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."˜Catechism of the Catholic Church
The Sacrament of Confirmation is the third Sacrament of Initiation in which the Holy Spirit confers His gifts through the anointing by the Bishop (or delegated priest) with the Sacred Chrism in order to strengthen the confirmandi (those being confirmed) to be more faithful witnesses to Christ and their faith and to participate more fully in the evangelical mission of the Church. It is in this sacrament in which the confirmandi , after years of being formed in their faith, now make the Profession of Faith, which was made for them at their Baptism, on their own.
