Our favorite Jewish physician was amused by the term Orthodox Lutheran. He said with a smile, "Do you eat kosher?" I said, "No, I read kosher."
If you want to separate the sheep from the goats in the Lutheran church, ask the individual what books are being read on a regular basis. Lutherans will say, besides the Bible, Luther, the Book of Concord, Chemnitz.
The Church and Change leaders never read those books. They always read Sweet, Stetzer, and the rest of the Enthusiasts. One WELS pastor gave Barna's The Frog in the Kettle to a member to read. The theme of that book is - how to change the congregation without anyone noticing it, like boiling a frog slowly, step by step.
