Well, my book has come. It is an amazing book published in 1969. It is 227 pages long in telling of the life of a SDA physician who devoted his life to working for religious liberty for all. This included Cardinal Pacelli and Pope Pius XII, who were the same person.
The book does not tell us anything as to his belief on the State of the Dead. It mentions his coming to Andrews University in June of 1966. I was a student there at that time and I heard him speak and he was questioned about his understanding of death.
He is mentioned meany times on the Internet. I shall post a site below that will inform more about him.
