Man! If all churches had the guts to do this, we would see a higher standard in christian communities/churches. A purge Sunday says, "We are serious about being Christ-followers. Are You?"
Since Cavey arrived in 1996, "purge Sundays" have been held once or twice a year, devoting the teaching time to challenging people to turn from being church "consumers" to being "contributors." A typical purge sermon (or mini-series of two to three sermons) walks listeners through the biblical basis of what normative Christian life in community should look like.
Then people are asked to make a choice -- to get fully committed to being integrated into normal church life -- or to find another church where they'll be able to do that.
.... "We encourage them not to come back to The Meeting House if they're going to continue to be a passive observer," says Cavey.
