Q. 71. Where has Christ promised us that he will certainly wash us by his blood and Spirit, as we are washed with the water of baptism?

Question. Where has Christ promised us that he will certainly wash us by his blood and Spirit, as we are washed with the water of baptism?

Answer. In the institution of baptism, which is thus expressed: “Go ye, therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost” (Matt. 28;19): “he that believeth and is baptized, shall be saved, but he that believeth not shall be damned” (Mark 16;16). This promise is also repeated, where the scripture calls baptism “the washing of regeneration” (Titus 3;5), and “the washing away of sins” (Acts 22;16).
