Chapter I
What it celebrates
The Acts of the Apostles tells that on the day of Pentecost, fifty days after the resurrection, the apostles were gathered in Jerusalem when a sound like a rushing wind filled the house and tongues as of fire rested on each of them. Filled with the Holy Spirit, they began to speak in other languages, and pilgrims from many lands heard them in their own tongues. Peter preached to the crowd, and, Acts says, about three thousand were baptised that day.
The apostles had come together for Shavuot, the Jewish feast of weeks, fifty days after Passover. Christians came to see Pentecost as the completion of Easter and the beginning of the Church’s mission to the world.
Chapter II
How it is kept
In Catholic, Anglican and Lutheran churches the clergy wear red, the colour of fire, and the ancient hymns Veni Creator Spiritus and Veni Sancte Spiritus call on the Spirit. Many churches baptise or confirm on this day. The Monday after, Whit Monday, is a public holiday in much of Europe.
Orthodox churches celebrate Pentecost as the feast of the Holy Trinity. Churches and homes are decked with green branches, flowers and fresh grass, and the next day honours the Holy Spirit. In Romania, where the feast is called Rusalii, people bring branches of lime and walnut to church.
Chapter III
Around the world
In Rome, red rose petals are dropped through the opening of the Pantheon’s dome at the end of Mass. In Russia, birch branches fill the churches. Pentecostal churches, named after the feast and its gifts of the Spirit, now count hundreds of millions of members, especially in Africa, Latin America and Asia.
