Holy Baptism is the foundation of the entire Christian life, the gateway to spiritual life (vitae spiritualis ianua), and the door that allows access to the other sacraments. We are freed from sin and reborn as sons of God through Baptism; we become members of Christ, are incorporated into the Church, and made partners in her mission: "Baptism is the sacrament of regeneration through water in the word" (CCC, 1213)
