The Protestant movement divides into different groups as the Reformation spreads. How are we to interact with other Christians who may not agree on every theological point? Also discussed is the use of the term "Lutheran", why Luther did not like it (especially at first), and why we use the term today. NOTE: I stated the Lutheran Church-Missouri (LCMS) is part of the Lutheran World Federation. That is not correct, I meant to say we were part of Lutheran World Relief.
