*Maybe that have restated it. If any can find a reference, please post it. The latest Watchtower Library installed on my computer is from 2001.
Could they change their mind on this topic even if they wanted to? After all it's the Bible that says "For all the wild animals and for all the birds I have provided grass and leafy plants for food."— Today’s English Version, Genesis 1:30.
To acknowledge that animals have been meat eaters all along, and that they will continue to be even in the 'paradise earth' would be to say that they Bible is wrong.
I don't think they would be willing to go there.
I guess they could really reach and say it was 'symbolic,' . But, as already mentioned by others, it's more likely that they just won't mention it any more.
