The faithful are sealed with the Holy Spirit in order to be more effective witnesses to the Gospel through confirmation. In the Chaldean Rite, the sacrament of Confirmation and the sacrament of Baptism are performed in the same ritual.

“Confirmation perfects Baptismal grace; it is the sacrament which gives the Holy Spirit in order to root us more deeply in the divine filiation, incorporate us more firmly into Christ, strengthen our bond with the Church, associate us more closely with her mission, and help us bear witness to the Christian faith in words accompanied by deeds” (CCC, 1316).
