Curtis and "founding friend" David French explore Christianity and armed conflict. Viewed through the prism of the Ukraine War, they explore Christian just war theory. David, a former Army lawyer, walks through the moral and theological origins of the law of armed conflict. Curtis emphasizes the differences between the institutional purpose of the state and the church when it comes to war. Applying those principles to the Russian invasion of Ukraine, they discuss the necessity of Ukrainian resistance and the importance of American aid.
