What is Confirmation? Good question!
confirmatio = strengthening, consolidation):
Confirmation, like Baptism and Eucharist, is one of the three sacraments of initiation of the Catholic Church. As the Holy Spirit descended upon the disciples who were gathered on Pentecost, so the Holy Spirit comes to every baptized person for whom the Church requests the gift of the Holy Spirit. It secures and strengthens him to be a living witness of Christ. Pretty sweet! (For more information see Catechism of the Catholic Church, 1285)
"Now when the apostles at Jerusalem heard that Samaria had received the word of God, they sent to them Peter and John, who came down and prayed for them that they might receive the Holy Spirit; for the Spirit had not yet fallen on any of them, but they had only been baptized in the name of the Lord Jesus." - Acts 8:14-16
The Archdiocese of Galveston Houston offers a two-year preparation for Confirmation including faith formation and sacramental catechesis. Candidates for Confirmation attend Confirmation classes, youth group, and retreats (at least one per year), and take part in service opportunities in their church and community as a part of this preparation.
