Proposal: How to Link Doctrine (Substance) and Practice (Style)

How to show doctrinal differences among those congregations that have different practices, thus linking doctrine and practice or style and substance?

Would a person off the street attending worship at any number of Lutheran congregations (LCMS) agree that all the churches were of the same denomination?

What would happen if a series of videos of live congregational worship services taken from various denominations in such a manner that the audience would then catagorize the videos according to the doctrines taught or demonstrated in the videos and classified according to the denomination most likely being shown. I would propose that, rather than there be unity among our Missouri Synod congregations, what would present itself would be not only a practical (practicing) difference, but also a doctrinal difference. I would propose that, those congregations of the Lutheran Church Missouri Synod which practice other than Lutheran Divine Service would be seen to be of a denomination not Lutheran, i.e., evangelical, reformed, Baptist, and the like. Perhaps it may even be seen that some practices might be seen as being Anglican, Orthodox or even Roman as well. This in turn might serve well to help congregations not only connect doctrine and practice, but also help them connect to a denomination which is more in tune not only with their practice, but also with their doctrine.
