Along the lines of 1975, one interesting comment was made by the GB. It was to do with teaching something that was incorrect, and an example from 2Tim 1:13 was given (paraphrasing):
"An elder gave a PT and mentioned the 'pattern of healthful words'. He said 'If you take this verse from here, and that verse from there, and then this one, you get a beautiful pattern emerging' and this was like a designers pattern, a pattern on a piece of fabric."
Everyome laughed, as did the GB, since that is not what 'pattern' means in the correct context. This illustrated why the word 'pattern' had to be replaced in the new NWT.
Later in the same talk he admitted "It has to be said, that elder got his idea from somewhere", and explained that something similar once appeared in the WT. This, I've since found, was in w87 11/15 p.21 "The Pattern Established".
Other words replaced in the new NWT include Fornication (Sexual misconduct), and Brazen Conduct now appears in Gal 5 list of works of the flesh.
