The Rule of St. Benedict

Let a wise old man be placed at the door of the monastery, one who knoweth how to take and give an answer, and whose mature age doth not permit him to stray about.

The porter should have a cell near the door, that they who come may always find one present from whom they may obtain an answer. As soon as anyone knocketh or a poor person calleth, let him answer, "Thanks be to God," or invoke a blessing, and with the meekness of the fear of God let him return an answer speedily in the fervor of charity. If the porter hath need of assistance, let him have a younger brother.

If it can be done, the monastery should be so situated that all the necessaries, such as water, the mill, the garden, are enclosed, and the various arts may be plied inside of the monastery, so that there may be no need for the monks to go about outside, because it is not good for their souls. But we desire that this Rule be read quite often in the community, that none of the brethren may excuse himself of ignorance.
