Roast with fire, not raw, not boiled
[...] With such water then we are commanded not to boil the Savior's flesh, I mean the words of the scriptures, nor to mix with the sayings another matter that can water them down through the boiling, but to partake of them cooking them with the fire alone — that is, with the divine Spirit — neither chewing them raw nor boiled in water.
Greek
κα ... Τοιοῦ[τῳ οὖν ὕδατι κελευ]όμεθ[α μὴ συνέψειν τὰς τοῦ] σ(ωτῆ)ρ(ο)ς σάρ[κας, λέγω δὴ τὰς λέξεις] τῶν γρ[αφῶν, μηδὲ ἐπιμίσγειν] το[ῖς] ῥ[ητοῖς ἑτέραν ὕ]λην ἐξυδαροῦν δυναμένην διὰ τῆς συνεψήσεως αὐτά, ἀλλὰ μόνῳ τῷ πυρί, τοῦτ' ἔστιν τῷ θείῳ πν(εύματ)ι, ἕψοντας μεταλαμβάνειν αὐτῶν, μήτε ὠμὰς αὐτὰς <τρώγοντας> μήτε ὕδατι ἡψημένας.
