Actually, the apparent "new light" in this case, that the FDS is the Governing Body, makes more sense, to me anyway. Here's why:
Years ago, we had an old sister around who was a partaker and thus supposedly part of the "Slave". But here was an old lady who contributed nothing to the feeding of the "domestics". Most of the anointed, in fact, do little to "feed" anyone spirtually.
So from their standpoint, it makes more sense that a group directly involved in the publication and dispensation of such 'spirtual food' would be those who actually had a part in it rather than some old woman or man who partook but did little else.
