Separation of Church and State

These days people often say the world is going mad!  With all the wars political debates and endless disagreements I often had this idea:  At times like this we need better leaders!  We need some spiritual guidance of what is right and wrong in this world.  We need inspiration.  It cannot be always about money and power!
Coming from science I'd like to bring a simple illustration of the Bell Curve.  This is the universal statistics of how all options spread.

Now let's us talk about intelligence.  The IQ test examines the intelligence of people.  The results are defined such that IQ of 100 is the average.  If you check the bell curve in the graph below, you can see that most people have an IQ between 85 and 115.  The smartest are the 2% on the right side, and the most unintelligent are the 2% on the left.
 

 

In the simplest terms this means that half the people are smarter than the rest.  The other half are not as smart.  So in general the smarter people have a better chance to succeed in life, get a degree, accumulate wealth and so on.  The other half naturally will not have the same chances.  They maybe trash collectors or menial laborers.
For a rational mind it is obvious that the fortunate smarter people have an inherent responsibility to look after the less fortunate ones.  This idea of the greater good is very basic.  We all benefit when others do well. 

All this rational reasoning hardly works in the world of politics today.  Rich powerful people get richer and control politicians.  In the US we have Citizens United which allows corporations to donate unlimited amounts of money to political campaigns.  The oil rich Arab countries keep funding Muslim organizations around the world.  The largest refugee crisis in the world brings a stream of refugees to the shores of Europe every day.  And there is no end in sight.
We believe in the principle of separation of Church and State, so no one expects any religious leader to rise and preach for goodness.  I kept wondering when will such a leader show up?
And then Pope Francis came to visit and gave a speech to congress.  He said what needs to be said: We should respect each other’s traditions.  We should remember the Golden Rule.  Most important: we should protect the sick and the weak.  Homelessness is our communal failure.  We should protect our earth, our common home.  

I wonder how well we can keep this idea of separating religion from politics.  We can all doubt the existence of God (what god?Jesus?  Allah?)  We can all doubt the legends and superstitions attached to the various religions.  But as history unfolds we can see various leaders arise to guide the human connection: Sometimes it is a military commander, sometimes a philosopher or the Dalai Lama.  This time is it a catholic Pope?
