CCC 1213

Holy Baptism is the basis of the whole Christian life, the gateway to life in the Spirit (vitae spiritualis ianua),⁴ Cf. Council of Florence: DS 1314DS — Denzinger–Schönmetzer (Enchiridion Symbolorum): vitae spiritualis ianua. 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 Roman Catechism II, 2, 5; Cf.
