Pentecost, a Christian holiday celebrated 49 days after Easter, commemorates the descent of the Holy Spirit upon the Apostles of Jesus in Jerusalem. This event occurred while they were observing the Feast of Weeks, as recounted in the Acts of the Apostles. The Catholic Church also recognizes the Holy Spirit's descent upon Mary, Jesus' mother, at this time, also documented in the Acts of the Apostles. Pentecost is a significant event in Christian theology, marking the birth of the Church and the empowerment of believers through the Holy Spirit.
