“Go therefore and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit, teaching them to observe all that I have commanded of you” (Matthew 28:19-20). Baptism is the first sacrament celebrated in the process of becoming a full member of the Church community. It is the first of the three Sacraments of Initiation – Baptism, Confirmation and Eucharist. Baptism is, like all the sacraments, a gift from God. Water is the universal symbol. Water is absolutely essential for all life. Water cleanses and restores. It is the waters of Baptism which give us new life. In accordance, through Baptism we also die to our old sinful selves in order to be restored and resurrected in the new life of Christ.
The fruit of Baptism, or baptismal grace, is a rich reality that includes forgiveness of original sin and all personal sins, birth into the new life by which man becomes an adoptive son of the Father, a member of Christ and a temple of the Holy Spirit. By this very fact the person baptized is incorporated into the Church, the Body of Christ, and made a sharer in the priesthood of Christ. Catechism of the Catholic Church, 1279
