CCC,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."
The Effects of Confirmation
CCC,1302 It is evident from its celebration that the effect of the sacrament of Confirmation is the special outpouring of the Holy Spirit as once granted to the apostles on the day of Pentecost.
CCC,1303 From this fact, Confirmation brings an increase and deepening of baptismal grace:
CCC,1304 Like Baptism which it completes, Confirmation is given only once, for it too imprints on the soul an indelible spiritual mark, the “character,” which is the sign that Jesus Christ has marked a Christian with the seal of his Spirit by clothing him with power from on high so that he may be his witness.
CCC,1305 This “character” perfects the common priesthood of the faithful, received in Baptism, and “the confirmed person receives the power to profess faith in Christ publicly and as it were officially (quasi ex officio).”
Who Can Receive This Sacrament?
CCC,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.
CCC,1307 For centuries, Latin custom has indicated “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.
CCC,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.
CCC,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.
CCC,1310 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.
CCC,1311 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.
