It is nice sounding theory that when you separate the Christian Church from the state, you get stability, but it does not pass the common sense test.
For instance, I know it is the first words out of any atheist mouth when you try to talk with them about Jesus, “Explain the Inquisition,” and “Look how evil the church was!” and “Look what they did in the name of Jesus!”
It is true that about 500 years ago, Christian fanatics killed about 10,000 people over a 100 year time period (about 100/year) in the name of the Roman Catholic church. It is a shame on the record of an organization that claims to be promoting the ministry of Christ. Now compare this record to the example of the countries that have officially done away with religion. To the countries that have outright banned religion and imprisoned those who try to practice it (the ultimate test of the theory of separation of church and state).
Yes, I am talking about Communist countries. In the Communist Manifesto, Engel and Marx declared, “Communism abolishes all religion.” In my father’s lifetime, the numbers of people that officially atheist countries have murdered in the name of no-religion is staggering; the USSR slaughtered 20 million, China slaughtered 10 million, Communist Cambodia slaughtered 2 million, Communist North Korea has/continues to murder untold numbers, Communist Cuba has/continues to murder untold numbers, the list goes on.
The grand total is over 50 million dead in the last 80-year time span (over 600,000/year). Even comparing the worst time of “Christian Persecution” to an average time of a just one country that has officially and forcefully separated church and state, the conclusion is obvious: Christianity has a huge calming influence on government.
Your numbers may be too low. Estimates that I have read exceed 100 million.
Don’t compare Christ to some Christians. We are to live like He lived - He’s the example. In other words, don’t look to man but Jesus for Truth - His Truth, His Word. If man was so perfect, so good - we wouldn’t need a Savior. No one can enter into heaven but through the saving grace of Jesus and it’s a gift. God made it simple, man makes it complicated. God’s Word is true and every man a liar.
3000-5000 over a 350 period, as part of an effort to drive the Mohammedans out of Spain, or 10-20 per year. And to be even more precise, the Spanish Inquisition was a particularly Spanish institution. It's not called the Papal Inquisition, because Rome objected to its excesses.
The Myth of the Spanish Inquisition
Finally, the findings of Church tribunals have never been considered to be infallible. Tribunals are simply internal disciplinary bodies. Modern historians, otherwise hostile to the Church, have found that the Spanish Inquisition was relatively benign, in comparison to other comparable institutions of its day.
