“Through Baptism we are freed from sin and reborn as children of God; we become members of Christ, are incorporated into the Church and made sharers in her mission”Catechism of the Catholic Church, 1213-1274
Baptism is the first Sacrament of Initiation. Through baptism, a person is cleansed of all sin, reborn, and sanctified in Christ through water and the Holy Spirit.
The Grace of Baptism
For the forgiveness of sins: In those who have been reborn nothing remains that would impede their entry into the Kingdom of God, neither Adam’s sin, nor personal sin, nor the consequences of sin, the gravest of which is separation from God (Catechism of the Catholic Church, 1263).
“A new creature”: Baptism makes us an adopted child of God giving us sanctifying grace through the Most Holy Trinity. This grace enables the baptized to believe in God, hope in him, and to love him. It also allows them to grow in goodness through the moral virtues
Incorporated in the Church, the Body of Christ: From the baptismal fonts is born the one People of God of the New Covenant, which transcends all the natural or human limits of nations cultures, races, and sexes: “For by one Spirit we were all baptized into one body” (Catechism of the Catholic Church, 1267).
The sacramental bond of the unity of Christians: Baptism constitutes the foundation of communion among all Christians, including those who are not yet in full communion with the Catholic Church. Those who are incorporated into Christ have a right to be called Christians and with good reason are accepted as brothers and sisters by the children of the Catholic Church (Catechism of the Catholic Church, 1271).
An indelible spiritual mark: Baptism seals the Christian with the indelible spiritual mark of his belonging to Christ. The baptismal seal enables and commits Christians to serve God by a vital participation in the holy liturgy of the Church and to exercise their baptismal priesthood by the witness of holy lives and practical charity. No sin can ever erase this mark (Catechism of the Catholic Church, 1272-1273).
