Through Baptism, God enables us to participate in his life in Jesus Christ and makes us his children. It is through this sacrament that we receive the Holy Spirit and become members of the People of God, of the Body of Christ, which is the Church. Baptism becomes our commitment to grow in this new life and to strive to acquire spiritual maturity. By baptism, God purifies us from sin.Baptism is the sacrament of faith which has the Risen Christ as its source, and it is the offer of salvation for all people. Intimately linked to Confirmation and to Eucharist, Baptism is, with these two sacraments, Christian Initiation. The child is baptized in the faith of their parents, godparents and of the Church.
