For decades, the central doctrine of the Watchtower Society (a.k.a. Jehovah's Witnesses) was that of the "1914 generation". The Society taught that the generation referred to at Luke 21:32 was in fact the generation of people living during the year 1914, and as such would not "pass away" before "all things" occurred - the battle of Armageddon followed by a reconstituted paradise earth.

As the self-proclaimed "channel of communication" for God,¹ all unique Watchtower doctrine is said to originate from God; and the 1914-generation prophecy is no exception. The fulfillment of "all things" before the generation of 1914 passed away was said to be "the Creator's promise"  and "Jehovah's prophetic word".  Notice:

Most important, this magazine builds confidence in the Creator's promise of a peaceful and secure new world before the generation that saw the events of 1914 passes away. –Awake!, January 1, 1995, page 2.

Jehovah's prophetic word through Christ Jesus is: "This generation [of 1914] will by no means pass away until all things occur." (Luke 21:32) And Jehovah, who is the source of inspired and unfailing prophecy, will bring about the fulfillment...² –The Watchtower, May 15, 1984, page 6-7.^view view

After stretching a generation to the maximum conceivable length and then some, the Society finally cut their loses in 1995 and abandoned what had proved to be yet another embarrassing false prophesy. The term "generation" was redefined and no longer bound to those living in 1914.³

Now if you have been associated with Jehovah's Witnesses and the Watchtower Society for any length of time, you know that changing doctrine is par for the course within the organization. In an attempt to rationalize this, the regular back and forth of Watchtower doctrine is likened by the Society to a ship "tacking in the wind".⁴ (Ephesians 4:14 comes to mind.) However, even if we forgive the Watchtower Society their ever-changing doctrine, it seems to this commentator that proclaiming falsehood in the name of God must have consequences.

And it seems that on this point at least, the Watchtower Society is in agreement. Consider the following admonition given by the Society in the pages of The Watchtower magazine:

We dare not lie against God's Word, adding to it or taking away from it, reading into it what it does not say and denying, passing over or explaining away what it does truthfully say. "Every word of God is tried ... Add thou not unto his words, lest he reprove thee, and thou be found a liar." (Prov. 30:5, 6, AS) We may not tell untruths in his name, for that puts God in the light of a liar. "Let God be found true, though every man be found a liar." (Rom. 3:4, NW) In Jeremiah's day the false prophets prophesied lies in Jehovah's name and lied against his purpose, foretelling in his name what he had not foretold. Therefore Jehovah was against them. He executed judgment against them at Jerusalem's destruction in 607 B.C. (Jer. 23:25; 27:15) Religious liars like them today cannot escape a like judgment but will meet a like end at Armageddon. –The Watchtower, February 1, 1956, page 88.

That the Watchtower Society is guilty of "adding to" God's word, "reading into it what it does not say" cannot be disputed. Notice again how they added their 1914-generation prophecy to God's word:

Jehovah's prophetic word...is: "This generation [of 1914] will by no means pass away until all things occur."⁵ –The Watchtower, May 15, 1984, page 6-7.

There's really no way the Society could be more guilty of adding to God's word, reading into it what it does not say. This is precisely what they did. Since the Watchtower Society itself now admits their 1914-generation doctrine to be false, they are also demonstrably guilty of 'telling untruths in God's name', and "foretelling in his name what he had not foretold." Notice again how they said their admittedly false prophecy was "the Creator's promise":

...this magazine builds confidence in the Creator's promise of a peaceful and secure new world before the generation that saw the events of 1914 passes away. –Awake!, January 1, 1995, page 2.

There is no need for this writer to condemn the Watchtower organization; they themselves have done so: just as Jehovah executed judgement against those who foretold in His name what He had not foretold during Jeremiah's day, "religious liars like them today cannot escape a like judgment but will meet a like end at Armageddon."
