Confirmation, together with Baptism and Eucharist, form the Sacraments of Initiation that are all intimately connected. In the Sacrament of Confirmation, the baptized person is “sealed with the gift of the Holy Spirit” and is strengthened for service to the Body of Christ.
Jesus’ entire mission occurred in communion with the Spirit. Before He died, Jesus promised that the Spirit would be given to the Apostles and to the entire Church. After His death, He was raised by the Father in the power of the Spirit.
Confirmation brings an increase and deepening of baptismal grace:
-it roots us more deeply in the divine filiation [becoming adopted sons and daughters of God]
which makes us cry, “Abba! Father!”;
-it unites us more firmly to Christ;
-it increases the gifts of the Holy Spirit in us;
-it renders our bond with the Church more perfect;
-it gives us a special strength of the Holy Spirit to spread and defend the faith by word
and action as true witnesses of Christ, to confess the name of Christ boldly,
and never to be ashamed of the Cross
-CCC, no. 1303
As the words of the liturgy indicate the person being confirmed is sealed with the Holy Spirit. This seal is called a character, marking the person forever as called to fulfill the Church’s mission in all the circumstances of life.
Confirmation deepens our baptismal life that calls us to be missionary witnesses of Jesus Christ in our families, neighborhoods, society, and the world. Through Confirmation, our personal relationship with Christ is strengthened. We receive the message of faith in a deeper and more intensive manner with great emphasis given to the person of Jesus Christ, who asked the Father to give the Holy Spirit to the Church for building up the community in loving service.
The Holy Spirit bestows seven gifts
– wisdom, understanding, knowledge, fortitude, counsel, piety, and fear of the Lord –
to assist us in our mission and witness. The impact of these gifts accompanies us in the various
stages of our spiritual development.
When we are responsive to the grace of Confirmation and the seven gifts of the Holy Spirit, we begin to bear the fruits of the Spirit. The tradition of the Church names twelve fruits of the Holy Spirit: love, joy, peace, patience, kindness, goodness, generosity, gentleness, faithfulness, modesty, self-control, and chastity. (cf. CCC, no. 1832; Gal 5:22)
