§1. Clerics are obliged to observe perfect and perpetual continence for the sake of the kingdom of heaven and therefore are bound to celibacy which is a special gift of God by which sacred ministers can adhere more easily to Christ with an undivided heart and are able to dedicate themselves more freely to the service of God and humanity.
§2. Clerics are to behave with due prudence towards persons whose company can endanger their obligation to observe continence or give rise to scandal among the faithful.
§3. The diocesan bishop is competent to establish more specific norms concerning this matter and to pass judgment in particular cases concerning the observance of this obligation.
