The Rastas seem to be a neo;Gnostic ofshoot, just as the LDS are a pseudoChristian neo-Gnostic offshoot from mainstream doctrine.
This could lead to off-topic stuff. The distinguished American critic Harold Bloom also thinks the LDS are a kind of modern Gnostic group. I'd say this is only true if you're thinking of "Gnostic" in etymological terms - "one who
knows" (rather than has faith -
pistis).
However, LDS are very distinct from the Christian Gnostics of history in that they totally embrace the physical world as good (indeed they think that God and Jesus still have physical bodies), whereas the ancient Gnostics mostly regarded the material world as totally evil.
Don't know about the Rastas attitude to the material world - given their predilection to get out of their heads on dope, it doesn't suggest that they hold the physical world in too high a regard.
