Pagan Religions, 1929, Isis, Osiris, Hermes, Mithra, Gnostics
What religions were there in the first-century world to give men assurances in regard to the future of the soul?
The one group of first-century religions which did specialize in future guaranties were the mystery cults from Greece and the Orient. Originally intended to assure the miracle of healthy, new crops in the springtime, they were perfectly adapted to guarantee the miracle of the spirit after physical death.
These were the basic principles governing religion during that time and they all sprang from the mystery cults from Greece and the far east. Even Christianity.
