Pre 1975 wt put a limit of 6 month on any bible studies. even dear old ladies serving tea to special pioneers for years, were to be dropped after the 6 month ultimatum.
Strange though, with wt expecting the six thousand years to end and paradise to begin,after Armageddon, they never had the guts to actually go into full "judgement message " mode, tracts and all.
Perhaps that is why Armageddon did not come. Wt not printing the right stuff, and UN not responding and attacking... ha ha. Tony came close to the 6 month limit again. nice try.
