Apparently, lots of folks.
Start with Morris Chapman, lame duck head of the SBC Executive Committee. Morris has a "white paper" that expresses his "grave concerns" about how the new category of giving, Great Commission Giving, will affect the Cooperative Program, to which he says the Great Commission Resurgence Task Force has given "lip service."
Norman Jameson writes a nice Baptist Press piece about the predictable results of the CP ox being gored. In BP's collection of GCRTF stories are a number of others who decry the new giving designation.
I don't think the CP will be killed off by Great Commission giving. After all, we are about a generation or more into the CP slowly declining. Fact is, churches are making their decisions on this and have for years, and the CP has been receiving less of the offering plate dollars as a result.
Good question. Someone ought to ask and listen to the answers.
