The Rule of Saint Benedict binds the monk to stability, obedience, and conversion of life, celibacy folded quietly into a whole reordered life
Benedict's Rule never lists chastity as a separate vow at all — it is absorbed into a broader promise to remain permanently within a particular way of life, a notably different structure than traditions that name celibacy explicitly.
Benedict of Nursia wrote his Rule for monastic communities in the sixth century, and chapter 58 sets out the process and content of monastic profession: after a lengthy trial period, a monk vows stability, remaining in this one community for life, conversatio morum, sometimes translated fidelity to monastic life or conversion of life, and obedience. Celibacy is not named as its own vow — it is assumed as part of what conversatio morum entails, folded into a total reordering of daily existence rather than singled out as a discrete promise about sex. This structural choice matters: where some traditions treat continence as the central vow with everything else supporting it, Benedict treats it as one implication among many of a life stabilized in one place, under one rule, with one community, for good. The effect is a monasticism where chastity is sustained less by its own vow than by the surrounding architecture of obedience and permanence.
