"For there are two, O emperor Augustus, by which the world is principally ruled: the sacred authority of pontiffs and the royal power." Pope St. Gelasius I reigned as pope from 492 to 496 AD and is best known for articulating the doctrine of "the two swords." This doctrine explains that man is subject to two powers: the temporal and the spiritual. Whereas the temporal power wields natural authority to promote the common good, the spiritual power wields supernatural authority for the care of souls. While recognizing that these two powers complement one another, Gelasius asserts the ultimate primacy of the spiritual authority over the temporal. Pope Gelasius' contributions helped shape the relationship between church and state in medieval Europe, and to this day the Church's position remains what he first described in this famous letter to the Byzantine Emperor Anastasius I.
