"How can we offer the hope of peace, healing and harmony to those 'stations' of conflict, suffering and tension which you have chosen to march with this World Youth Day Cross? Unity and reconciliation cannot be achieved through our efforts alone," said the Pope. “God has made us for one another and only in God and his Church can we find the unity we seek.”
"Unity is the essence of the Church,” the Pontiff declared. “It is a gift we must recognize and cherish. Tonight, let us pray for the resolve to nurture unity: contribute to it! Resist any temptation to walk away! For it is precisely the comprehensiveness, the vast vision, of our faith- solid yet open, consistent yet dynamic, true yet constantly growing in insight- that we can offer our world."
It is because of your faith, that your friends turn to you in times of difficulty, the Pope explained. All humanity harbors a "cry for recognition, for belonging, for unity.”
“From the forlorn child in a Darfur camp, or a troubled teenager, or an anxious parent in any suburb, or perhaps even now from the depth of your own heart, there emerges the same human cry for recognition, for belonging, for unity. Who satisfies that essential human yearning to be one, to be immersed in communion, to be built up, to be led to truth? The Holy Spirit! This is the Spirit’s role: to bring Christ’s work to fulfillment. Enriched with the Spirit’s gifts, you will have the power to move beyond the piecemeal, the hollow utopia, the fleeting, to offer the consistency and certainty of Christian witness!”
The Pope told of how he decided to study the witnesses to the Holy Spirit whom he described as "the neglected person of the Blessed Trinity," which is how he discovered the works of the Saint Augustine. He proclaimed the lessons of St. Augustine, saying that "at first [Augustine] was suspicious of the Christian teaching that God had become man." Yet his experience of the love of God present in the Church led him to … three particular insights about the Holy Spirit."
The first was that "the 'Holy' and 'Spirit' refer to what is divine about God... what is shared by the Father and the Son." Hence, "Augustine concluded that the Spirit's particular quality is unity.
