Confirmation is a Catholic Sacrament of mature Christian commitment and a deepening of baptismal gifts. It is one of the three Sacraments of Initiation for Catholics. It is most often associated with the gifts of the Holy Spirit.
1285 Baptism, the Eucharist, and the sacrament of Confirmation together constitute the "sacraments of Christian initiation," whose unity must be safeguarded. It must be explained to the faithful that the reception of the sacrament of Confirmation is necessary for the completion of baptismal grace. For "by the sacrament of Confirmation, [the baptized] are more perfectly bound to the Church and are enriched with a special strength of the Holy Spirit. Hence they are, as true witnesses of Christ, more strictly obliged to spread and defend the faith by word and deed."
IV. Who can Receive This Sacrament?
1306 Every baptized person not yet confirmed can and should receive the sacrament of Confirmation. Since Baptism, Confirmation, and Eucharist form a unity, it follows that "the faithful are obliged to receive this sacrament at the appropriate time," for without Confirmation and Eucharist, Baptism is certainly valid and efficacious, but Christian initiation remains incomplete.
1307 The Latin tradition gives "the age of discretion" as the reference point for receiving Confirmation. But in danger of death children should be confirmed even if they have not yet attained the age of discretion.
1308 Although Confirmation is sometimes called the "sacrament of Christian maturity," we must not confuse adult faith with the adult age of natural growth, nor forget that the baptismal grace is a grace of free, unmerited election and does not need "ratification" to become effective. St. Thomas reminds us of this: "Age of body does not determine age of soul. Even in childhood man can attain spiritual maturity: as the book of Wisdom says: "For old age is not honored for length of time, or measured by number of years.”Many children, through the strength of the Holy Spirit they have received, have bravely fought for Christ even to the shedding of their blood.
1309 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 this end catechesis for Confirmation should strive to awaken a sense of belonging to the Church of Jesus Christ, the universal Church as well as the parish community. The latter bears special responsibility for the preparation of confirmands.
