7. We may not receive Baptism twice or thrice; else it might be said, Though I have failed once, I shall set it right a second time: whereas if thou fail once, the thing cannot be set right; for there is one Lord, and one faith, and one baptism 35 : for only the heretics are re-baptized 36 , because the former was no baptism.
Οὐκ ἔνι δὶς καὶ τρὶς λαβεῖν τὸ λουτρόν: ἐπεὶ ἦν εἰπεῖν: Ἅπαξ ἀποτυχὼν, δεύτερον κατορθῶ: ἐὰν δὲ τὸ ἅπαξ ἀποτύχῃς, ἀδιόρθωτον τὸ πρᾶγμα. Εἷς γὰρ Κύριος, καὶ μία πίστις, καὶ ἓν βάπτισμα: μόνον γὰρ αἱρετικοί τινες ἀναβαπτίζονται: ἐπειδὴ τὸ πρότερον οὐκ ἦν βάπτισμα.
