Feb 1, 2006 Watchtower, page 25, para 14:
"That issue of The Watch Tower further stated: "in 1920,...Bible Students came to a correct understanding of our Lord's prophecy contained in Matthew 24:14. They then realized that 'this gospel' which was to be preached in all the world for a testimony to the Gentiles or all nations, was not a gospel of a kingdom yet to come but a gospel to the effect that the Messianic King has begun his reign over the earth."
Yes, they teach a 'gospel' that the 'Messianic King' has been reigning over earth (of which Satan is still the God and the ruler) since 1914, yet the 1000 year reign of Christ has YET TO BEGIN!
Nowhere in the bible is 1914 mentioned or even indicated. A little research reveals the chronology and reasoning JW's use to perpetuate this pecular creed is fundamentally flawed.
Clearly, in this respect JW's are teaching a different 'gospel' than what was taught by the apostles and accepted by the disciples. It is a gospel beyond what was taught by the apostles. What does the bible counsel about such types of 'good news' (gospel):
Galatians 1:7-8 "However, even if we or an angel out of heaven were to declare to you as good news something beyond what we declared to you as good news, let him be accursed. As we have said above, I also now say again, Whoever it is that is declaring to you as good news something beyond waht you accepted, let him be accursed."
