What is Baptism?

Baptism takes away original sin, all personal sins and all punishment due to sin. It makes the baptized person a participant in the divine life of the Trinity through sanctifying grace, the grace of justification which incorporates one into Christ and into his Church. It gives one a share in the priesthood of Christ and provides the basis for communion with all Christians. It bestows the theological virtues and the gifts of the Holy Spirit. A baptized person belongs forever to Christ. He is marked with the indelible seal of Christ (character). (Compendium of the Catechism of the Catholic Church, 263).
