This is the context in which we need to read the conclusion of the prologue to John’s Gospel: “No one has ever seen God; it is the only Son, who is nearest to the Father’s heart, who has made him known” (Jn 1:18). It is in Jesus that the promise of the new prophet is fulfilled. What was true of Moses only in fragmentary form has now been fully realized in the person of Jesus: He lives before the face of God, not just as a friend, but as a Son; he lives in the most intimate unity with the Father.
