I would not have believed it if I hadn't seen it with my own eyes. A major Watchtower blunder, one within the last 3 years or so. I can't pin it down, but it doesn't really matter when.
I discovered it after I downloaded from JW dot org the latest WT Lib 2017 file. It's an ISO file and on Windows 10 it's an easy matter to install it.
When I compared certain quotations on this essay I was blown away by position 10 (refer to essay). There, WT nullified position 9 in which they finally had joined mainstream Christianity and where they conceded that "rather than be dogmatic", they would wait on Jehovah.
The blunder? In this download of the ISO several days ago, it became clear that they had back-edited Insight on the Scriptures, a 1988 hard bound research book. There, you will see what they did in position 10. There, once again, Sodomites will not get a resurrection.
We have no way of knowing but I believe it's simply a case of the right hand not knowing what the left hand is doing. A simple blunder.
By the way, the original link on page 1 of this post should still work. What follows is a snippet of a part of page 2.
