Confirmation is the Sacrament in which baptized persons receive a special grace which strengthens them for the profession of Christian faith. Confirmation is usually conferred by the Bishop, who lays his hands on the recipients, making the sign of the Cross with chrism on their foreheads, while he says: "Be sealed with the gift of the Holy Spirit"
Those who receive Confirmation are given a special grace to profess the faith. By Confirmation they are enriched with the gifts of the Holy Spirit, and are more closely linked to the Catholic Church. They are made strong soldiers of Christ, and so they are more firmly obliged by word and deed to be faithful witnesses of Christ, spreading and defending the Catholic faith.
As the bishop exhorts them: "The gift of the Holy Spirit which you are about to receive will be a spiritual sign and seal to make you more like Christ and more perfect members of his Church ... You have already been baptized into Christ and now you will receive the power of his Spirit and the sign of the cross on your forehead. You must be his witnesses before all the world to his suffering, death and resurrection; your way of life should at all times reflect the goodness of Christ." (Rite of Confirmation 22)
