“Confirmation is a special outpouring of the Holy Spirit like that of Pentecost. This outpouring impresses on the soul an indelible character and produces a growth in the grace of Baptism. It roots the recipient more deeply in divine sonship, binds him more firmly to Christ and to the Church and reinvigorates the gifts of the Holy Spirit in his soul. It gives a special strength to witness to the Christian faith.”
From the Compendium of the Catechism of the Catholic Church #268
The Sacrament of Confirmation confers a permanent (indelible) mark on the soul of the recipient, gifting the recipient with the fullness of God’s seven-fold Gifts, which in turn produce great fruits in the soul of the believer.
Normally in our diocese, children receive this Sacrament in or around 10th grade. In order to receive Confirmation, a child must attend two full years of approved religious instruction either in parish catechetical program, Catholic school, or an approved homeschool program.
