From the atheist perspective , watching theists debating how many angels can dance on the head of a pin is always entertaining as is the question of whether Francis is a heretic , I leave that to the true believers...but from my perspective  this particular pope is nothing more than a modern day New Leftist ( Communist )  liberation theologian ( as he revealed during his 2016 visit to Mexico) ...he stated that " it is the Communists who think like Christians", and , there is , of course an element of truth in that.

Christian Communism , the radical wing of Christian socialism, exists, Karl Marx was a Christian and was a member of the League of the Just, a Christian- Communist organization.

Modern day Christian Communists share many of the goals of modern day Marxists in particular the replacement of capitalism with socialism, which Francis , I'm certain , would agree with .
