Lesson details

Key learning points

  1. Religion may lead to war for reasons including defending its existence, conflict over land, trying to convert others.
  2. Matthew 10: 34-40 suggests that God should come before all others and people should be willing to fight in His name.
  3. The Crusades are an example of Holy War between Christians and Muslims fought over controlling Jerusalem.
  4. Many humanists believe that this type of war is wrong due to the reason behind it and the loss of life.
  5. Christians have a range of views depending on which texts and examples they prioritise.

Keywords

  • Holy War - a war believed to be sanctioned or commanded by God, often fought to defend a faith, secure religious territory, or convert others to a religion

  • Crusades - a series of religious wars fought between Christians and Muslims in the Middle Ages, primarily over control of Jerusalem and other holy sites

  • Symbolic interpretation - understanding a religious text as using symbols or metaphors, rather than taking the words literally

Common misconception

The Crusades were only about religion.

Religion was a big reason for the Crusades, but they were also about gaining land, power, and wealth. Wars often have multiple overlapping causes, not just one simple reason.

Students may take Matthew 10:34–40 literally. Explain that Christians interpret it differently: some see it as symbolic of a commitment to God, others see it as justifying conflict. Stress that interpretations vary and that not all Christians agree.
