It looks like the scientific results are in: The number 1 issue facing the WELS is the Church and Change group. This is the group that recently sent a group of rogue pastors down to the church planting conference in Orlando, FL. At this conference these pastors sat at the feet of Baptist Pastor Ed Stetzer.
It wasn't much later that the C&Cers contracted Stetzer to present at the 2009 fall conference.
I guess we can all recognize why the C&C group is the synod's number 1 issue (according to the readers of BW)
