"Why did God choose a group of white men in New York to run his earthly organization? Oh, and finally one black man...."
Which God did this? I believe that was Rutherford, who had a God complex. It certainly wasn't the Christian God. There was no "group" under Russell.
And regarding the GB being guided by the "spirit", that may be true but they certainly aren't guided by the Holy Spirit. Perhaps they are guided by the "spirit of this wicked system of things." Who knows, not me, but there's nothing authentic about this entire cult.
