How interesting. It's funny how Jesus supposedly selected an apostate religion (which, by it's own qualification it is).
I have a genuine copy of The Divine Plan of The Ages which I discovered in an old book shop. It's the one with the pyramid diagrams.
I also have the blue Creation book written by Rutherford I believe which is not quite so old.
Both very stupid reading though.
I also have Life Everlasting in Freedom of The Sons of God which very clearly shows the whole 1975 teaching (Franz).
I'm serious, these guys were seriously off their trolly.
Nowadays I wouldn't go near it with a disinfected barge pole.
