I also noticed several times that the phrase ?raised around the truth? was used instead of ?raised in the truth?. Is this one of their progressive language adjustments, like calling themselves ?Christian Congregation of Jehovah?s Witnesses? instead of ?Watchtower Bible and Tract Society? in official correspondence?
They reference themselves now in letters as the Christian Congregation of Jehovah's Witnesses for legal purposes. In 2000 I believe, when the GB 'officially' stepped down from control of the wtbts, another corporation called the Christian Congregation of Jehovah's Witnesses Inc. was formed to oversee the congregations, elders, DOs, COs etc... So basically they seperated the book publishing corporation from the JWs in the US, mostly for legal purposes. However this is only in the US if I'm not mistaken. Like for example, in Canada, it is still the Watchtower Bible and Tract Society of Canada Inc. that controls the congregations and all of the other stuff.
As for the language change I don't see much to it. It might be that the speaker just made a mistake in his choice of words. I wouldn't read much into it since the expectations from the kids raised as jws are still the same. "Proper Youth" raised in the "truth" are still supposed to get baptized in their early teens, if not sooner, and are expected to pioneer right out of high school, or as soon as they're done a very quick post secondary course to help them make a living.
