tiff, when he speaks ex cathedra, that is, when in discharge of the office of Pastor and Doctor of all Christians, by virtue of his supreme Apostolic authority, he defines a doctrine regarding faith or morals to be held by the Universal Church, by the Divine assistance promised to him in Blessed Peter, is possessed of that infallibility with which the Divine Redeemer willed that His Church should be endowed for denning doctrine, regarding faith and morals. And that therefore such definitions of the Roman Pontiff are irreformable of themselves, and not from the consent of the Church.'
In this definition there are six points to be noted.
1. First, it defines the meaning of the well-known phrase, loquens ex cathedra; that is, speaking from the Seat, or place, or with the authority of the supreme teacher of all Christians, and binding the assent of the Universal Church.
2. Secondly, the subject-matter of his infallible teaching, namely, the doctrine of faith and morals.
3. Thirdly, the efficient cause of infallibility, that is, the divine assistance promised to Peter, and in Peter to his successors.
4. Fourthly, the act to which this divine assistance is attached, namely, the defining of doctrines of faith and morals.
5. Fifthly, the extension of this infallible authority to the limits of the doctrinal office of the Church.
6. Lastly, the dogmatic value of the definitions ex cathedra, namely, that they are in themselves irreformable, because in themselves infallible, and not because the Church, or any part or member of the Church, should assent to them.
