As an outsider, you have the same problem that the Catholics do. I shouldn't have to research the church I'm about to visit to see how reverent your liturgy is. The "traditional" and "confessional" Lutheran churches near me have altar girls, a versus populum confection, crosses and not crucifixes, "and also with you", etc. Your worship space and aesthetic is about as bland and stale as a Novus Ordo mass.

There seems to be no sense of reverence or sacredness. The churches are sterile and austere. If someone didn't tell you it was a Lutheran church, you couldn't tell the difference between a Lutheran church, a Presbyterian church, or a Methodist church.

Your faith is very elegant on paper, but in practice, it's a free-for-all. There is no way to enforce orthodoxy, apart from maybe peer pressure because every congregation is an entity unto itself. "You aren't keeping to the confessions." "Yep. We don't care."

I can go to any Orthodox church and almost every time I'll know 99.9% of what to expect. Lutherans? You might get this:
