The Church Fathers taught that the Logos was begotten from the Father rather than being created out of nothing. For example, Justin Martyr (second century) wrote that "God has begotten of Himself a certain rational Power as a Beginning before all other creatures. The Holy Spirit indicates this Power by various titles, sometimes the Glory of the Lord, at other times Son, or Wisdom, or Angel, or God, or Lord, or Word." (Dialogue with Trypho, Chapter 61) Justin illustrated this, saying, "We can observe a similar example in nature when one fire kindles another, without losing anything, but remaining the same; yet the enkindled fire seems to exist of itself and to shine without lessening the brilliancy of the first fire." (same text)
The NWT itself, at John 1:18, refers to the Logos-Christ as "the only-begotten god". We are talking here of a real god, because he is generated out of the Father and so must be a divine offspring. Even if we accept the NWT rendering of John 1:1, "the Word was a god," the Word must be a real god, and not a god in name only. But since there is only one God, not two, there must be some way in which these two divine Personages remain a unity.
Tertullian attempted to illustrate divine unity as follows:
"For God sent forth the Word, as the Paraclete also declares. This is just as the root puts forth the tree, the fountain the river, and the sun the ray. For these are emanations of the substances from which they proceed. I should not hesitate, indeed, to call the tree the son or offspring of the root; or the river, that of the fountain, or the ray, that of the sun. . . . Now, the Spirit indeed is third from God and the Son. Just as the fruit of the tree is third from the root, or as the stream out of the river is third from the fountain, or as the apex of the ray is third from the sun. Nothing, however, is alien from that original source from which it derives its own properties. In like manner, the Trinity, flowing down from the Father through intertwined and connected steps, does not at all disturb the 'Monarchy,' while it at the same time guards the state of the 'Economy.'" (Against Praxeas) The Monarcy refers to the Unity of God, and the Economy to the Threeness.
The Fathers were against the heresy of Modalism, which claims that the one God merely poses as three different persons. They taught that there is a real distinction between the Father, Son and Holy Spirit. This is why the WT can quote the Fathers favorably. But where the WT and the Fathers part company is that the WT claims the Logos was created, whereas the Fathers taught that the Logos is begotten of the Father and so is actually divine as the Father is divine. The WT is like Arius of the fourth century, who claimed that the Logos was created out of nothing (like the rest of creation). But the WT avoids ever mentioning this fine distinction which is so crucial.
