Not all, for a few goofy reasons which I don’t get. In the LCMS district (diocese) leaders are called “presidents” in part because their duties include more than just things rated to the office of bishop. It is still kind of silly.

Indeed. I’ve never really understood why we don’t just refer to our DP’s as bishops.

My own personal opinion is that it’s an unfortunate holdover from early American history. You know, the whole “We’re-trapped-in-America-with-a-bunch-of-Reformed-folks-so-don’t-look-too-Catholic!” thing. Pity, really. I think we miss out on greater chance for ecumenism because other church bodies look at us and, at first glance, dismiss us as some run-of-the-mill protestant church.
Indifferently:
Do you have any articles I can read on the issue?
Article XXVIII of the
Augsburg Confession is a good place to start.
To understand why American Lutheranism (particularly the LC-MS) along with Australian Lutheranism (to some degree, anyway) have embraced a largely congregational polity, it might be helpful to read some history on the Prussian attempt at unionism and the resulting fear of state-appointed bishops among Lutherans. Another good thing to research would be the Altenburg Debates. They’re like a time capsule - the American Lutherans are discussing whether to remain episcopal, or whether it was even essential. I don’t know of any online sources, otherwise I’d link you…
Edit: I meant to stress that American Lutherans have not so much
rejected the traditional episcopacy, as they have
adopted a congregational polity. The Apostolic
teaching is what ultimately matters to Lutherans.
