Was Jesus a separate god? The New World Translation of John 1 seems to indicate that Jesus was a separate god from the Father.

1 In [the] beginning the Word was, and the Word was with God, and the Word was a god.
2 This one was in [the] beginning with God.
3 All things came into existence through him, and apart from him not even one thing came into existence.

How does the concept of the trinity fit with this concept of Jesus being a separate God?
The verse in question is:


  Ἐν ἀρχῇ ἦν ὁ λόγος, καὶ ὁ λόγος ἦν πρὸς τὸν θεόν, καὶ θεὸς ἦν ὁ
  λόγος.


That bold part is, somewhat literally, "God the word was".

The issue here is the lack of the indefinite article in Greek. They had no word for "a, an". Depending on context, it is acceptable and even necessary to insert those words into a translation. The question is whether or not it is appropriate here.

I think not, for lots of reasons. John and all the apostles were Jews, monotheists, and if they were teaching some new polytheism, wouldn't it have shown up in more places than an ambiguous Greek sentence?

edit in response to @Sotiris' comment:

Greek usually uses the definite article in front of proper nouns, which is probably what you're getting at. But in this case the lack of the article before θεὸς is easily explainable. A word-by-word translation would be "God was the word". Word order is flexible in Greek, and since both θεὸς and λόγος are in the nominative case, it would be impossible to determine which is the subject and which is the predicate nominative except for the placement of the article. ὁ λόγος clearly identifies λόγος as the subject, but ὁ θεὸς ἦν ὁ λόγος would be ambiguous (God was the word, or the word was God?).
