When Is War Just? Just War Theory and the Conflict with Iran

In this timely and weighty episode, Pastors Zack and Josh explore just war theory—a historic Christian framework for thinking about when (and how) war can be morally justified in a broken, sinful world. Drawing from Augustine, Thomas Aquinas, Romans 13, and the Sermon on the Mount, they walk through the classic criteria of justice before war, during war, and after war.As the podcast releases roughly 44–45 days into Operation Epic Fury (the U.S. and Israeli campaign against Iran that began February 28, 2026), the conversation applies these principles to real headlines: preventing a nuclear-armed Iran, targeting military capabilities while minimizing civilian harm, the challenges of fighting an apocalyptic ideology, and the high cost of conflict (including U.S. casualties and tragic civilian losses).You’ll hear honest discussion on:The spectrum between pacifism (over-realized eschatology) and “might makes right” imperialismKey just war criteria: just cause, legitimate authority, last resort, right intention, probability of success, proportionality, and discrimination between combatants and civiliansHistorical examples like World War II, the atomic bomb, and the messy realities of the War on TerrorWhy a Christian worldview that affirms humans are made in God’s image fundamentally shapes how we evaluate warThe importance of justice after war—restoration, reconciliation, and pursuing lasting peace (as seen in post-WWII Japan and Germany versus other conflicts)How radical Islamist ideology (explored more in the next episode) complicates traditional just war thinkingThe pastors emphasize that Christians are not warmongers—we should be among the hardest to convince to go to war and the most eager to pray for peace and human flourishing. Yet in a fallen world where evil exists and governments bear the sword (Romans 13), sometimes force is a tragic necessity to protect the innocent and restrain wickedness. True peace is the goal of any just war.Whether you’re wrestling with current events, military service, or how to pray amid global conflict, this episode offers biblical clarity without simplistic answers.
