"We believe and confess a holy, catholic, and apostolic church, out of which there is no salvation; we also acknowledge its unity, that it is one only body, with one only head, and not with two, like a monster. This only head is Jesus Christ, and St. Peter his vicar, and the successor of St. Peter. Therefore, the Greeks, or others, who say that they are not subject to that successor, must acknowledge that they are not of the flock of Christ, since He himself has said (John, x, 16) 'that there is but one fold and one shepherd.'
"We learn that in this church, and under its power, are two swords, the spiritual and the temporal: of these, one is to be used by the church and by the hand of the pontiff; the other, by the church and by the hand of kings and warriors, in pursuance of the orders or with the permission of the pontiff. Now, one of these swords must be subject to the other, temporal to spiritual power; otherwise, they would not be ordinate, and the apostles say they must be so. (Rom. xiii, 1.) According to the testimony of truth, spiritual power must institute and judge temporal power; and thus is verified with regard to the church, the prophecy of Jeremiah (i. 10): 'I have this day set thee over the nations and over the kingdoms.'"
On the other hand, Philip the Fair assembled the states-general; and the commons, in the petition which they presented to that monarch, said, in so many words: "It is a great abomination for us to hear that this Boniface stoutly interprets like a _Boulgare_ (dropping the _l_ and the _a_) these words of spirituality (Matt., xvi. 19): 'Whatever thou shalt bind on earth, shall be bound in heaven;' if this signified that if a man be put into a temporal prison, God will imprison him in heaven."
Clement V., successor to Boniface VIII., revoked and annulled the odious decision of the bull _Unam Sanctam_, which extends the power of the popes to the temporalities of kings, and condemns as heretics all who do not acknowledge this chimerical power. Boniface's pretension, indeed, ought to be condemned as heresy, according to this maxim of theologians: "Not only is it a sin against the rules of the faith, and a heresy, to deny what the faith teaches us, but also to set up as part of the faith that which is no part of it." (Joan. Maj. m. 3 sent. dist. 37. q. 26.)
