1 - how about the Jewish "paradigm"?
2 - I do agree with you that societies with Christian underpinnings do well by human freedom and dignity. But only for the last three hundred years. It took a good sized side order of Enlightenment philosophy added into the mix to activate that "freedom, creativity and fairness".
3 - Your rationale for Christianity is a pragmatic one. "It produces a better society". I can accept that premise and agree with it while still having no personal acceptance of the supernatural in any way.
The Old Testament is the basis of our laws. I don’t mean to exclude Jews when I mention Christianity. They are the basis of our faith and those that follow the Jewish religion follow the same 10 Commandments.
The Christian paradigm—dominated Western Civilization after the fall of Rome and when eradicated by the Postmodern German Philosophy in Europe in the 20th century created the most evil atheist/occultist paradigm in the history of the world.
The reason why the Christian paradigm is the most successful is because it is the most inclusive of religions and believes in free will and teaches people to be responsible for their acts and life. St. Thomas Aquinas (a genius before the Enlightenment) aligned Christianity to Natural Law Theory. John Locke and the USA (and Cicero) have proven that Natural Law Theory is necessary for Just Law and any laws not based on that becomes political law (Positivism) which only gives some groups power over others—unequal law.
Aquinas was quite clear on this also and that is why Christianity is a reasoned, rational religion—more so because of St. Augustine and Aquinas—and has been so successful for cultures. The laws are Just and only in Just societies can their exist real freedom and private property rights.
CS Lewis said it best. Without God we are “trousered apes” and as such, we will act accordingly. The 20th century proved it.
I understand that Christianity has never been “perfect” but that is the fault of man, not the ideology. But judging cultures, it is superior in many aspects....when you consider individual rights and freedom and inclusiveness.
