The Rule of St. Benedict

The vice of personal ownership must by all means be cut out in the monastery by the very root, so that no one may presume to give or receive anything without the command of the Abbot; nor to have anything whatever as his own, neither a book, nor a writing tablet, nor a pen, nor anything else whatsoever, since monks are allowed to have neither their bodies nor their wills in their own power. Everything that is necessary, however, they must look for from the Father of the monastery; and let it not be allowed for anyone to have anything which the Abbot did not give or permit him to have. Let all things be common to all, as it is written. And let no one call or take to himself anything as his own (cf Acts 4:32). But if anyone should be found to indulge this most baneful vice, and, having been admonished once and again, doth not amend, let him be subjected to punishment.
