2. In the very beginning of the letter Petilianus said: "Petilianus, a bishop, to his well-beloved brethren, fellow-priests, and deacons, appointed ministers with us throughout our diocese in the gospel, grace be to you and peace, from God our Father and from the Lord Jesus Christ."
3. Augustine answered: I acknowledge the apostolic greeting. You see who you are that employ it, but see from what source you have learned what you say. For in these terms Paul salutes the Romans, and in the same terms the Corinthians, the Galatians, the Ephesians, the Colossians, the Philippians, the Thessalonians. What madness is it, therefore, to be unwilling to share the salvation of peace with those very Churches in whose epistles you learned its form of salutation?
Chap. II.—4. Petilianus said: "Those who have polluted their souls with a guilty laver, under the name of baptism, reproach us with baptizing twice,—than whose obscenity, indeed, any kind of filth is more cleanly, seeing that through a perversion of cleanliness they have come to be made fouler by their washing."
5. Augustine answered: We are neither made fouler by our washing, nor cleaner by yours. But when the water of baptism is given to any one in the name of the Father, and of the Son, and of the Holy Ghost, it is neither ours nor yours, but His of whom it was said to John, "Upon whom thou shalt see the Spirit descending, and remaining on Him, the same is He which baptizeth with the Holy Ghost."[684]
Chap. III.—6. Petilianus said: "For what we look to is the conscience of the giver, to cleanse that of the recipient."
7. Augustine answered: We therefore need have no anxiety about the conscience of Christ. But if you assert any man to be the giver, be he who he may, there will be no certainty about the cleansing of the recipient, because there is no certainty about the conscience of the giver.
