“Unam Sanctam,” papal bull of Pope Boniface VIII (papacy 1294–1303 CE), asserts papal supremacy over every human being. Historians consider this one of the most extreme official statements of papal spiritual and temporal supremacy ever made.
Leaving no stone unturned, the papal bull ends –
“Furthermore, we declare, we proclaim, we define that it is absolutely necessary for salvation that every human creature be subject to the Roman Pontiff.”
Today, Boniface is probably best remembered for his feuds with (the poet–writer) Dante, who placed him in a circle of Hell in his Divine Comedia.
