The book doesn’t need to be revised as far as the identity of the "faithful and discreet slave" Is concerned. Chapters 6 and 11 help to show in actual practice, the various terms that have been used for "God’s organization" (including "the faithful and discreet slave") refer to "the men who are hidden behind those terms" – the men of the Governing Body. Or as Ray Franz expressed it 30 years ago: ‘\"They and they alone are ‘the organization.’"
Or as the men of the Governing Body have apparently finally figured out: "They, and they alone, are "the faithful and discreet slave."
As far as upgrading the book, we’ll have to wait and see just how the Governing Body tries to bail themselves out of their "old light" into their "new light."
One thing seems certain: As "Captives of a Concept" points out, they are not going to use a DIMMER switch the ‘gradual’ and ‘progressive’ way they interpret Proverbs 4:18. They are going to use a simple ON/OFF switch that turns their "old light" OFF and their "new light" ON.
I’m looking forward to seeing how they do it.
