This biblical text from the Book of Acts describes the arrival of the Holy Spirit upon Jesus' followers on the Day of Pentecost, marked by a sound like wind and tongues of fire. Miraculously, the believers began to speak in different languages, allowing them to communicate with the diverse Jewish pilgrims in Jerusalem. Peter then addressed the bewildered crowd, explaining this event as the fulfillment of prophecy and proclaiming Jesus as Lord and Messiah, leading to thousands being baptised and forming a community of believers. The early church is depicted as a fellowship devoted to teaching, sharing, and worship.
