The Watch Tower Society is premised upon a metaphysical foundation unprovable and only disprovable because of predictions.
Had the Society never made claims "urgent" and set out as falsifiable because of attaching actual dates--they would be like every
other religion making supernatural assertions beyond test.
All the doctrines don't matter because they cannot be falsified--except--once again, the Society managed to change them and then
flip back to previous statements. So, once again, they could have gotten off Scot-free, but botched it.
Ultimately, the service done by Ray Franz in Crisis of Conscience is to hold a spotlight up to the utterly numbskull violations of
Metaphysical King's X.
