The Following Passage Is from the Papal Bull Unam Sanctam

The following passage is from the papal bull Unam Sanctam (Evaluating the Evidence 9.2) , issued by Pope Boniface VIII in 1302: "And we learn from the words of the Gospel that in this Church and in her power are two swords, the spiritual and the temporal. . . . Truly he who denies that the temporal sword is in the power of Peter, misunderstands the words of the Lord, 'Put up thy sword into the sheath.' Both are in the power of the Church, the spiritual sword and the material. But the latter is to be used for the Church, the former by her; the former by the priest, the latter by kings and captains but at the will and by the permission of the priest. The one sword, then, should be under the other, and temporal authority subject to spiritual. . . ."

A) The church has authority over spiritual, not secular, matters.
B) Kings are superior to popes in some, but not all, matters.
C) The church is the supreme authority in Christendom.
