Very interesting...
Just to let you know, in the spring of 2014 some higher ups from the LCMS went to the Vatican for a secret meeting with Catholic officials. It was mostly a “get to know us” meeting. What will come out of that is hard to say, but it probably will happen again eventually. Both sides kept it very hush-hush. Who knows what might happen down the road?
From the few things I have heard, it was a introduction and explanation type of thing. This is who we are, and why the other Lutherans hate us.
