One of the definitions for the word confirm is: ”to remove doubt about by authoritative act or indisputable fact” (Merriam-Webster). I think that is the perfect definition for what the sacrament of Confirmation is all about.
Pentecost and Confirmation are closely tied and have been that way from the beginning. In the Acts of the Apostles (8:14-18), Peter and John went to Samaria in order to lay hands and pray that the newly baptized would receive the Holy Spirit. Yet today, many people see Confirmation as a sort of graduation from religious education. We can never truly learn everything there is to know about the infinite God because we are finite human beings; however, that does not mean that we shouldn’t keep trying and learn as much as we are able.
The ordinary minister of Confirmation is a bishop, as they are seen as the successors of the Apostles, who were first to receive Confirmation directly by the Holy Spirit on Pentecost. Look at how the Holy Spirit affected the Apostles: they traveled far proclaiming the Good News and healing. They did what they saw Jesus do. It is through the prompting of the Holy Spirit they preached the indisputable fact that Jesus is the Christ — the Savior and Redeemer of the world.
While we do receive the Holy Spirit in baptism, Confirmation is that authoritative act by the bishop that leaves an indelible mark indicating we are Christians. Every Confirmation is just like the visit to Samaria by Peter and John. The bishop, along with the whole Church, prays for the Holy Spirit to descend into the hearts and souls of those being confirmed. We pray that each will know and accept their calling to proclaim and heal in Jesus’ name during their journey of life.
Pentecost Sunday is an opportunity for us to remember our own Confirmation and to reflect on how the Spirit has prompted us and how well we have listened. Rather than dwelling on any shortcomings, we learn from them and renew our vocation to spread the gospel by the grace the Holy Spirit gives us. There is no doubt that we are Christians, followers of Jesus Christ, as we have been confirmed in the Holy Spirit; we just need to put into practice what we believe.
