Pope Boniface VIII promulgated the Papal bull entitled, Unam Sanctam. In it, he speaks of two swords: the spiritual sword (gladius spiritualis) and the temporal sword (gladius temporalis).
We are informed by the texts of the gospels that in this Church and in its power are two swords; namely, the spiritual and the temporal.
In hac ejusque potestate duos esse gladios, spiritualem videlicet et temporalem, Evangelicis dictis instruimur.
Did this Papal bull authorize Christian aggression by the sword (i.e., offensive military action), or does it simply implore Christians to defend themselves against the aggression of others? Or, none of the above?
And, is this Papal bull still in force today?
