Asked what Catholics can learn from Lutherans and what they should value of the Lutheran tradition, Pope Francis responded, “Two words come to my mind: reform and Scripture.”
At a “difficult time for the church,” Martin Luther tried “to remedy a complex situation,” the pope said, but for a variety of reasons, including political pressure, his reform movement triggered the division of the church. But Luther’s intuition was not altogether wrong, the pope said, because the church is called to be “‘semper reformanda’ (always reforming).”
In addition, he said, “Luther took a great step by putting the Word of God into the hands of the people” and giving them the Bible in their language, rather than in Latin.
