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.88 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."89
1315 "Now when the apostles at Jerusalem heard that Samaria had received the word of God, they sent to them Peter and John, who came down and prayed for them that they might receive the Holy Spirit; for it had not yet fallen on any of them, but they had only been baptized in the name of the Lord Jesus. Then they laid their hands on them and they received the Holy Spirit" (⇒ Acts 8:14-17).
1317 Confirmation, like Baptism, imprints a spiritual mark or indelible character on the Christian's soul; for this reason one can receive this sacrament only once in one's life.
The Minister of Confirmation - Canon Law
Can. 882
The ordinary minister of confirmation is a Bishop; a presbytr provided with this faculty in virtue of universal law or the special grant of the competent authority also confers this sacrament validly.
Can. 883 The following possess the faculity of administering confirmation by the law itself:
#1 withint he boundaries of their jurisdiction, those who are equivalent in law to a diocesan bishop;
# 2 as regards the person in question, the presbyter who by virtue of office or mandate of the diocesan bishop baptizes one who is no longer an infant or admits one already baptized into the full communion of the Catholic Church;
#3 as regards those who are in danger of death, the pastor or indeed any presbyter.
