The Pope is talking to the wrong Lutherans and visiting the wrong Lutherans in Sweden.  Those Sweden Lutherans are very liberal much like the ELCA in the US -- they are focused on society issues not the Bible.

The ELCA has full Altar and pulpit fellowship with extreme liberal denominations in the US -- some you would question if there really were Christians because they hold no doctrinal beliefs.  RC's should be talking with confessional Lutherans who hold beliefs more like their own.
