266. Why is this sacrament called Chrismation or Confirmation?  

(Comp 266) It is called Chrismation (in the Eastern Churches: Anointing with holy myron or chrism) because the essential rite of the sacrament is anointing with chrism. It is called Confirmation because it confirms and strengthens baptismal grace.

“In brief” 

(CCC 1316) Confirmation perfects Baptismal grace; it is the sacrament which gives the Holy Spirit in order to root us more deeply in the divine filiation, incorporate us more firmly into Christ, strengthen our bond with the Church, associate us more closely with her mission, and help us bear witness to the Christian faith in words accompanied by deeds. 

To deepen and explain  

(CCC 1289) Very early, the better to signify the gift of the Holy Spirit, an anointing with perfumed oil (chrism) was added to the laying on of hands. This anointing highlights the name "Christian," which means "anointed" and derives from that of Christ himself whom God "anointed with the Holy Spirit" (Acts 10:38). This rite of anointing has continued ever since, in both East and West. For this reason the Eastern Churches call this sacrament Chrismation, anointing with chrism, or myron which means "chrism." In the West, the term Confirmation suggests that this sacrament both confirms baptism, and strengthens baptismal grace.

On reflection  

(CCC 695) Anointing. The symbolism of anointing with oil also signifies the Holy Spirit (Cf. 1 Jn 2:20:27; 2 Cor 1:21), to the point of becoming a synonym for the Holy Spirit. In Christian initiation, anointing is the sacramental sign of Confirmation, called "chrismation" in the Churches of the East. Its full force can be grasped only in relation to the primary anointing accomplished by the Holy Spirit, that of Jesus. Christ (in Hebrew "messiah") means the one "anointed" by God's Spirit. There were several anointed ones of the Lord in the Old Covenant, pre-eminently King David (Cf. Ex 30:22-32; 1 Sam 16:13). But Jesus is God's Anointed in a unique way: the humanity the Son assumed was entirely anointed by the Holy Spirit. The Holy Spirit established him as "Christ" (Cf. Lk 4: 18-19; Isa 61:1). The Virgin Mary conceived Christ by the Holy Spirit who, through the angel, proclaimed him the Christ at his birth, and prompted Simeon to come to the temple to see the Christ of the Lord (Cf. Lk 2:11, 26-27). The Spirit filled Christ and the power of the Spirit went out from him in his acts of healing and of saving (Cf. Lk 4:1; 6:19; 8:46). Finally, it was the Spirit who raised Jesus from the dead (Cf. Rom 1:4; 8:11). Now, fully established as "Christ" in his humanity victorious over death, Jesus pours out the Holy Spirit abundantly until "the saints" constitute - in their union with the humanity of the Son of God - that perfect man "to the measure of the stature of the fullness of Christ" (Eph 4:13; cf. Acts 2:36): "the whole Christ," in St. Augustine's expression.
