NO religion is not rational it is based on faith and NOT on facts. 
That is the reason why religion cannot run a nation. Unfortunately, the RRs (Religious Right - including the American Catholic prelates do not yet understand that fact). 
Let us recall that the Catholic church has been seduced and involved in politics ever since the fourth century. One can easily make the point that Satan seduced the church by offering it earthy powers and the church succumbed to his seductions. 
So now we must question and challenge the church prelates, especially those in America - not Pope Francis because he understands, just how much are they a religion and how much are they simply a Super-Pac for the GOP.  
The other reason why the church is like a fallen thing is that it believes that it works for God while in reality it really only works for itself.
When we the peoples challenge the church we help to keep it on the path of Jesus Christ and OFF the path of godless, soulless, predatory Capitalism.
