Thank you Searcher, that 01 quote is brilliant. It's not quite how I remember the one I'm after, but it's close enough to make no difference.
And while we're on the subject, "Christians do not twist or misrepresent the facts so as to mislead others." (The Watchtower, June 15, 2009, page 17), which is absolutely correct- "CHRISTIANS" do not!
Billy - I did come across that article in my search, and while I agree that not all untruths are lies (unless you regard genuine mistakes as lies), it did not occur to me the time - of course, the WT never lies - it just slips in an "untruth" now and again. So we have "old truth", "new truth", "present truth", and now we have "untruth" - what a brilliant euphasism for a lie.
