Just as Baptism gives new life, Eucharist nourishes life, and Reconciliation restores life when it is broken, Confirmation strengthens that life by the gifts of the Holy Spirit (cf. CCC 1285). It is about strengthening what God has given, and continues to give, to his sons and daughters (cf. CCC 1302-1303).
The Sacrament of Confirmation helps a person remain faithful to his or her baptismal commitment to witness to Christ and to serve others. The gifts of the Holy Spirit associated with Confirmation are strengths (or virtues) that Christian living requires if it is to be fruitful and complete. Thus, wisdom, understanding, knowledge, counsel, fortitude, piety, and fear of the Lord, are divine aids to Christian living without which fulfilling one’s baptismal calling would be far more difficult, if not impossible.
