Yes, Jesus is the Son of God, Lord and Christ; the Light of the World and the Bread of Life; and the Way, Truth and Life. He is all of this for me, as a Christian who is also a historian of early Christianity.
And yet I do not think that Jesus spoke of himself with these grand terms and phrases.
Together with most mainstream scholars, I see the gospels as containing earlier and later layers of Christian traditions about Jesus as they developed during the first century. The gospels (and to some extent, the New Testament as a whole) contain the early Christian movement’s memory of Jesus and their testimony to what Jesus had become in early Christian experience, conviction and thought.
