St Benedict's model for the monastic life was the family, with the abbot as father and all the monks as brothers. Priesthood was not initially an important part of Benedictine monasticism – monks used the services of their local priest. Because of this, almost all the Rule is applicable to communities of women under the authority of an abbess.
St Benedict's Rule organises the monastic day into regular periods of communal and private prayer, sleep, spiritual reading, and manual labour – ut in omnibus glorificetur Deus, "that in all [things] God may be glorified" (cf. Rule ch. 57.9). In later centuries, intellectual work and teaching took the place of farming, crafts, or other forms of manual labour for many – if not most – Benedictines.
Traditionally, the daily life of the Benedictine revolved around the eight canonical hours. The monastic timetable or Horarium would begin at midnight with the service, or "office", of Matins (today also called the Office of Readings), followed by the morning office of Lauds at 3am. Before the advent of wax candles in the 14th century, this office was said in the dark or with minimal lighting; and monks were expected to memorise everything. These services could be very long, sometimes lasting till dawn, but usually consisted of a chant, three antiphons, three psalms, and three lessons, along with celebrations of any local saints' days. Afterwards the monks would retire for a few hours of sleep and then rise at 6am to wash and attend the office of Prime. They then gathered in Chapter to receive instructions for the day and to attend to any judicial business. Then came private Mass or spiritual reading or work until 9am when the office of Terce was said, and then High Mass. At noon came the office of Sext and the midday meal. After a brief period of communal recreation, the monk could retire to rest until the office of None at 3pm. This was followed by farming and housekeeping work until after twilight, the evening prayer of Vespers at 6pm, then the night prayer of Compline at 9pm, and off to blessed bed before beginning the cycle again. In modern times, this timetable is often changed to accommodate any apostolate outside the monastic enclosure (e.g. the running of a school or parish).
Many Benedictine Houses have a number of Oblates (secular) who are affiliated with them in prayer, having made a formal private promise (usually renewed annually) to follow the Rule of St Benedict in their private life as closely as their individual circumstances and prior commitments permit.
In recent years discussions have occasionally been held concerning the applicability of the principles and spirit of the Rule of St Benedict to the secular working environment.
