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 Eph. iv. 5. : for only the heretics are re-baptized 36 This sentence is omitted in one ms. (Paris, 1824), but probably only through the repetition of the word “baptism.” On the laws of the Church against the repetition of Baptism, and concerning the re-baptism of heretics, see Tertull. de Baptismo, c. xv: Apost. Const. xv.: Bingham, xii. 5: Hefele, Councils, Lib. I. c. 2: Dictionary Christian Antiq. I. p. 167 a. , 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.
