This post is from the defunct blog "Dying Church"From Liquid Church:
The local church may support many good and important activities, including mission trips, evangelism, youth ministry, social projects, and so on, but they are all assessed in terms of their effect or otherwise on regular Sunday attendance. People may turn to Christ through the youth mission or Alpha course, and this is good, but they are not banked, they really don't count, until they start to attend Sunday services. I have sometimes felt that the real purpose of the church services is to enable clergy to count the congregation. This is probably a little cynical, but solid church finds its main sense of success in the number of people who attend on a Sunday. Regular church attendance is seen as being a significant test of spiritual health, and church growth is measured in size of congregations. The importance of Sunday attendance and congregational size can never be underestimated for solid church. Believers are one with each other because they are joined to Christ. The temptation is to reverse these priorities, so that by being joined to the church one is joined to Christ.
