The LCMS Reporter website posted an article (no longer available) earlier today on the newly released LCMS Worship Practice & Attitudes Survey (no longer available). The survey compares the responses of the Top 5% congregations (highest percentage and number of adult confirmations in 2006) and a random sampling of congregations on their worship practices and attitudes.
And the survey says . . . . nothing earth shattering. I read through the 42 page survey results, yawned, and moved on. A brief summary is:
For the most part, there are few statistically significant differences in worship practices between the two samples, and those differences are primarily related to elements of the different styles [of worship - my addition].
