Just War Theory
Just War Theory is a set of rules developed by Christian thinkers (like St. Augustine and Thomas Aquinas) to determine whether a war is morally acceptable to fight. It aims to limit the destructiveness of war.
The Criteria for a Just War
For a war to be considered "just" by Christian standards, it must meet several strict conditions:
- Just Cause: The reason for fighting must be to right a wrong (like defending against an invasion).
- Legitimate Authority: It must be declared by a recognised government, not a private militia or terrorist group.
- Right Intention: The motive must be to achieve good and peace, not greed or revenge.
- Last Resort: All peaceful alternatives (diplomacy, sanctions) must have failed.
- Reasonable Chance of Success: Lives should not be thrown away in a hopeless cause.
- Proportionality: The force used must not be excessive. You shouldn't drop a bomb on a city to kill one person.
- Discrimination: Armed forces must only target enemy combatants. Civilians, hospitals, and schools must be protected.
Religious Views on Just War
- Christianity: Many denominations accept Just War Theory. While peace is the ideal, fighting to protect the innocent from a tyrant can be an act of Christian love (Agape).
- Islam: Islam has a very similar set of strict rules for war (Lesser Jihad). War must be declared by a religious leader, civilians and nature must not be harmed, and it must be for self-defence.
- Judaism: Distinguishes between optional wars (Milchemet Reshut) and obligatory wars of self-defence (Milchemet Mitzvah), which align closely with Just War principles.
- Buddhism: Does not officially accept Just War Theory. Taking life is always negative Karma. However, some Buddhist scholars debate whether using minimal force to stop a mass murderer could be an act of compassion.
Holy War
A Holy War is a war fought on behalf of God, or to defend a religion. It is usually believed that God commands the war and will reward those who fight in it.
Christianity and Holy War
Historically, Christianity engaged in Holy Wars, most famously the Crusades (11th-13th centuries), where Popes called on Christians to reclaim Jerusalem, promising them a place in heaven.
Modern View: Today, the vast majority of Christians completely reject Holy War. They argue that Jesus' teachings ("put away your sword") mean Christianity should never be spread or defended by violence.
Islam and Jihad
In Islam, the concept of Holy War is often misunderstood by the West. The Arabic term is Jihad, which means "struggle."
- Greater Jihad: The most important struggle. It is the internal, daily spiritual battle to be a good Muslim, pray, fast, and avoid temptation.
- Lesser Jihad: The physical struggle or war to defend Islam from threat. This is strictly defensive. It has rules: you cannot force people to convert to Islam ("There is no compulsion in religion" - Qur'an 2:256), and you cannot initiate the attack.
Judaism
In the Torah (the Hebrew Bible), there are accounts of God commanding the Israelites to fight wars to conquer the Promised Land (Canaan). These are historical Holy Wars. However, modern Judaism does not advocate fighting wars to spread the faith today.
Summary: Key Points
- Just War Theory: A Christian framework to ensure war is only fought for the right reasons and in the right way (e.g. proportionality, last resort).
- Islam's rules of war: Very similar to Just War; strictly limits violence to self-defence and protects innocents.
- Holy War: Fought for a religious cause. Historically present in Christianity (Crusades) but rejected by modern Christians.
- Jihad: Means struggle. Greater Jihad (spiritual) is more important than Lesser Jihad (physical defence of the faith).
Frequently Asked Questions
1) Just Cause (e.g. self-defence). 2) Right Intention (aiming for peace/justice). 3) Legitimate Authority (declared by a government). 4) Last Resort (all peaceful methods tried). 5) Reasonable Chance of Success. 6) Proportionality (force used matches the threat). 7) Discrimination (civilians must not be targeted).
Greater Jihad is the internal, personal struggle to be a good Muslim, follow Allah's rules, and overcome evil desires. Lesser Jihad is the external, physical struggle to defend Islam or the Muslim community against an attack (this is the only form that involves war).
The vast majority of modern Christians reject the concept of Holy War. They believe Jesus' teachings of love and peace contradict fighting a war to spread or defend faith. Historical events like the Crusades are generally viewed as a misuse of religion for political gain.
