Dominum et Vivificantem: On the Holy Spirit in the Life of the Church and the World
16 It is precisely the Messiah himself who is this path. In the Old Covenant, anointing had become the external symbol of the gift of the Spirit. The Messiah (more than any other anointed personage in the Old Covenant) is that single great personage anointed by God himself He is the Anointed One in the sense that he possesses the fullness of the Spirit of God. He himself will also be the mediator in granting this Spirit to the whole People. Here in fact are other words of the Prophet: "The Spirit of the Lord God is upon me, because the Lord has anointed me to bring good tidings to the afflicted; he has sent me to bind up the brokenhearted to proclaim liberty to the captives, and the opening of the prison to those who are bound; to proclaim the year of the Lord's favor." The Anointed One is also sent "with the Spirit of the Lord ": "Now the Lord God has sent me and his Spirit." According to the Book of Isaiah, the Anointed One and the One sent together with the Spirit of the Lord is also the chosen Servant of the Lord upon whom the Spirit of God comes down: "Behold my servant, whom I uphold, my chosen, in whom my soul delights; I have put my Spirit upon him." We know that the Servant of the Lord is revealed in the Book of Isaiah as the true Man of Sorrows: the Messiah who suffers for the sins of the world. And at the same time it is precisely he whose mission will bear for all humanity the true fruits of salvation: "He will bring forth justice to the nations..." ; and he will become "a covenant to the people, a light to the nations..." ; "that my salvation may reach to the end of the earth." For: "My spirit which is upon you, and my words which I have put in your mouth, shall not depart out of your mouth, or out of the mouth of your children's children, says the Lord, from this time forth and for evermore." The prophetic texts quoted here are to be read in the light of the Gospel- just as, in its turn, the New Testament draws a particular clarification from the marvelous light contained in these Old Testament texts. The Prophet presents the Messiah as the one who comes in the Holy Spirit, the one who possesses the fullness of this Spirit in himself and at the same time for others, for Israel, for all the nations, for all humanity. The fullness of the Spirit of God is accompanied by many different gifts, the treasures of salvation, destined in a particular way for the poor and suffering, for all those who open their hearts to these gifts-sometimes through the painful experience of their own existence-but first of all through that interior availability which comes from faith. The aged Simeon, the "righteous and devout man" upon whom "rested the Holy Spirit," sensed this at the moment of Jesus' presentation in the Temple, when he perceived in him the "salvation...prepared in the presence of all peoples" at the price of the great suffering-the Cross- which he would have to embrace together with his Mother. The Virgin Mary, who "had conceived by the Holy Spirit," sensed this even more clearly, when she pondered in her heart the "mysteries" of the Messiah, with whom she was associated.
