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 and women. 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.
Pope St John Paul II, May 18, 1997
