During the Last Supper, after Jesus affirmed that to know him was also to know the Father (cf. Jn 14: 7), Philip quite ingenuously asks him: "Lord, show us the Father, and we shall be satisfied" (Jn 14: 8). Jesus answered with a gentle rebuke: "Have I been with you so long, and yet you do not know me, Philip? He who has seen me has seen the Father: how can you say, "Show us the Father?' Do you not believe that I am in the Father and the Father in me?... Believe me that I am in the Father and the Father in me" (Jn 14: 9-11). These words are among the most exalted in John's Gospel. They contain a true and proper revelation. At the end of the Prologue to his Gospel, John says: "No one has ever seen God; the only Son, who is in the bosom of the Father, he has made him known" (Jn 1: 18). Well, that declaration which is made by the Evangelist is taken up and confirmed by Jesus himself, but with a fresh nuance. (…) To express ourselves in accordance with the paradox of the Incarnation we can certainly say that God gave himself a human face, the Face of Jesus, and consequently, from now on, if we truly want to know the Face of God, all we have to do is to contemplate the Face of Jesus! In his Face we truly see who God is and what he looks like! (Pope Benedict XVI, General Audience, 6 September 2006)
