The suburbs are essentially an attempt to create an alternate Kingdom. A place of peace and security here on earth. As such, it is a noble endeavor, but it does it through exclusion and not through the power of God’s grace and truth.
It strikes me that this critique from a conservative Protestant may not be that different from the standard critique of suburbs since at least the early 1920s. This standard critique goes something like this: suburbia tries to make everything look pleasant – from being able to purchase a home, keeping the lawn neat and green, and having a wholesome life centered around your family – but underneath this surface are human beings striving to break free from conformity, dullness, and consumerism. Conservative Christians who critique the suburbs make a similar case that the comfortable suburban life dulls people’s senses to their need for spiritual renewal. Of course, the two groups have very different outcomes in mind: the first critique often hopes for a return to diverse and exciting cities while the conservative Christians place less emphasis on where one lives in the end and care more about their spiritual state wherever they may be.
