the NWT is the first intentional systematic effort at producing a complete version of the Bible that is edited and revised for the specific purpose of agreeing with a group's doctrine. The Jehovah’s Witnesses and the Watchtower Society realized that their beliefs contradicted Scripture. So, rather than conforming their beliefs to Scripture, they altered Scripture to agree with their beliefs. The “New World Bible Translation Committee” went through the Bible and changed any Scripture that did not agree with Jehovah’s Witness’ theology. This is clearly demonstrated by the fact that as new editions to the New World Translation were published, additional changes were made to the biblical text. As biblical Christians continued to point out, Scriptures that clearly argue for the deity of Christ (for example), the Watchtower Society would publish a new edition of the New World Translation with those Scriptures changed.
The New World Translation renders the Greek term word "staurós" ("cross") as "torture stake" because Jehovah’s Witnesses do not believe that Jesus was crucified on a cross. The New World Translation does not translate the Greek words “sheol,” "hades,” "gehenna," and "tartarus," as "hell” because Jehovah’s Witnesses do not believe in hell. The NWT gives the translation "presence" instead of “coming” for the Greek word “parousia” because JW’s believe that Christ has already returned in the early 1900’s. In Colossians 1:16, the NWT inserts the word “other” despite it being completely absent from the original Greek text. It does this to give the view that “all other things” were created by Christ, instead of what the text says, “all things were created by Christ.” This is to go along with their belief that Christ is a created being, which they believe because they deny the Trinity.
The most well known of all the New World Translation perversions is John 1:1. The original Greek text reads, “the Word was God.” The NWT renders it has “the word was a god.” This is not a matter of correct translation, but of reading one's preconceived theology into the text, rather than allowing the text to speak for itself. There is no indefinite article in Greek (in English - "a" or "an"). So any use of an indefinite article in the English translation must be added in by the translator. This is grammatically acceptable in English, so long as it does not change the meaning of the text.
It is only the Watchtower's pre-conceived heretical beliefs that are behind the dishonest and inconsistent translation that is the New World Translation. The New World Translation is most definitely not a valid version of God’s Word. There are minor differences between all the major English translations of the Bible. No English translation is perfect. However, while other Bible translators make minor mistakes in the rendering of the Hebrew and Greek text into English; the NWT intentionally changes the rendering of the text to conform to Jehovah’s Witness’ theology. The New World Translation is a perversion, not a version, of the Bible.
