What are Christian views on war and peace?

4 min read

War and peace are topics that have been at the forefront of ethical discussions within Christian theology for centuries. The Bible, the foundational text for Christians, contains numerous references to both war and peace, often presenting complex scenarios that have been interpreted in various ways by theologians, pastors, and believers. In exploring the Christian views on these subjects, it is essential to consider the scriptural basis, historical context, and the nuanced perspectives that have developed over time.

Biblical Perspectives on War

The Bible does not present a single, unified stance on war. Instead, it offers a range of narratives and commandments that have been interpreted in various ways. In the Old Testament, there are numerous accounts of war, often depicted as instruments of divine justice or judgment. For example, in the book of Joshua, the Israelites, led by Joshua under the command of God, conquer the land of Canaan (Joshua 6:20-21). These wars are often seen as being sanctioned by God, with strict rules and ethics about engagement and treatment of enemies.

However, the Old Testament also contains profound appeals for peace. Psalms and the Prophets, particularly Isaiah, envision a future where peace reigns supreme. Isaiah 2:4 famously states, "He will judge between the nations and will settle disputes for many peoples. They will beat their swords into plowshares and their spears into pruning hooks. Nation will not take up sword against nation, nor will they train for war anymore." This passage reflects a deep yearning for an era of peace and is often cited in Christian pacifist traditions.

In the New Testament, the approach to war and peace shifts significantly with the teachings of Jesus Christ. Jesus’ message emphasizes love, mercy, and forgiveness, extending even to enemies. In the Sermon on the Mount, Jesus tells his followers, "Blessed are the peacemakers, for they will be called children of God" (Matthew 5:9) and instructs them to "love your enemies and pray for those who persecute you" (Matthew 5:44). These teachings have led many Christians to adopt a pacifist stance, opposing war and using non-violent means to resolve conflicts.

The Just War Theory

Despite the pacifist inclinations in Jesus' teachings, the reality of a world plagued by conflict and aggression has led Christian thinkers to develop what is known as the Just War Theory. This doctrine attempts to reconcile the need for maintaining peace and justice with the sometimes necessary act of going to war. St. Augustine, a foundational figure in Christian theology, was one of the first to articulate this theory. He argued that war should be a last resort and must meet certain criteria to be considered just, including a just cause, legitimate authority, right intention, and a reasonable chance of success.

Thomas Aquinas later expanded on Augustine's ideas, adding that the damage inflicted by the aggressor must be lasting, grave, and certain, and that peace must be a central motive even in the midst of war. The Just War Theory has been influential in both religious and secular contexts, shaping international law and ethical discussions about military conflict.

Modern Christian Perspectives

In the modern world, Christians find themselves divided on the issue of war and peace. On one hand, many adhere to a strict pacifist approach, influenced by the non-violent teachings of Jesus and the early church’s stance against military participation. This view is prominent in denominations such as the Quakers, Mennonites, and other Anabaptist groups, who advocate for non-violent methods of conflict resolution and often engage in active peacemaking efforts around the world.

On the other hand, many Christians accept the Just War Theory as a necessary framework in a world where evil and aggression exist. They argue that military force is sometimes required to achieve peace and justice, especially in cases of defending the innocent or liberating the oppressed. This perspective is common in many mainstream Protestant, Catholic, and Orthodox traditions, which also emphasize the importance of rigorous ethical evaluation before, during, and after engagement in war.

The Call for Reconciliation and Healing

Regardless of the stance on war, a central theme in Christian theology is the pursuit of reconciliation and healing. Christians are called to be ambassadors of peace, reflecting the reconciliatory nature of Christ. This involves active participation in peacebuilding initiatives, whether in local communities or international arenas, and striving towards forgiveness and unity even in the aftermath of conflict.

The Christian views on war and peace are diverse and complex, reflecting the broader tensions between the ideals of justice, mercy, and love. Christians are encouraged to wrestle with these issues prayerfully and thoughtfully, seeking guidance from the Holy Scriptures, the teachings of the Church, and the Holy Spirit. In all discussions and actions, the ultimate goal remains the flourishing of all God’s creation in a just and peaceful world.
