Praying thus, the Church unceasingly professes her faith that there exists in our created world a Spirit who is an uncreated gift. He is the Spirit of the Father and of the Son: like the Father and the Son he is uncreated, without limit, eternal, omnipotent, God, Lord. This Spirit of God "fills the universe," and all that is created recognizes in him the source of its own identity, finds in him its own transcendent expression, turns to him and awaits him, invokes him with its own being. Man turns to him, as to the Paraclete, the Spirit of truth and of love, man who lives by truth and by love, and who without the source of truth and of love cannot live. To him turns the Church, which is the heart of humanity, to implore for all and dispense to all those gifts of the love which through him "has been poured into our hearts." To him turns the Church, along the intricate paths of man's pilgrimage on earth: she implores, she unceasingly implores uprightness of human acts, as the Spirit's work; she implores the joy and consolation that only he, the true Counselor, can bring by coming down into people's inmost hearts; the Church implores the grace of the virtues that merit heavenly glory, implores eternal salvation, in the full communication of the divine life, to which the Father has eternally "predestined" human beings, created through love in the image and likeness of the Most Holy Trinity.
-Saint John Paul II, Dominum et vivificantem
