The Sacrament of Confirmation is one of the 3 Sacraments of Initiation.
Like Baptism, Confirmation leaves an indelible spiritual mark which cannot be erased and repeated. We belong totally to God and our service is to him forever.
The graces (supernatural gifts) of Confirmation are: 1) enriching and deepening our Baptismal grace, 2) empowering us to be rooted in Christ, 3) strengthening our bond with the Church, 4) bearing witness to the faith and defending it through our words and actions, and 5) increasing the gifts of the Holy Spirit in us.
The matter (visible signs) are: the anointing with chrism (perfumed) oil and laying on of hands.
The form (words) are: "Be sealed with the gift of the Holy Spirit."
