Ok , got to be honest most of the posts on this thread have been very long so l have skimmed through . However l have got the general gist of the discussion.
So a bit of digging later this is my contribution. Before Jesus , the man , was born the Hellenistic Jewish philosopher Philo identified the Angel of the Lord in the OT with the Logos, the Word of God . Now obviously John describes Jesus as the Word ( Logos )
Was John familiar with the idea that the Angel of the Lord being the Logos ? We don't know but his wording , pardon the pun , is interesting
Justin Martyr believed that the man who wrestled Jacob was the Angel of the Lord . Jacob claimed that he had seen God face to face. Now Jesus said that no one had seen the Father only the son . So Justin's reasoning was that it was God the Son who Jacob saw .
I believe that the general thought in the WT is that the teaching of the Trinity came at the Council of Nicea . However Justin lived from 100ad to 165ad so the ideas of at least two people in the Godhead and the Divinity of Christ were around long before that.
