After Jesus ascended into Heaven, He fulfilled His promise to send the Holy Spirit to guide His Church. On the first Pentecost He sent the Holy Spirit to the Apostles. The Catholic Church came into existance at the death of Jesus on the Cross. The Church was made manifest to the world on the first Pentecost when the Apostles were filled with the Holy Spirit and became changed men. No longer afraid or timid, they went forth to the whole world to spread the teachings of Jesus and bring people into the True Church by Baptism. When anyone is baptized they receive the Three Theological Virtues, the Four Moral Virtues and Seven Gifts of the Holy Spirit. They become 'new persons', anxious and able to spread the Kingdom of God. It was felt that this stained glass window carries this message to those who behold it.
