Rastafari movement members worship former Ethiopian emperor Haile Selassie I as an incarnation of the one true living God, following a syncretism of Judeo-Christian values and African practices. The movement's name comes from the Amharic title Ras ("head")(occasionally rendered as 'duke') and Haile Selassie's given name, Tafari. Rastafarianism is most common in Jamaica.
The movement started in the early part of the 20th century, heavily influenced by the orator and Black nationalist, Marcus Garvey. Initially, the movement was based upon the belief that all people of African descent would eventually return to Ethiopia, and that White civilization was "Babylon" - a metaphor for all evil and wickedness.. Although beliefs vary among members of the movement, a more common focus is the "Africanization of Jamaica". 
Rastafarians meet on a weekly basis for a time of worship and prayers, though they do not have a specific holy day for such services. As Lincoln Thompson sang: "Sunday morning, the heathen running to the temple, during the week they are the devil's disciple."Part of the service often consists of smoking ganja (marijuana) a plant with great spiritual significance to them. They support the legalization of marijuana, citing in their defense several Bible verses:
- "He causeth the grass for the cattle, and herb for the services of man." - Psalm 104:14
- "...eat every herb of the land." - Exodus 10:12
- "Better is a dinner of herb where love is, than a stalled ox and hatred therewith." - Proverbs 15:17
- "They shall not make baldness upon their head." - Leviticus 21:5
