The heart and soul of doublespeak is euphemistic references. I think many JWs are not aware of how often they do this. Since leaving slightly over a year ago, I have discovered many that I had not even been aware that I used. Now's your chance: List 'em.
Faithful and Discreet Slave (or Slave): Euphemistic reference to Governing Body, the organization, the writers of the Watchtower articles or books, or organizational authority. In the dogma, the term actually refers to the remnant of the 144,000 on earth at any time. This group does not constitute the body that serves in any of the euphemistic roles.
The congregation: Euphemistic reference to the elders or to congregational authority. This euphemistic reference is directly supported in the dogma, however the word congregation actually refers collectively to the body of congregants as individuals.
Add some, I know there are many.
