The Sacrament of Confirmation is necessary for the completion of baptismal grace.
For the Sacrament of Confirmation, the baptized are more perfectly bound to the Church and are enriched with a special strength of the Holy Spirit.
The purpose of adult confirmation is to invite the adult to a moment of conversion, reconciliation, and strengthening of their relationship with Jesus and the Church and to invite the adults to follow in His Way as disciples.
If you are a baptized Catholic, 19 or older, out of high school and have received First Communion, but for whatever reason, have not been confirmed, these preparation sessions are for you.
