I'd like to hear about that from a person who has had actual first hand experience with the movement.
Well, I was/am a Rastafarian, but I never worshipped Haile Selassie. Dr. Vernon Carrington (Prophet Gad) was the first Rasta to explain that Haile Selassie was not God, and that true Rastas who follow His Majesty's teachings must worship the God that Haile Selassie worshipped- Jesus Christ. Dr. Carrington founded the "12 Tribes Rastafari" mansion, which is now the largest body of Rastafarians in the world (Rastas often quote Our Lord's words, "In My Father's house there are many mansions.") 12 Tribes Rastas worship Jesus Christ, although many view Haile Selassie as an icon of Christ.
So, it is not true that ALL Rastas worship Haile Selassie. But those who do worship Haile Selassie (most notably the Rastas of the Nyahbinghi mansion) are very adamant about their belief and often intolerant of those who dare to question it. Believe me, I have had many discussions/debates/reasonings with Rastas of this persuasion. They tell me I cannot be Rasta if I do not worship His Majesty. I ask them how they can call themselves Rasta when they practice a religion different than that of Haile Selassie. These discussions usually don't progress much further than this.
OK, hope that helps clarify it a little bit.
Some of you may be wondering if I still consider myself a Rasta? It's a delicate question. Rastafari led me to Christ, and to the Orthodox Faith. So, how can I ever reject Rastafari? Yet, after I was baptized, my Priest told me that I didn't need to call myself a Rasta anymore. It was interesting that he said I didn't need
to do so, not that I must not do so. Anyway, I identify myself first and foremost as an Orthodox Christian. But I do not hesitate to identify myself as a Rastaman when I am around other Rastas. But I am clear in expressing my Orthodox Faith, and one of my missionary endeavors is to see more Rastas repent from the idolatry of Selassie worship and come to Our Lord through the Orthodox Church.
Pray for me, and for our Rastafarian brothers and sister.
