The following four quotes are from homilies by St. Pope John Paul II on the Solemnity of Pentecost.
“The Church of Christ is always, so to speak, in a situation of Pentecost: she is always gathered in the Upper Room in prayer, and at the same time, driven by the powerful wind of the Spirit, she is always on the streets preaching” (June 8, 2003).
“Mary Most Holy, since Pentecost you have kept watch with the Church as she prays for the Holy Spirit: remain with us at the centre of our extraordinary Upper Room. To you, whom we venerate as Our Lady of Divine Love, we entrust the fruits of the City Mission, so that through your intercession the Diocese of Rome may offer the world a convinced witness to Christ our Saviour” (May 22, 1999).
“How can we not give thanks to God for the wonders the Spirit has never ceased to accomplish in these two millenniums of Christian life? Indeed, the event of grace at Pentecost has continued to bear its marvellous fruits, everywhere instilling apostolic zeal, a desire for contemplation, the commitment to live and serve God and our brothers and sisters with complete dedication” (May 31, 1998).
“In the Acts of the Apostles, St Luke describes the extraordinary manifestation of the Holy Spirit at Pentecost as a communication of the very vitality of God who gives himself to men. This divine gift is also light and power: light, to proclaim the Gospel, the Truth revealed by God; power, to infuse the courage of witnessing to the faith, which the Apostles begin at that very moment” (May 18, 1997).
