THE SACRAMENT OF CONFIRMATION [from the Catechism of the Catholic Church]
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.89 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.”90
THE SIGNS AND THE RITE OF CONFIRMATION
1293 In treating the rite of Confirmation, it is fitting to consider the sign of anointing and what it signifies and imprints: a spiritual seal.
Anointing, in Biblical and other ancient symbolism, is rich in meaning: oil is a sign of abundance and joy;103 it cleanses (anointing before and after a bath) and limbers (the anointing of athletes and wrestlers); oil is a sign of healing, since it is soothing to bruises and wounds;104 and it makes radiant with beauty, health, and strength.
1294 Anointing with oil has all these meanings in the sacramental life. The pre-baptismal anointing with the oil of catechumens signifies cleansing and strengthening; the anointing of the sick expresses healing and comfort. The post-baptismal anointing with sacred chrism in Confirmation and ordination is the sign of consecration. By Confirmation Christians, that is, those who are anointed, share more completely in the mission of Jesus Christ and the fullness of the Holy Spirit with which he is filled, so that their lives may give off “the aroma of Christ.”105
1295 By this anointing the confirmand receives the “mark,” the seal of the Holy Spirit. A seal is a symbol of a person, a sign of personal authority, or ownership of an object.106 Hence soldiers were marked with their leader’s seal and slaves with their master’s. A seal authenticates a juridical act or document and occasionally makes it secret.107
1296 Christ himself declared that he was marked with his Father’s seal.108 Christians are also marked with a seal: “It is God who establishes us with you in Christ and has commissioned us; he has put his seal on us and given us his Spirit in our hearts as a guarantee.”109 This seal of the Holy Spirit marks our total belonging to Christ, our enrollment in his service for ever, as well as the promise of divine protection in the great eschatological trial.110
