Title XX: Of the Preaching of the Divine Word

§ 1. The office of preaching the Catholic faith has been committed chiefly to the Roman Pontiff for the universal Church, and to Bishops for their dioceses.

§ 2. Bishops are held by the office of preaching the Gospel personally by themselves, unless they are prohibited by a legitimate impediment; and besides pastors, they must also take other suitable men as helpers for salutarily executing the office of preaching of this kind.

It is lawful for no one to exercise the ministry of preaching unless he has received a mission from a legitimate Superior, by a faculty peculiarly given or by an office conferred to which, from the sacred canons, the office of preaching inheres.
