The foundation of Conservatism is Christianity. It cannot exist as a philosophy of governance without it.
I disagree, but can offer no evidence. I’ve long felt that morality doesn’t require religious belief, still, I was raised catholic and was an altar boy back when the Mass was in Latin. (Now a card carrying agnostic)
The foundation of modern Conservatism is John Locke. From there: Voltaire, Rousseau, David Hume, and Immanuel Kant.
That group was made of Christians, Deists, and agnostics. Some, like Kant and Voltaire believed that reason trumped religion, and wrote that there is a practical necessity to believe on God.
Others believed in Christ’s gospel but were very disillusioned with organized religion. The reason Christianity flourishes in the classical liberalism beliefs is because they believed each person had the right to determine that aspect for themselves.
They were hostile towards organized religion, but not towards people believing in it.
Also, can a country be conservative if it is Jewish?
Russell Kirk, one of the greatest proponents of conservatism, created this list of principles upon which he believed conservatism was based:
1. A belief in a transcendent order, which Kirk described variously as based in tradition, divine revelation, or natural law;
2. An affection for the "variety and mystery" of human existence;
3. A conviction that society requires orders and classes that emphasize "natural" distinctions;
4. A belief that property and freedom are closely linked;
5. A faith in custom, convention, and prescription, and
6. A recognition that innovation must be tied to existing traditions and customs, which entails a respect for the political value of prudence.
I believe that believing and faithful Jews, Hindus, and even some Muslims are capable of following the above set of principles.
With your beliefs I trust you were against the recent wars in Iraq and Afghanistan. After all, if success would only have occurred with the conversion of all Iraqis and Afghanis to Christianity, then that would have been an impossible result to imagine thus making both wars unjustifiable.
