I was reading the Preface last night and shook my head over the ridiculousness of this. How this ever became a religion is beyond me. However, one thing popped out. On pages 3 and 4 of the Preface, it quotes whas Russell said in The Watch Tower, July 1, 1898 p. 203. The part that stuck out was this (highlighting mine):
"(3) The fire from heaven--an epoch of Divine judgements and chastisements upon a maddened but unconverted world, wild in anarchy, as other Scriptures show us. The results of their wars, revolutions and anarchy, in the failure of their schemes, will have a humbling effect, and will prepare mankind for God's revelation of Himself in
"(4) The still small voice. Yes; He who spoke to the winds and the waves of the Sea of Galilee will, in due time, 'speak peace to the peoples.' He will speak with authority, commanding the observance of His long neglected Law of Love. 'And whosoever will not hear that Prophet shall be cut off from among His People.' (Acts 3:32.)"
So, God's revelation of Himself = He who spoke to the winds and the waves of the Sea of Galilee... sure sounds to me like Russell believed Jesus was God.
