Catechism of the Catholic Church

d and e. Para. 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 (Cf. Roman Ritual, Rite of Confirmation [OC], Introduction 1). 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" (LG 11; cf. OC, Introduction 2).
Para. 1313: In the Latin Rite, the ordinary minister of Confirmation is the bishop (Cf. CIC, can. 882). If the need arises, the bishop may grant the faculty of administering Confirmation to priests (Cf. CIC, can. 884 § 2), although it is fitting that he should confer it himself, mindful that the celebration of Confirmation has been temporally separated from Baptism for this reason. . . .
