Pentecost is a Jewish festival that occurs 50 days after Passover. It commemorates the descent of the Holy Spirit upon the Apostles and is one of the most important feast days in the Christian faith. The Holy Spirit arrived with seven gifts for the Apostles that are also received through the sacrament of Confirmation: wisdom, understanding, knowledge, counsel, fortitude, piety, and fear of the Lord. On Pentecost, about 3,000 people converted after hearing the Apostles preach empowered by the Holy Spirit.
