This is so sad...
Maybe partly,but mostly no. The main disagreement is about solo scriptura.Solo scriptura, a central part of the Lutheran church, follows Martin Luther's belief that people get to heaven through the faith and grace of God instead of by good works or church favors.
There was once a saying among African-Americans ,"Its a black thing,you wouldn't understand." I believe you're from a Roman Catholic background, so this Protestant thing may seem strange, weird,or doctrinally unsound to you.
Pastor Lindler was also trying to free his congregation from a central bureaucracy he felt was leaving behind traditional Lutheran teachings .He also felt ELCA was becoming a centralized dictatorship. St. Paul's did what they thought was right.
