By Suellen Brewster, Catholic Exchange - For Catholics living in this “piecemeal World War III” learning the Church’s teachings on conflict between nations, especially the basics of Just War Theory, is incumbent upon us. Though our leaders would likely not explain it this way, the international actions being taken currently are in response to “structures of sin” in other nations, so an understanding of this Catholic idea is also helpful... Understanding these two foundational ideas will not make us experts, nor qualify us as advisors to those in authority. But they will help us navigate these turbulent waters as we pray for our military, our leaders, and every human soul involved.
