At opposite ends of the spectrum of religious responses to conflict are holy war and pacifism. A holy war is a war fought for religious reasons, believed to be sanctioned by God. Pacifism is the belief that all violence and war are wrong. This lesson explores both concepts and their place in Christianity and Islam.
A holy war is a war fought for a religious cause or commanded by God/Allah. It is the most extreme religious justification for violence.
The most significant example of Christian holy war was the Crusades (1095-1291):
| Feature | Explanation |
|---|---|
| Commanded by God | Believed to be ordered or sanctioned by God/Allah |
| Religious cause | Fought to defend or promote the faith |
| Spiritual rewards | Participants may be promised spiritual rewards (e.g. forgiveness of sins) |
| Led by religious authority | Often called for by religious leaders |
| No limits on violence | In some cases, extreme violence was justified as God's will |
The Old Testament contains accounts of wars commanded by God:
"The Lord will fight for you; you need only to be still." (Exodus 14:14)
Jihad is sometimes translated as "holy war," but this is misleading:
"There is no compulsion in religion." (Surah Al-Baqarah 2:256)
| Feature | Christian Holy War (Crusades) | Islamic Lesser Jihad |
|---|---|---|
| Purpose | To conquer territory for Christianity | To defend the Muslim community from attack |
| Initiation | Called by the Pope | Authorised by a legitimate Muslim authority |
| Conversion | Sometimes involved forced conversion | "No compulsion in religion" — forced conversion is forbidden |
| Rules | Often had few limits on violence | Strict rules protecting civilians, environment, and prisoners |
| Modern view | Rejected by mainstream Christianity | Conditions so strict that it rarely applies today |

Pacifism is the belief that all violence and war are wrong. Pacifists refuse to fight or participate in war under any circumstances.
Many Christians are pacifists, based on the teachings of Jesus:
"Blessed are the peacemakers" (Matthew 5:9)
"Love your enemies and pray for those who persecute you" (Matthew 5:44)
"Put your sword back in its place, for all who draw the sword will die by the sword" (Matthew 26:52)
| Example | Detail |
|---|---|
| Quakers (Society of Friends) | Committed to non-violence since the 17th century; refused to fight in both World Wars |
| Martin Luther King Jr | Led the American civil rights movement using non-violent resistance, inspired by Jesus' teachings |
| Dietrich Bonhoeffer | A pacifist who ultimately participated in a plot to assassinate Hitler, showing the complexity of the debate |
| Mennonites and Amish | Christian groups that reject all forms of violence |
| For Pacifism | Against Pacifism |
|---|---|
| Jesus taught non-violence and love for enemies | Sometimes violence is necessary to protect the innocent |
| War causes immense suffering and destruction | Pacifism can allow evil to go unchecked (e.g. not opposing Hitler) |
| Non-violent resistance can be powerful (e.g. MLK, Gandhi) | Not everyone agrees that turning the other cheek works in practice |
| "All who draw the sword will die by the sword" | The Bible and Qur'an both contain passages that permit fighting in certain cases |
| War breeds more war — violence begets violence | A government has a duty to defend its citizens |
Exam Tip: Dietrich Bonhoeffer is an excellent case study. He was a pacifist who eventually decided that opposing Hitler was so important that he had to act — even though it contradicted his pacifist beliefs. This shows that ethical decisions are rarely simple.
Holy war and pacifism represent two extreme responses to conflict. While the concept of holy war has been used historically by both Christians (the Crusades) and is sometimes wrongly associated with Islam (jihad), both traditions today overwhelmingly prioritise peace. Pacifism, inspired by Jesus' teaching on non-violence, remains a powerful witness to the belief that all life is sacred and that violence is never the answer — though its critics argue it can leave the innocent unprotected.
