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. * * * * * CHAP. IV.--8. PETILIANUS said: "For he who receives faith from the faithless, receives not faith but guilt." 9. AUGUSTINE answered: Christ is not faithless, from whom the faithful man receives not guilt but faith. For he believeth on Him that justifieth the ungodly, that his faith may be counted for righteousness.[685] * * * * * CHAP. V.--10. PETILIANUS said: "For everything consists of an origin and root; and if it have not something for a head, it is nothing: nor does anything well receive second birth, unless it be born again of good seed."
