ACC ~ 1 Peter 3 v21

THE MEANING OF BAPTISM. CYPRIAN: Peter showed and vindicated the unity of the church by commanding and warning that we can be saved only through the baptism of the one church. Just as in that baptism of the world by which the ancient iniquity was purged, the one who was not in the ark could not be saved through water, so now anyone who has not been baptized in the church cannot be saved, for the church has been founded in the unity of the Lord, as the sacrament of the one ark. LETTERS 74.11.

A CLEAR CONSCIENCE. AUGUSTINE: If some people have the worst consciences, full of every fault and crime, unchanged by penance for their evil deeds, baptism nevertheless saves them, for on the basis of the foundation which is laid in baptism they will be saved, even if it is through fire. EIGHT QUESTIONS OF DULCITIUS 1.

SAVED THROUGH BAPTISM. ANDREAS: The water of the flood is a type of baptism because it both punished evil people and saved the good, just as baptism expels evil spirits and saves those who turn to Christ. This shows the great power of baptism, and how much we need it. CATENA.
