Because of its long history and breadth of geographical and cultural diversity, this Catholic tradition encompasses many strains and influences of both religious and secular peacemaking and many aspects of Christian pacifism, just war and nonviolence.

[21] There is a long historical tradition that has collected ample evidence to show that the Roman Empire itself was undergoing profound social, economic, and spiritual changes that were only hastened by the invasions.
