Christians are supposed to love their brother as thyself ,so we want to be a blessing to others, and help them, and not cause or create discord. If everyone would care about others as they do themselves it would be a very loving peaceful world. God bless:)
Lets see... What has Christianity contributed to? Multiple religious wars, the crusades, the inquisition, the burning of witches, slavery, anti-Semitism, the Holocaust, the bombing of abortion clinics, the murder and attempted murder of doctors, slander... Wait... What was the question again?
Christianity along with other sects destroyed world peace . There will be no peace on earth as long as there are religions and religious leaders and doctors too . To many people want the role to the part they could never play . There is not only one but one in many .
Christianity does not bring peace to the world as man defines it ,it brings the peace of God/jesus to the follower/believers. Even Jesus brought disruption to the world,caused mans belief to be shaken to it's foundations in what they thought was the way god was suppose to be and who he is. If anything christianity makes people that do not want to hear the word or accept god very agitated/angry/ready to argue/fight because they can't or won't accept what jesus came to the world for(to give his life for our sins).even in china today they have to hide in their homes /meeting places to learn of jesus and worship.so to say christianity contributes to world peace is not quite the right way to define what believing in jesus does.even the bible tells us man will reject jesus when he comes back and puts his feet on the temple mount. Even when they see him and there is no way he could not be anyone else except who he says he is they will still rage against him. Even the believers of islam(the ones that can not handle the truth of jesus)want to destroy the christians because if we are right in believing in jesus then that would mean what they believe is wrong.so to say christianity is here to bring world peace is not exactly the right word/meaning. This is not to say we do not want world peace but to say we can not bend to the beliefs of others to obtain it. You can not serve 2 masters. So again the word "peace" as man wants to use it is not the same as the peace of Jesus. I hope you understand what I am trying to explain.
