Childish prank. . . BUT . . . . . .
As a kind of thought experiment. . . .
Yeah, imagine if you just picked out a bunch of congregations close together, a circuit's worth. Send out a letter with the official letterhead with content along the lines of "As of August 1, Saturdays are now considered Family Recreation Day, whereby all families will arrange for wholesome activities such as: going to the beach; seeing an exhibit at a museum; participating in sports/physical activities. With warm Christian love, Your Brothers. . . . "
I could just imagine the reaction!
Even after they learned it to be false, you would never get another publisher out in field circus on a saturday ever again!
