"There was greed and lust for power"

Last June, Pope Francis went so far as to praise Luther — once deemed a heretic by the Catholic Church — as a great reformer.

On his flight back to Rome from Armenia, the pope told reporters: "The church was not a role model, there was corruption, there was worldliness, there was greed, and lust for power. He protested against this. And he was an intelligent man."
