False. JW have erred in interpreting the year of the great tribulation but not in interpreting prophecy or scriptures relating to the time of the end
Your assertion that the WTS only got the date for the Great Tribulation wrong is false.
What about the date for the first resurrection?
"Why have Jehovah's Witnesses disfellowshipped for apostasy some who still profess belief in God, the Bible, and Jesus Christ? … Do we have Scriptural precedent for taking such a strict position? Indeed we do! Paul wrote about some in his day: "Their word will spread like gangrene. Hymenaeus and Philetus are of that number. These very men have deviated from the truth, saying that the resurrection has already occurred; and they are subverting the faith of some." (2 Timothy 2:17, 18; see also Matthew 18:6.) There is nothing to indicate that these men did not believe in God, in the Bible, in Jesus' sacrifice. Yet, on this one basic point, what they were teaching as to the time of the resurrection, Paul rightly branded them as apostates, with whom faithful Christians would not fellowship." Watchtower 1986 April 1 pp. 30, 31
So, Hymenaeus and Philetus were branded as apostates for teaching a wrong date for the resurrection.
Curiously though, for close to 50 years prior to 1927, the Watch Tower Society, based on certain eschatological calculations, taught that the first resurrection began in 1878.
“In 1878 the process of setting up the kingdom began. The Lord raised the sleeping saints. WT 6/1/1922, p.174”
“Our Lord's resurrection occurred three and a half years after his advent as the Messiah, in A.D. 29; and the resurrection of his body, the Church, we have seen, was due in the year 1878, three and a half years after his second advent, in October 1874." Thy Kingdom Come p. 305
It was only in 1927 that that the date for the first resurrection was changed to 1918
"One of the many enlightening truths that God now gave his witnesses was about the members of God's spiritual nation who had died physically. This was in 1927. In that year the witnesses understood that the dead spiritual Israelites had been raised in 1918 to life in heaven with Christ Jesus. It was an invisible resurrection, of course." From Paradise Lost to Paradise Regained p.192
So WTS leaders classified Hymenaeus and Philetus as apostates for exactly the same error….promoting a false date for the resurrection of the saints which they committed for over 50 years.
To be fair, the only conclusion I can unhypocritically come to is that the Watchtower Organization is apostate along with Hymenaeus and Philetus.
