This is from the 1975 Yearbook, page 146:
The year 1925 came and went. Jesus’ anointed followers were still on earth as a class. The faithful men of old times—Abraham, David and others—had not been resurrected to become princes in the earth. (Ps. 45:16) So, as Anna MacDonald recalls: “1925 was a sad year for many brothers. Some of them were stumbled; their hopes were dashed. They had hoped to see some of the ‘ancient worthies’ [men of old like Abraham] resurrected. Instead of its being considered a ‘probability,’ they read into it that it was a ‘certainty,’ and some prepared for their own loved ones with expectancy of their resurrection. I personally received a letter from the sister who brought me the truth. She advised me that she had done wrong in what she had told me. . . . [But] I was appreciative of my liberation from Babylon. Where else could one go? I had learned to know and love Jehovah.”
1974 came and went, 1914 came and went, 1917 came and went, 1918 came and went, 1920 came and went, 1925 came and went, 1932 came and went, 1935 came and went, 1975 came and went...
...and every time it is said that assigning too much importance to a date was the fault of "some", or "they". But, who are those "some [brothers]" or "they"? Well, to put it in simple terms, all of those "expectations" were made public in printed literature and convention talks. It was not just that some brothers privately talked about it among themselves in their congregations, but rather were published and taught to all. So the only responsible for making people stumble for assigning importance to certain dates were the publishers, and NOT the readers.
