The Rule of St. Benedict · 21 of 69
Chapter 25: Concerning graver faults
That brother, moreover, who is held guilty of a graver fault shall be suspended at the same time from table and from the oratory. None of the brothers may in any way consort with him, or have speech with him. He shall be alone at the labour enjoined upon him, persisting in the struggle of penitence; knowing that terrible sentence of the Apostle who said that such a man was given over to the destruction of the flesh in order that his soul might be saved at the day of the Lord. The refection of food moreover he shall take alone, in the measure and at the time that the abbot shall appoint as suitable for him. Nor shall he be blessed by any one who passes by, nor shall any food be given him.
