Holy Baptism is the basis of the whole Christian life, the gateway to life in the Spirit (vitae spiritualis ianua), 4 and the door which gives access to the other Sacraments. Through Baptism we are freed from Sin and reborn as Sons of God; we become Members of Christ, are incorporated into the Church and made Sharers in her Mission: "Baptism is the Sacrament of regeneration through Water in the word." 5
