Πᾶν τὸ ὄντως ὂν ἢ πρὸ αἰῶνός ἐστιν, ἢ ἐν τῷ αἰῶνι, ἢ μετέχον αἰῶνος. Ὅτι μὲν γάρ ἐστι πρὸ αἰῶνος, δέδεικται. ἀλλὰ μὴν καὶ ἐν τῷ αἰῶνι. ὁ γὰρ αἰὼν τὸ ἀεὶ μετὰ τοῦ ὄντος ἔχει καὶ τὸ μετέχον αἰῶνος. τὸ γὰρ αἰώνιον πᾶν μεθέξει καὶ τοῦ ἀεὶ καὶ τοῦ ὄντος. τοῦτο μὲν κατὰ μέθεξιν ἄμφω ἔχει, καὶ τὸ ἀεὶ καὶ τὸ ὄν. ὁ δὲ αἰὼν τὸ μὲν ἀεὶ πρώτως, τὸ δὲ ὂν κατὰ μέθεξιν· τὸ δὲ ὂν αὐτὸ πρώτως ὄν ἐστιν.

Everything that is truly being is either before eternity, or in eternity, or participating in eternity. That there is what is before eternity has been shown. But there is also what is in eternity, for eternity holds the always together with being; and there is what participates in eternity. For everything eternal will participate both in the always and in being. This last has both by participation, both the always and being; eternity has the always primarily and being by participation; and being itself is being primarily.

Thomas's cited source for LdC 2 (the threefold placing of true being relative to eternity). Creuzer's note (3) records that the printed edition had a lacuna sign *** here which he filled from codex A — so this sentence is Creuzer's supplement, and any English must not present it as uncontested. Phase 3 translation note — editorial supplement, do not read as uncontested text. Creuzer's note (3) states that the printed edition carried a lacuna sign (***) between αἰῶνος and τοῦτο μὲν and that he filled it from codex A. On the text as printed, that locates the supplement exactly at the sentence 'τὸ γὰρ αἰώνιον πᾶν μεθέξει καὶ τοῦ ἀεὶ καὶ τοῦ ὄντος' — rendered here as 'For everything eternal will participate both in the always and in being.' The English translates it because Creuzer's text carries it, but on any crux page it is Creuzer's supplement from a single manuscript, not transmitted text. Creuzer's note (1) further records that the edition read πάντως τὸ ὄντως ὄν in the lemma, where A gives πᾶν τὸ ὄντως, which is what he prints and what is translated. αἰών is 'eternity' and αἰώνιος 'eternal' here, as at El. 87.
