According to the all mighty teachings of Indiana Jones the first letter in Jehovah is actually "I" so that would make the religion wrong if they can't spell the got damn name right.

Only in latin.

The first name given to God was in latin, and has since then been translated, as was the entire Bible. So the names, and everythign have been re-interpreted. Jehova is the translated name. It is also worth noting that the translators likely could have made mistakes in translating the scriptures, so the Bible as it is known is more than likely in accurate in some areas. The obvious one being, that from language to another, there are often many words which have no equivalent in another language. There are languages in Africa that have no concept of color in their language, and it is literally impossible to speak of color in the language or decribe it.
