Church is the Most Important Institution?

As I was finishing up scanning folder #139. "The Sabbath: An Isle of Safety," I found this little blurb in the church bulletin for services at Pacific Methodist Church in Pacific, MO, for July 22, 1951:

"Some Sabbath Barbs," indeed. It is peculiar for me—a 21st century, 20-something Christian—to see such blatant pro-church propaganda. Did my great-grandfather's generation really believe that the "Churches are the most important institutions in any community"? The postmodern (and indeed, post-Christian) movement have defied such a notion quite heartily. So much so, in fact, that I think it would be difficult to find a Christian under the age of 30 that would agree with the "Sabbath Barbs" above. If you are a Christian (regardless of age), do you believe that the Church is the "most important institution" in a community, or are there others that serve equal or higher purpose?
