I believe that in 1876 Russell published an article showing that the gentile times ended in 1914 and I think that this is still believed by Jehovah’s Witnesses.
I understand that the anointed were commissioned in 1919 to speak in God’s name and in 1920 they discerned that they should preach the good news of the establishment of God’s Kingdom in 1914 in fulfilment of Matthew 24:14 as shown in the Watchtower article Gospel of the Kingdom July 1st 1920.
In the book, Man’s Salvation Out of World Distress At Hand! (Watch Tower 1975) page 47/48
‘The glorification of Jesus Christ in heaven after his extraordinary sufferings as a man on earth was good news, Gospel, Evangel. “Nevertheless,” writes the apostle Paul with special reference to his own people, “they did not all obey the good news…’
…The good news about the Messianic kingdom of Jehovah’s “Servant” is better news today than it was nineteen hundred years ago, in apostolic times. In the face of the relatively small proportion of the world’s population that has put faith in the “thing heard [from] us” or proclaimed by us, it can truthfully be said: “They did not all obey the good news.” ‘
In my opinion I think that if they were to change what
has been proclaimed regarding 1914 it would be the same as changing what has
been preached regarding the resurrection of Christ. So I don’t see it
happening. The teaching of the end of the gentile times in 1914 is for good I
think.
