I hear the word "unionism", not often but every once in a while; for example, Lutherans in the LCMS have their "Renunciation of unionism and syncretism".
I'm just wondering if anyone here has any thoughts regarding how to understand that term? (When I say thoughts, I'm not looking for a dictionary, which I already have. Also, I'm hoping this won't turn into a "Unionism means mixing the goodness and truth or Orthodoxy with the badness and falsity of Roman Catholicism" kind of thread.)
Thanks in advance!
