(2) It is more logical to believe that the epic teachings of this passage came first from the lips of Jesus, rather than from John.  This verse is the heart of Christianity; and to identify it as coming from the reflections of a Spirit-guided John so long afterward is simply unreasonable.

They forget that the function of the Spirit in the apostles was to help them remember what Jesus said (John 14:26).
