The sacrament of Confirmation is the special outpouring of the Holy Spirit as once granted to the apostles on the day of Pentecost.
From this fact, Confirmation brings an increase and deepening of baptismal grace. It unites us more firmly to Christ; it increases the gifts of the Holy Spirit in us; it renders our bond with the Church more perfect; and it gives us a special strength of the Holy Spirit to spread and defend the faith by word and action as true witnesses of Christ, to confess the name of Christ boldly, and never to be ashamed of the Cross:
Like Baptism which it completes, Confirmation is given only once.
Preparation for Confirmation should aim at leading the Christian toward a more intimate union with Christ and a more lively familiarity with the Holy Spirit—his actions, his gifts, and his biddings—in order to be more capable of assuming the apostolic responsibilities of Christian life.
To receive Confirmation one must be in a state of grace. One should receive the sacrament of Penance in order to be cleansed for the gift of the Holy Spirit. More intense prayer should prepare one to receive the strength and graces of the Holy Spirit with docility and readiness to act.
Candidates for Confirmation, as for Baptism, fittingly seek the spiritual help of a sponsor. To emphasize the unity of the two sacraments, it is appropriate that this be one of the baptismal godparents
A candidate for Confirmation who has attained the age of reason must profess the faith, be in the state of grace, have the intention of receiving the sacrament, and be prepared to assume the role of disciple and witness to Christ, both within the ecclesial community and in temporal affairs.
The essential rite of Confirmation is anointing the forehead of the baptized with sacred chrism (in the East other sense-organs as well), together with the laying on of the minister’s hand and the words: “Accipe signaculum doni Spiritus Sancti” (Be sealed with the Gift of the Holy Spirit).
