Further to theBibleResearcher's comments, C.T. Russell adopted the date 1874 from the Second Adventists - but after the event, and by which time they had modified its significance to beginning the "invisible return" of Jesus Christ. (The meeting between Russell and the Second Adventist's N.H. Barbour occurred sometime in 1876). The Second Adventists were a result of the wreckage of William Miller's Adventist movement. The JWs, however, were only very indirectly so.
However, both Russell and Barbour both believed that 1914 would mark the end of the "last days", and definitely see the end of the world. (Barbour later abandoned this idea, but Russell never did - until 1914 came and went, after which he amended it to 1915, according to his The Time is at Hand of that same year).
Likewise, in the early 1920s, the Witnesses did predict that the end would happen in 1925 (WT 7/15/24, p.211). This was the thrust of J.F. Rutherford's bombasts that "Millions Now Living Will Never Die." (Incidentally, the "understanding" about the Other Sheep came about ten years after that, in 1935).
Once again, the JWs were expicit about expecting the end to happen in 1975. While they may not have anywhere in writing said precisely that "Armegeddon will happen in 1975", that thought was left hanging there repeatedly:
- so as to leave the reader with no doubt that this is what the WTS believed; and furthermore, what it wanted its readers to believe. (Either that, or the WTS made an abysmal job of communicating what they did believe!).
Just a few examples of many include Life Everlasting in Freedom of the Sons of God (1966). Around about page 29, after extensive discussion about 1975 marking the 6000th anniversary of human creation, the expression "appropriate" was used to describe the sequence of events should God pull the pin on "This System" during that same year.
Further to that, a series of Watchtower articles in 1968 added fuel to the 1975 fire :
- WT 5/1/68 p.271 spoke of the "gap" as being "less than one year."
- WT 8/15/68 p.499 talked of "weeks or months - not years."
During those years, I was an avid reader of everything that the WTS printed, and I saw first hand how their writings about 1975 were interpreted:
- both by Witnesses and non-Witnesses alike.
In addition to what was written, much more was said from the platform - much of it quite specific that the end would be in 1975.
So what Mankelli says concerning JW predictions about the date of "Armgeddon" are quite correct - and it would take a great excercise in weasel talk to try and talk their way out of that one (particularly the 1975 date). Not to say it hasn't been tried, however!
