ὄνομα τοῦ πατρὸς καὶ τοῦ υἱοῦ καὶ τοῦ ἁγίου πνεύματος ἐν ὕδατι ζῶντι.
2. ἐὰν δὲ μὴ ἔχῃς ὕδωρ ζῶν, εἰς ἄλλο ὕδωρ βάπτισον· εἰ δ’ οὐ δύνασαι ἐν ψυχρ , ἐν θερμ .
3. ἐὰν δὲ ἀμφότερα μὴ ἔχῃς, ἔκχεον εἰς τὴν κεφαλὴν τρὶς ὕδωρ εἰς ὄνομα πατρὸς καὶ υἱοῦ καὶ
ἁγίου πνεύματος.
4. πρὸ δὲ τοῦ βαπτίσμος προνηστευσάτω ὁ βαπτίζων καὶ ὁ βαπτιζόμενος48 καὶ εἴ τινες ἄλλοι
δύναται· κελεύεις49 δὲ νηστεῦσαι τὸν βαπτιζόμενον πρὸ μιᾶς ἢ δύο

But if you do not have living water, baptize in other water; if you cannot do it in cold, in heat. 3. if you don't have both, pour three waters on the head in the name of father and son and holy spirit. 4. before the baptism, the baptizer and the baptized should fast48 and if there are others it is possible; but you fast 49 the person being baptized before one or two
