Very good, except the 'faithful and discreet' slaves, whether are class or not, are indeed 'anointed' in that they would not be faithful slaves whom Jesus approves unless they had received the holy spirit and it was operative on them, either as a class or individually. I think perhaps you mean to word that one differently, because all 'true Christians', of whom the 'faithful and discreet slave' would be one, are of course 'anointed' ie, have been born again.
The real problem is that JW's believe only 144k persons have ever been 'anointed' of the holy spirit.
