As for them saying THEY never spoke about prophecies in Jehovahs name.....read the below quotes from their own big mouths.
The Watchtower Reprints, July 15, 1894, p. 1677
We see no reason for changing the figures — nor could we change them if we would. They are, we believe, God’s dates, not ours. But bear in mind that the end of 1914 is not the date for the beginning, but for the end of the time of trouble.
Vindication I, 1931 ed., p. 338-339
There was a measure of disappointment on the part of Jehovah’s faithful ones on earth concerning the years 1914, 1918, and 1925, which disappointment lasted for a time. Later the faithful learned that these dates were definitely fixed in the Scriptures
Watchtower 1922 September 1 p.262
The date 1925 is even more distinctly indicated by the Scriptures than 1914. Watchtower 1923 April 1 p.106
Watchtower 1923 April 1 p.106
Our thought is, that 1925 is
definitely settled by the Scriptures. As to Noah, the Christian now has much more upon which to base his faith than Noah had upon which to base his faith in a coming deluge.
