It may be granted him, however, to stand next after the Abbot, and to give the blessing, or to celebrate Mass, but only if the Abbot ordereth him to do so; but if he doth not bid him, let him not presume to do anything under whatever consideration, knowing that he is under the discipline of the Rule, and let him rather give examples of humility to all. But if there is a question of an appointment in the monastery, or any other matter, let him be ranked by the time of his entry into the monastery, and not by the place granted him in consideration of the priesthood.

But if a cleric, moved by the same desire, wisheth to join the monastery, let him too have a middle place, provided he promiseth to keep the Rule and personal stability.
