"The Son who speaks to the Father exists and they are both one in the Spirit, who constitutes, so to speak, the atmosphere of giving and loving which makes them one God. This unity of love which is God, is a unity far more sublime than the unity of a last indivisible particle could be. The Triune God himself is the one and only God. Through Jesus let us as it were cast a glance at God in his intimacy. John, in his Gospel, expressed it like this: '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).For the entire address, click here: Pope Benedict XVI on Vigil of Pentecost
Yet Jesus did not only let us see into God's intimacy; with him, God also emerged, as it were, from his intimacy and came to meet us. This happened especially in his life, passion, death and Resurrection; in his words.
Jesus, however is not content with coming to meet us. He wants more. He wants unification. This is the meaning of the images of the banquet and the wedding.
Not only must we know something about him, but through him we must be drawn to God. For this reason he had to die and be raised, since he is now no longer to be found in any specific place, but his Spirit, the Holy Spirit, emanates from him and enters our hearts, thereby uniting us with Jesus himself and with the Father, the Triune God.
