But the church is an assembly of human beings, and human beings don't experience community without being closer to one another than drive-in services allow. Worship in automobiles is not really social. Christian prudence and the light of nature suggest that drive-in churches aren't good ideas. The drive-in church also lacks any sense of gravity about worship. But of course, we live in a zero-gravity age.
Weightlessness characterizes almost everything about modern culture.
The scriptures do not dictate for us rules defining gravity or reverence, but they are clear that worship should exhibit such a quality. Exactly how we should display reverence and awe is never defined, but it is obviously possible to be irreverent and insouciant, or the writer of Hebrews would never have been so graphic in describing the wrath that awaits the irreverent. Once again, we must consider the light of nature and Christian prudence. Usually through formalized behavior. Talk to someone who understands protocol in international diplomatic gatherings, and you'll find that despite the cultural differences, certain ways of behaving are almost universally ill mannered and presumptuous.
