§1. Bishops, who by divine institution succeed to the place of the Apostles through the Holy Spirit who has been given to them, are constituted pastors in the Church, so that they are teachers of doctrine, priests of sacred worship, and ministers of governance.
§2. Through episcopal consecration itself, bishops receive with the function of sanctifying also the functions of teaching and governing; by their nature, however, these can only be exercised in hierarchical communion with the head and members of the college.
