Christian's contribution to society.

What have Christians contributed to society? We can begin with education. Most major European universities, Cambridge, Oxford, and Westminster have been founded on Christian principles. In the United States, Harvard, Princeton, Yale, Oxford, Pepperdine, St. Johns, and many others built on Christian thinking.

Other contributions are in hygiene, social reform, medicine, democracy, arts, sciences, and industry, and has had a hand in elevating womanhood. Cannibalism has been abolished, as well as human sacrifice and cruelty by torture because of Christianity. Christians have organized worldwide famine relief programs, as well as local charities. What is now considered current, contemporary values in equality, tolerance, and freedom are all fruits of Christianity as well.

Let me close with this thought. Atheists, Agnostics, gays, pro-choice groups, and Politicians on both sides of the aisle agonize about society and how to transform it. But few there are who give any thought about changing their hearts. The root and branch of Christianity, we change cultures by changing people. Christ and his church have and continue to fulfill their mission. How do we know that to be a fact? Because Christ’s work continues to turn the world upside down.”

Careful with that. There were also a good few prominent slave owners in that group labeled "Christians." And let's not forget the bloody Crusades...

That's only one of the things atheist will come back at you with if you run what you said by them. What will you come back at them with?

I don't think you can denigrate the accomplishments of many with the degeneracy of a few, but they will indeed try.

Looking at the accomplishments of those who truly believe God's word and put their beliefs into action is absolutely impressive. More often than not this came despite opposition and hinderance by both government and "Church". It's the believing people putting their faith in action despite opposition, that made the greatest accomplishments in history. Nothing else comes near.

THE main contribution is the Word of God.

As for other contributions, every race of peoples made contributions in their own way. Sciences, mathematics, even some medicinal practices are a few of the contributions made by non-christian groups.
