When I was a boy I was sure that i was going to have a pet lion in the New World,and was fondly encouraged to believe so by the grown ups and W T literature. As an adult I held reservations, but it has always been official belief that we would be at peace with animals and they will literally all change to a veggie diet.
Recent study of the "Isaiah book page 16 shows a typical picture of wolf,bear etc, and likens it to changed personalities of people.
A literal fulfillment? "It is reasonable to think so......details not known, but confident that everything will be just as it should be"
Somewhat woolley , I believe
Question; Are they shaping to abandon this preposterous literal interpretation of Isaiah's prophecy?
