"It is clear, therefore, that in the supremely wise arrangement of God, sacred Tradition, sacred Scripture and the Magisterium of the Church are so connected and associated that one of them cannot stand without the others. Working together, each in its own way under the action of the one Holy Spirit, they all contribute effectively to the salvation of souls…this Magisterium is not superior to the Word of God, but is its servant. It teaches only what has been handed on to it. At the divine command and with the help of the Holy Spirit, it listens to this devotedly, guards it with dedication and expounds it faithfully."
- Pope Paul VI, Dei Verbum
