Quick Summary

The papal bull Unam sanctam, issued in 1302 by Pope Boniface VIII, is a significant document in Roman Catholic history. It asserted the absolute primacy of the pope and the necessity of submitting to the spiritual authority of the church for salvation. The bull declared that there is only one holy Catholic Church, outside of which there is no salvation and no remission of sins. It also stated that within the church, there are two swords, the spiritual and the temporal, but the spiritual sword is to be wielded by the church, and the temporal sword by men, at the church's discretion and by its permission. This assertion of papal authority over secular rulers was a key point of contention during Boniface VIII's papacy, particularly with Philip IV of France.12
