“This authority [of the popes] is not human but rather divine, granted to Peter by a divine word and reaffirmed to him and his successors by the One Whom Peter confessed, the Lord saying to Peter himself, ‘Whatsoever you shall bind on earth, shall be bound also in Heaven.’ Therefore whoever resists this power thus ordained by God, resists the ordinance of God. … Furthermore, we declare, we proclaim, we define that it is absolutely necessary for salvation that every human creature be subject to the Roman Pontiff.”
- Pope Boniface VIII, Unam Sanctam (1302)
