8. That heavens doors are open to only 144, 000 people.
9. That the majority of Witnesses must remain on earth.
10. That salvation is found only through the Organization.
11. That salvation can be maintained only by energetic works for the Organization until the end, when one may then merit eternal life on a paradise earth.
12. That Satan is the author of the doctrine of the trinity.
