I have been told the faithful and discreet slaves reside in Brooklyn NY. These men believe they are appointed by God to lead the Jehovah's Witnesses and run a publishing company.
The "faithful and discreet slave", in the beginning years of the Jehovah's Witnesses, was the founder, Russell. When Rutherford took over, the doctrine was changed to include the exclusive anointed, 144,000, of which about 8,000 are claimed to be alive today. Witnesses believe that these "anointed" are destined to rule over mankind, as joint heirs with Christ. An anointed may be male or female.
In practice however, these 8,000 have no direct authority over the society. In practice, an all-male "Governing Body" nearly all who claim to be "anointed", review the publishing proofs and decide what is to be printed.
What scriptures do they use to back up this claim?
Faithful and Discreet Slave:
Matthew 24:45-47 NWT "Who really is the faithful and discreet slave whom his master appointed over his domestics, to give them their food at the proper time? 46 Happy is that slave if his master on arriving finds him doing so. 47 Truly I say to YOU, He will appoint him over all his belongings.
Limited to 144,000:
Revelation 14:1 NWT And I saw, and, look! the Lamb standing upon the Mount Zion, and with him a hundred and forty-four thousand having his name and the name of his Father written on their foreheads.
Excommunication:
The WTS calls it disfellowshipping, or shunning. This is what they say about the matter themselves:

What they don't say is that one of the most serious sins is to question the Faithful and Discreet Slave's authority.
