Unam sanctam (1302) 
- Unam sanctam ecclesiam catholicam et ipsam apostolicam urgente fide credere cogimur et tenere, nosque hanc frmiter credimus et simpliciter confitemur, extra quam nec salus est, nec remissio peccatorum,
- Translation: WE ARE COMPELLED, OUR FAITH URGING us, to believe and to hold—and we do firmly believe and simply confess—that there is one holy Catholic and Apostolic Church, outside of which there is neither salvation nor remission of sins
- Sive ergo Graeci sive alii se dicant Petro ejusque successoribus non esse commissos: fateantur necesse est, se de ovibus Christi non esse, dicente Domino in Joanne, unum ovile et unicum esse pastorem.
- If, then, the Greeks or others say that they were not committed to the care of Peter and his successors, they necessarily confess that they are not of the sheep of Christ; for the Lord says, in John, that there is one fold, one shepherd, and one only.
- In hac ejusque potestate duos esse gladios, spiritualem videlicet et temporalem, evangelicis dictis instruimur. […] Uterque ergo est in potestate ecclesiae, spiritualis scilicet gladius et materialis. Sed is quidem pro ecclesia, ille vero ab ecclesia exercendus, ille sacerdotis, is manu regum et militum, sed ad nutum et patientiam sacerdotis.
- We are told by the word of the Gospel that in this His fold there are two swords—a spiritual, namely, and a temporal. […] Both swords, the spiritual and the material, therefore, are in the power of the Church; the one, indeed, to be wielded for the Church, the other by the Church; the one by the hand of the priest, the other by the hand of kings and knights, but at the will and sufferance of the priest.
- Porro subesse Romano Pontifici omni humanae creaturae declaramus dicimus, definimus et pronunciamus omnino esse de necessitate salutis.
- Indeed we declare, say, pronounce, and define that it is altogether necessary to salvation for every human creature to be subject to the Roman Pontiff.
