1. On God the creator of all things
First dogmatic constitution on the church of Christ
Chapter 1 On the institution of the apostolic primacy in blessed Peter
Chapter 2. On the permanence of the primacy of blessed Peter in the Roman pontiffs
Chapter 3. On the power and character of the primacy of the Roman pontiff
Chapter 4. On the infallible teaching authority of the Roman pontiff
And so in the performance of our supreme pastoral office, we beseech for the love of Jesus Christ and we command, by the authority of him who is also our God and saviour, all faithful Christians, especially those in authority or who have the duty of teaching, that they contribute their zeal and labour to the warding off and elimination of these errors from the church and to the spreading of the light of the pure faith.
But since it is not enough to avoid the contamination of heresy unless those errors are carefully shunned which approach it in greater or less degree, we warn all of their duty to observe the constitutions and decrees in which such wrong opinions, though not expressly mentioned in this document, have been banned and forbidden by this holy see.
