CCC 1214

This sacrament is called Baptism, after the central rite by which it is carried out: to baptize (Greek baptizein) means to "plunge" or "immerse"; the "plunge" into the water symbolizes the catechumen's burial into Christ's death, from which he rises up by resurrection with him, as "a new creature."⁶ 2 Cor 5:17; Gal 6:15; Cf. Rom 6:3-4; Col 2:12.
