"Millions now Living Will Never Die" That teaching persisted for a number of years from the early 1920`s ,sad to say that their would not be anywhere near millions alive today.And with another few years their won`t be anybody alive .
The year 1925 was supposed to see the resurrection of faithful men of old such as Abraham Issac and Jacob and Noah who were to be Princes in the Earth. Of course no such thing happened and we don`t here anything more about that prediction anymore.
The time period between Adams creation and Eves Creation was an excuse why Armageddon was delayed in about October 1975 because they didn`t know how much time had elapsed between the two. That`s all forgotten about now.
Six thousand years of human history was supposed to have ended in about October 1872 according to Studies in The Scriptures Vol.2 1906 , the "Time is At Hand" page 11 (forward 1916 ) puts the start of the One thousand year reign of Jesus Christ as of the year 1873
So in 1906 they the I.B.S.A. as they were then known figured the 6000 years of human history ended in Oct.1872 and the 1000 year reign of Christ began by 1873.
Years later an adjustment was made to pinpoint 1975 as the end of 6000 years of human history by the WTB&TS so presumably the 1000 year reign of Jesus Christ would/should have started in 1976 ?
One might ask did Jesus Christ begin his rule in A.D.33 ? 1914? or 1976 ? or some other time that the JW/GB are going to pull out of their hat ?
The Jehovah`s Witness Governing Body have never ever apologized for misleading any of their members and many of them to their deaths.
Your welcome to add other teachings /beliefs that have faded into oblivion without explanation.
