Confirmation is the sacrament of initiation in which a baptized Catholic, through prayers, imposition of hands and the anointing with chrism, receives a special outpouring of the Holy Spirit that completes Baptismal grace. This sacrament impresses a character, and by it the baptized, continuing on the path of Christian initiation, are enriched by the gifts of the Holy Spirit and bound more perfectly to the Church. It strengthens them and obliges them more firmly to be witnesses to Christ by word and deed and to spread and defend the faith! The confirmation process helps the candidate prepare for the Sacrament of Confirmation through the evangelizing and catechizing opportunities they offer.

In him you also, who have heard the word of truth, the gospel of your salvation, and have believed in him, were sealed with the promised holy Spirit.
Ephesians 1:13
