Can churches’ self-testimony be trusted?
Brian comments in an earlier post that in a study of megachurches, “18% of the 406 churches claiming that 40% or more were converts, there should be about 70 churches where people are being converted in large numbers.”
I don’t think so.
In the research work referenced earlier, we also often meet with staffers when studying other churches. We routinely ask them what percentage of people they think are converts. Some pastors admit the percentage is low—as low as 18% in one case, but usually 25 to 40%. Yet the survey in those same churches show that only 3 to 7% are actually converts reached at that church. So far, no pastor has come closer to the truth than five times the actual number.
We don’t suggest the pastors are lying. They appear to actually believe that they are doing five to fifteen times better than they actually are. On the other hand, it’s interesting to notice that the same staffs that can break their statistics down in a dozen different ways from memory are unable to give a statistic for the convert vs. transfer composition of their people. They have so far all admitted that they don’t study that question. Perhaps some leaders don’t want to know the answer to this question?
This is Chadwick claim (See William Chadwick, Stealing Sheep: The Church’s Hidden Problems with Transfer Growth, Chadwick thinks church leaders purposely conceal the truth about transfer growth, and that they also purposely seek transfer growth by launching strategies only l
I can’t judge that question, but I do think the blank area in our knowledge here begs for some kind of answer. One thing for sure: You can’t go by what churches say about their own composition! Their statements about their attendance are often correct (not always) but their statements on composition have never even come close.
