I sort of agree with some of your assertions, but disagree with most. I disagree that it is responsible for modern civilisation. Huge parts of the world were pretty civilised long before christianity.

The first democracies were about 500bc, Slavery was not only endorsed by religion, but actively supported and many religious leaders and sects campaigned against the abolition of slavery. Good people who were religious and a shift in attitudes fought to abolish slavery.

Some art was inspired by religion and much was not. Religions founded many seats of learning and universities, but when their studies contradicted the church they were excommunicated and arrested.
I don't know how you relate the constitution to the bible as it specifically keeps religion and politics separate.
As for top 10 modern countries - China and Japan would contradict this assertion.

I agree that religion has had a significant influence on some modern societies, but that has been a result of how different cults have changed interpretations of the bible to their own ends - if the bible were true, there wouldn't be so many versions of what it means and so many versions of christianity.

@uncorrugated Some good points there indeed. It's such a complicated topic that it would take a small novel to cover all the pros and cons, of course.

Just a couple of comments on your points to consider -

1. Civilization before the New testament.
   "Huge parts were civilised before .." , yes, indeed, but none had the freedom and justice of "modern civilization". Since the rise of Protestants, powered by the published Bible, the advances in civil liberties and scientific and technological advancement have eclipsed all civilisations before that. The Industrial Revolution alone changed the world to an unsurpassed degree, arising from the devout studies of Victorian England.

2. New testament influence on Art. A huge proportion of the great Artistic advancements, perspective, mathematical positioning, the paint medium came about from the power of the Catholic sponsors in Italy, who invariably requested New Testament themes, to curry favour with the Catholic Church. Greeks did pretty well in the sculpture area of course, - based on their own local Gods. Music was profoundly influenced and advanced by the cathedrals and christian churches sponsorship of religious music.

3. New Testament and US Constitution. You are totally right right the Church/State separation - this was after careful decision by the authors, based on history like the problems that Britain had.(the wars between Catholic and Protestant for example) - created by arguments over the New Testament !

But, the principles of the constitution, adhere strongly to the Protestant principles argued out over the previous 100 years. eg. "all men are created equal, that they are endowed by their Creator with certain unalienable Rights", "And for the support of this Declaration, with a firm reliance on the protection of Divine Providence,", "the separate and equal station to which the Laws of Nature and of Nature’s God entitles them " . - are a few of the unashamedly Christian references within the Constitution. Of course, the officers of Government and the Justice system were "sworn with an oath", on the Bible. I think it is safe to say that despite the legal protection of the State from any one religion, the influence of the New Testament can be plainly seen in the overarching outlook of the legal framework,.

4. Top ten Nations - Christianity influence, Bear in mind that Japans prominence owes a lot to its conquering power, the US - its contribution to rebuilding its industries and farming. This would be one of the relatively rare times when a conqueror turned around and established a former enemy as an economic power (Love thy Enemy ?). Bear in mind that China's power is built on the back of the trade with the US (and the industrial espionage) and copying of the US free market principles (equality) after many, many years languishing under various other political systems.

5. " if the bible were true" - I'm sorry that I gave the impression that I thought the Bible was "true". No. I am ONLY noting its role in history, and the benefits to everyone from adopting JC's principles in the MORAL view of history. A lot of people draw attention to how JC's teachings follow Buddhist teachings, and conjecture that he may have been influenced by Eastern philosophy. While there isn't any historical evidence for that, his "revolutionary vision of "love thy enemy" certainly ties in with many eastern philosophies.

The BIG contribution of the New Testament is how it got to be a popular and fairly easy to comprehend set of principles for simple people of the era, and how pervasive the moral principles became to the working class. Without the New Testament influence over the last 2 thousand years, the modern concepts of fairness (kindness) and justice(love thy neighbour) and charity would have found it really hard to creep into the social fabric of the modern world, so I feel that acknowledging its contribution to our quality of life is an important part of understanding history.

We have a lot of problems today that could be solved if only the "devine power" were eliminated.
