For some 35 years prior to 1914, The Watchtower (now the most widely distributed religious magazine on earth) had been calling attention to 1914 as a year marked in Bible prophecy. These prophecies began to have a remarkable fulfillment in 1914. One of these was Jesus' own prophecy, uttered 1,900 years ago, concerning "the sign" that would appear at the end of the system of things and that would prove that he was invisibly present with kingly power. In answer to his disciples' question about this "sign," he said: "Nation will rise against nation and kingdom against kingdom, and there will be food shortages and earthquakes in one place after another. All these things are a beginning of pangs of distress." (Matthew 24:3, 7, 8) In striking fulfillment, the first of the world wars started in 1914....
This is a from of dissemblance known as "Implication through ambiguity." This happens when statements which the target audience regards as true are strung together in a manner that conveys a false impression. What happens is that the frame of reference suddenly shifts in a manner that the audience will not grasp. This has been a favorite technique of politicians for time out of mind.
Let's take the statements one at a time:
A: "For some 35 years prior to 1914, The Watchtower.....had been calling attention to 1914 as a year marked in Bible prophecy."
--True:
(From this point on, the frame of reference shifts from what the Bible Students believed and taught prior to 1914, to what present day Witnesses believe and teach. However since the target audience is ignorant of many of these differences, they fail to grasp the misdirection and come away with the mistaken idea that the events which transpired in 1914 were predicted beforehand.)
B: "These prophecies began to have a remarkable fulfillment in 1914."
--Ambiguous in this context: True only from the standpoint of Jehovah's Witnesses today. False from the standpoint of Bible Students prior to 1914 who believed they began to have a remarkable fullfillment in the late 1800's.
C: "One of these was Jesus' own prophecy, uttered 1,900 years ago, concerning "the sign" that would appear at the end of the system of things and that would prove that he was invisibly present with kingly power."
--Ambiguous in this context: Prior to about 1930 it was taught that the end of the system of things commenced in 1799, that the parousia commenced in 1874 and that Christ received kingly power in 1878. Not one of these were regarded as true about 1914 in the 35 years prior to that date.
D: "In answer to his disciples' question about this "sign," he said: "Nation will rise against nation and kingdom against kingdom, and there will be food shortages and earthquakes in one place after another. All these things are a beginning of pangs of distress"
--Ambiguous in this context: In the 35 years prior to 1914 it was thought that these things were already under way. The dawn of the millennium in the fall of 1914 was in fact, supposed to put an end to them.
E: In striking fulfillment, the first of the world wars started in 1914....
--Ambiguous in this context. The "Striking Fulfillment" is not a fullfilment of what was preached during the 35 years prior to 1914. It is only a retrospective fulfillment of the end-time prophecies as understood by Jehovah's Witnesses today. None of the prophecies taught during that 35 year period prior to 1914 save the idea that it marked the expiry of the Gentile times are regarded by Jehovah's Witnesses today as true.
Statements B through E are therefore irrelevant to statement A.
