He isn't but you are the one offering the confusion. The majority of Christianity reads, understand, embraces, and accepts that Jesus is God. If you read correctly, you'd discover your verse is lifted from the context of conflicting prophecies. This is typical abuse and problem I encounter with those who do not read according to proper English and language principles. It is rather haphazard and egocentrically selective. We have a number of such on TOL
In John 14, Philip was Jewish/Arian. He did not recognize the one-ness of Jesus with His Father. Philip believed that Jesus and God were two separate beings. I believe this in the sense that John 1:1 explains it: "...was with and was God." It is a strange dichotomy for finite man, but there it is, plain as day and as clear: "...was
with AND was God." Both/And. To read it 'either/or' is a great damage to language, scripture, and God. It is, in fact, a lie against this very clear verse.
In keeping with this, Jesus responded to Philip, who at the time didn't get this:
John 14:9 Jesus said to him, "Have I been with you so long, and you still do not know me, Philip? Whoever has seen me has seen the Father. How can you say, 'Show us the Father'?"
I do not believe you can be an Arian/Unitarian without being corrected by this.
The question again is, "Can you be a Christian if you deny Christ as God in your life?"
