What does the Gospel of John teach? The answer of prominent Bible scholar Adela Yarbro Collins is as follows:
”In the Gospel it is clear that Jesus, as word or logos philosophically understood, is preexistent and divine in the sense of being an emanation of God or being ‘a god’ … God’s first creature, namely, the only-begotten god.” (Pages 202/3)
In response to a colleague who described Jesus as “a fully divine being” in the Gospel of John, Collins responded: :”it is not clear what Casey means by ‘a fully divine being’ here. If he means something like the second person of the trinity, it is doubtful that John 1 supports this interpretation.” (Page176) King and Messiah as Son of God: Divine , Human and Angelic Figures in Biblical and Related Literature (2008)
It’s also interesting to note that the Jewish writer Philo, writing a few decades earlier than the Gospel of John, described the Word/Logos as: “[God’s] first-born word, the eldest of his angels, as the great archangel of many names”. On the Confusion of Tongues 146
