"If it be true that man has an immortal soul that cannot die, it follows
(1) that he who assured our first parents in Eden that they should not surely die (Gen.3:4,5), told the truth, and a belief of the truth was the deception which brought sin into the world to destroy the peace and happiness of mankind;
(2) that the deification of dead men and the worship of ancestors, which prevail throughout heathendom, and upon which so much of idolatry is founded, has at least some foundation;
(3) that the saint-worship, Mariolatry, purgatory, and mass, of the the Roman Catholic and Greek churches, are true doctrines;
(4) that the future coming of Christ, and a future general Judgment, and a resurrection of the dead, can all be set aside as unnecessary;
(5) that Restorationism, Universalism, and Spiritualism can be, on this hypothesis, defended from the Scriptures.
--- On the other hand, if man possesses no such undying principle by nature, as an immortal soul; if the dead are not conscious; if future eternal life depends on Christ alone, all the doctrines and practices named above, topple over as gigantic frauds, deceptions, and superstitions."
Uriah Smith
