Papal Supremacy

  • Doctrine of the Catholic Church which states the pope has power over all matters of the church based on Jesus' delegation to Peter (Matthew 16:18). Pope uses this power politically.

Just War

  • Theory/Tradition that looks at whether wars are justifiable under certain conditions. Augustine sets out four conditions (Proper authority, Defensive or in response to a wrong, must be done out of necessity, must have just intentions).

Holy War

  • Just War applied to the crusades. Reason behind motivation: spiritual, socioreligious, and socioeconomic.
