EIGHT DATES FOR WHEN THE ANOINTED WERE 'FINALLY SEALED'?
Russell originally set the date for the final sealing of the 144,000 as being 1878.
This was subsequently moved to 1881, 1910, 1914, then 1925.
Then in the Watchtower 1933 Nov 15 it was shown that the parable of Matthew 20:1-16 related to the 12 years from 1919 and hence the close of the sealing was changed to 1931.
In 1969 this was changed again to coincide with the introduction of the Great Crowd doctrine in 1935:
w69 12/15 p. 756 par. 9 “Make Disciples”—Till When?
"It is likewise evident that the vision of the “great crowd” (Rev. 7:9) was given to John the apostle after he had the vision of the 144,000 sealed spiritual Israelites. Hence this vision would apply now, specifically since 1935, when the sealing of the 144,000 spiritual Israelites appears coming to its close."
Exactly what 'evidence' is that? Apparently none, as admitted in 2007.
"Thus it appears that we cannot set a specific date for when the calling of Christians to the heavenly hope ends." Watchtower 2007 May 1 p.31
Note: There are a number of likely contributors to this latest admission. By the year 2005, 1935 was 70 years prior and an irrelevant embarrassment. Even the Governing Body contained few born prior to 1935. (Since 2012, all GB members were born after the 1935 'final sealing'). Furthermore, from around 1980 the number of memorial partakers was no longer declining but stable at around 8,500 people, later rising each year from year 2000 until there were over 12,500 partakers in 2012.
