CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 974–977

974 The Most Blessed Virgin Mary, when the course of her earthly life was completed, was taken up body and soul into the glory of heaven, where she already shares in the glory of her Son's Resurrection, anticipating the resurrection of all members of his Body.
975 "We believe that the Holy Mother of God, the new Eve, Mother of the Church, continues in heaven to exercise her maternal role on behalf of the members of Christ" (Paul VI, CPG § 15).
976 The Apostle's Creed associates faith in the forgiveness of sins not only with faith in the Holy Spirit, but also with faith in the Church and in the communion of saints. It was when he gave the Holy Spirit to his apostles that the risen Christ conferred on them his own divine power to forgive sins: "Receive the Holy Spirit. If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained."

(Part Two of the catechism will deal explicitly with the forgiveness of sins through Baptism, the sacrament of Penance, and the other sacraments, especially the Eucharist. Here it will suffice to suggest some basic facts briefly.)

977 Our Lord tied the forgiveness of sins to faith and Baptism: "Go into all the world and preach the gospel to the whole creation. He who believes and is baptized will be saved." Baptism is the first and chief sacrament of forgiveness of sins because it unites us with Christ, who died for our sins and rose for our justification, so that "we too might walk in newness of life."
