In addition, many teachings in the bible refer to using force and wielding weapons for a just cause. In Luke 22:36, ‘if you don’t have a sword…buy one’. This is referring to the fact that spreading the word of Christianity might be hard as there will be opposition but Jesus defines Christianity as a just cause so if any on the disciple do not have swords, they should go and buy swords and be prepared to fight for a cause. Furthermore, the bible depicts an event where Jesus uses physical force in order to spread the word of God. ‘Jesus entered the temple area and drove out all [the stall merchants]. He overturned the tables … he said …" 'My house will be called a house of prayer’, but you are making it a 'den of robbers.’ People are working (selling) items on Sabbath (Sunday) when it clearly states in the bible that Sabbath should be a day of rest. He uses force to make his point, as it is a righteous cause.
On the other hand, some denominations of Christianity believe that peace is always the right policy to follow. One of these denominations is called the Quakers and they are strong believers in pacifism. This is the belief that peace should always be kept, violence should never be used, and it is always unjustifiable. War is a form of violence, therefore all pacifists are against war, and they believe that it is always wrong.
Furthermore, many people in the world have achieved great things in the world through peace. One example is Irena Sendler who helped evacuate Jews and saved them from the Nazis during the Second World War. She is quoted to have said, ‘you can achieve more by peace than by war’. It is clear that she has achieved a lot through peace and therefore, war is always wrong.
In conclusion, war is always wrong for many reasons. Although many religions set out a set of rules for a just war, they do not define the fuller meaning of a just war. A just war is defined by both belligerents having met the set of criterion. If both sides have made every attempt to resolve the issue peacefully, then it is always possible to resolve peacefully. If war has broken out and one side claim that it is a just war because they have met all of the criteria, then the other side will not have obeyed the rules and hence, war is always wrong.
