The Rule of St. Benedict - Chapter 53. The Reception Of Guests

(16) The kitchen for the abbot and guests ought to be separate, so the guests – and monasteries are never without them – need not disturb the brothers when they present themselves at unpredictable hours.
(17) Each year, two brothers who can do the work competently are to be assigned to this kitchen.
(18) Additional help should be available when needed, so that they can perform this service without grumbling. On the other hand, when the work slackens, they are to go wherever other duties are assigned them.
(19) This consideration is not for them alone, but applies to all duties in the monastery;
(20) the brothers are to be given help when it is needed, and wherever they are free, they work wherever they are assigned.

(21) The guest quarters are to be entrusted to a God-fearing brother.
(22) Adequate bedding should be available there. The house of God should be in the care of wise men who will manage it wisely.

(23) No one is to speak or associate with guests unless he is bidden;
(24) however, if a brother meets or sees a guest, he is to greet him humbly, as we have said. He asks for a blessing and continues on his way, explaining that he is not allowed to speak with a guest.
