Since you don't oblige me by showing your wisdom, I'll show you a bit of my (still humble) knowledge on the issue.

The separation of the church and faith in Europe has always been a fact. Since the Roman empire, since Emperor Julian who in 362 decreed freedom of religion, passing through Augustine of Hyppo who argued about the mystical world and earthly politics in Civitate Dei, through the London concordat, the chart of liberties, the Magna Carta, the concordat of Worms, al showing the continuous battle between church and state. The Italian wars amongst republics and papacy, the French kings, from Philip the Fair through the Valois and on, who asserted their independence of the church, through Luther, Calvin, Locke and other protestant philosophers who professed this separation and the free arbiter of the individual, until Thomas Jefferson in 1802 in the United States.
You'll find, all over the history signs of this separation, of the individual liberties and free thinking.

Parliaments existed in Europe for 1000 years now, as did universities. I wont even mention the Renaissance and the Enlightenment.
The Christianism itself suffers no comparison with the Islam in terms of treatment of the Individual and dealing with the State.
Despite numerous exceptions and excesses, this is what dominated Europe for 2000 years.


Free at last! Free at last! Thank God Almighty, we are free at last! (Martin Luther King)
