Giving the man the benefit of the doubt, I would figure that the UC pastor has estimated that the other pastor's shepherding practices are not sufficient to keep the flock together in the long run.
Or I could jump in the air in anticipation of the bandwagon that's sure to come rolling here along any minute now, and say that his words are motivated by fear, jealosy, greed, a desire to control the lives of the "little people," and a lack of confidence in his own message . . . did I cover everything, guys?
