In 13th century, St Thomas Aquinas developed conditions or rules for a war to be considered just or fair to fight:
Must be a just cause - those attacked must have committed some fault - self defenc, not to acquire wealth or power.
2. War must be declared and controlled by a competent and legal authority.
3. War must be last resort, and only used when all other options have been exhausted.
4. War must e right intentions - to promote cause of good and avoid evil, aiming to restore peace and justice.
5. Must be a reasonable chance of success - good achieved from war, outweighing evil that lead to war.
6. Proportionality only use enough force to achieve your aim and if possible, civilians shouldn’t.t be involved.
Just War = war declared for right and noble reasons and fought in a certain way.
Isn’t war that is good, but war Catholics feel to be necessary or just in circumstances when all other solutions have been tried and failed.
Most Catholics support war if justified by Just War standards.
Many Bible references oppose violent conflict - Jesus urges his followers to avoid and actively try to stop conflict - Jesus says that even anger and hatred are destructive.
Christianity teaches that people should live alongside each other in mutual tolerance (however most accept that war is sometimes inevitable).
