It's Whitsun this Lord's Day, when we remember Jesus' outpouring of the Holy Spirit on His Church after His ascension. So here's a three minute video on the Holy Spirit and the Church. It's based on Tenet Catechism 6.4:
Q. What does the Holy Spirit do for the Church, the Body of Christ?
A. The Holy Spirit glorifies Christ the Head of the Church, unites the Church to Christ her Head, builds the Church up in Christ through the Word and the gifts, and always points the Church and her members more and more to Christ.
