The biggest one that comes to mind is their self proclamation that Christ had returned invisibly to set up his earthly kingdom
around a fraudulent unbibical calculable date of the year 1914.
The people who have studied the WTS. history from its very beginnings know that C T Russel infused the silly and
unfounded belief in Pyramidology to come up with this assertion.
From this dated year they have said over and over again until recently that mankind is living through the end times or
the last days of this system of things.
The supposed sighs of the times to verify this assumption are wrongly proposed based on known facts of human history itself.
It shouldn't be dismissed that this was and always will be a publishing house that is set up to propagate it's literature,
when you mix business with religion usually a tirade of false doctrines appear and this certainly is the case with
this organization.
