In the Sacrament of Confirmation, the baptized person is sealed with the gift of the Holy Spirit and is strengthened for service to the Body of Christ.
The prophets of the Old Testament foretold that God’s Spirit would rest upon the Messiah to sustain his mission. Their prophecy was fulfilled when Jesus conceived by the Spirit and born of the Virgin Mary lived in communion with the Spirit. At his baptism by John, the Spirit descended upon him. Before his death, Jesus promised that the Spirit would be given to the Apostles and to the entire Church.
Confirmation deepens our baptismal life. It calls us to be missionary-witnesses of Jesus Christ in our families, neighborhoods, society, and the world. In a more profound way we receive the message of faith, with special emphasis on Jesus Christ, who asked the Father to give the Holy Spirit to the Church for building up the community in loving service.
