It sounds like what happens (or doesn’t happen) on Sunday mornings more important to you that you’re letting on. But that’s ok because I personally don’t see a problem with thinking carefully and theologically about what happens at a worship gatherings.

Whether we’ll openly admit it or not, Sunday morning matters a lot to us (as it should).

For instance professional polish. That’s not a mark of being missional in my opinion. It’s simply a matter of contextualization. In some communities professional organization is a way of communicating that this Church is prepared because we really care about what we’re doing. The order of service is tight, the music well produced and the sermon orderly and clear all because that’s the best way to move people to worship and edification. In another context those very same elements things might communicate inauthenticity and fake-ness.

Here’s another example from my church. For some older folks in my church formal dress is one way they express genuine reverence for God. For some younger folks formal dress communicates to them they can’t be themselves, that they have to put on a front. Who’s right? Well they both are. Suits and ties have two different meanings for two different demographics of people. Christian community is best served if both of those groups learn to understand and love one another, not if we pick one groups culture of dress and privilege it over the others.

I think the biggest thing you missed was Jesus and the Gospel as taught according to the Scriptures. A church might have diversity, flat leadership structure etc. but it can’t be missional without Jesus and the Scripture.
