That Giant Sucking Sound.

From the Standing Commission on Domestic Mission and Evangelism:

The most urgent message the Commission has to convey to the Church is not a happy one. The 20/20 movement challenges us to engage God’s mission. One measure of our success would be the doubling of our average Sunday attendance by the year 2020. Current data indicates that we are going in the wrong direction. So far, what has doubled is the rate of decline in attendance.

Here's the whole thing (MSWord document). Thanks to TitusOneNine.
