Years ago, Francis spoke harshly of the Protestant reformers. But in the run-up to the trip, he has had only words of praise for Luther. He recently called the German theologian a reformer of his time who rightly criticized a church that was "no model to imitate."
"There was corruption in the church, worldliness, attachment to money and power," Francis told reporters this summer.
They are the same abuses Francis has criticized in the 21st-century Catholic Church he now leads.
