There are still some doctrinal disputes. But Pope Francis says that while theologians iron out their differences, the two churches can work together on social issues like caring for the poor, migrants and refugees, and combating persecution of Christians.

Jens-Martin Kruse, pastor of the Lutheran Church in Rome, says Francis' approach has been dubbed "walking ecumenism."

"We are moving together, this is a new experience that we are together on this walk," Kruse adds. "Walking together, we find that we have lots of things more in [common than] we thought before."
