Before WELS' COP emasculated WLC's Charis, a Charis research study announced the discovery of a few large, growing WELS congregations. The study did not name those congregations publicly. Perhaps anonymity was supposed to preserve their virgin condition. Charis hoped for follow-on study of the pastors involved. The new, reconstituted Charis may loath opening old wounds, so we may never know their names or stories.
The problem with the old Charis was they used WELS' Statistical Reports to arrive at unpopular conclusions. When Charis analyzed all 1000+ WELS congregations and concluded that LES and ECE programs stunted congregation growth, Charis had to go.
Synods are job programs, and the mission of the COP is to make sure that every MLC grad who wants to work has employment for life. WELS rationalizes overspending on schools (schools are jobs) by insisting that schools are outreach. Charis challenged that pillar of faith.
