But as to their scrupulosity concerning meats, and their superstition as respects the Sabbaths, and their boasting about circumcision, and their fancies about fasting and the new moons, which are utterly ridiculous and unworthy of notice,—I do not12 think that you require to learn anything from me. For, to accept some of those things which have been formed by God for the use of men as properly formed, and to reject others as useless and redundant,—how can this be lawful? And to speak falsely of God, as if He forbade us to do what is good on the Sabbath-days,—how is not this impious? And to glory in the circumcision13 of the flesh as a proof of election, and as if, on account of it, they were specially beloved by God,—how is it not a subject of ridicule? And as to their observing months and days,14 as if waiting upon15 the stars and the moon, and their distributing,16 according to their own tendencies, the appointments of God, and the vicissitudes of the seasons, some for festivities,17 and others for mourning,—who would deem this a part of divine worship, and not much rather a manifestation of folly? I suppose, then, you are sufficiently convinced that the Christians properly abstain from the vanity and error common [to both Jews and Gentiles], and from the busy-body spirit and vain boasting of the Jews; but you must not hope to learn the mystery of their peculiar mode of worshipping God from any mortal.

Ἀλλὰ μὴν τό γε περὶ τὰς βρώσεις αὐτῶν ψοφοδεές, καὶ τὴν περὶ τὰ σάββατα δεισιδαιμονίαν, καὶ τὴν τῆς περιτομῆς ἀλαζονείαν, καὶ τὴν τῆς νηστείας καὶ νουμηνίας εἰρωνείαν, καταγέλαστα καὶ οὐδενὸς ἄξια λόγου, οὐ νομίζω σε χρῄζειν παρ' ἐμοῦ μαθεῖν. Τό τε γὰρ τῶν ὑπὸ τοῦ Θεοῦ κτισθέντων εἰς χρῆσιν ἀνθρώπων ἃ μὲν ὡς καλῶς κτισθέντα παραδέχεσθαι, ἃ δ' ὡς ἄχρηστα καὶ περισσὰ παραιτεῖσθαι, πῶς οὖν θέμις ἐστί; τὸ δὲ καταψεύδεσθαι Θεοῦ ὡς κωλύοντος ἐν τῇ τῶν σαββάτων ἡμέρᾳ καλόν τι ποιεῖν, πῶς οὐκ ἀσεβές; τὸ δὲ καὶ τὴν μείωσιν τῆς σαρκὸς μαρτύριον ἐκλογῆς ἀλαζονεύεσθαι ὡς διὰ τοῦτο ἐξαιρέτως ἠγαπημένους ὑπὸ Θεοῦ, πῶς οὐ χλεύης ἄξιον; τὸ δὲ παρεδρεύοντας αὐτοὺς ἄστροις καὶ σελήνῃ τὴν παρατήρησιν τῶν μηνῶν καὶ τῶν ἡμερῶν ποιεῖσθαι, καὶ τὰς οἰκονομίας Θεοῦ καὶ τὰς τῶν καιρῶν ἀλλαγὰς καταδιαιρεῖν πρὸς τὰς αὐτῶν ὁρμάς, ἃς μὲν εἰς ἑορτάς, ἃς δὲ εἰς πένθη· τίς ἂν θεοσεβείας καὶ οὐκ ἀφροσύνης πολὺ πλέον ἡγήσεται τὸ δεῖγμα; τῆς μὲν οὖν κοινῆς εἰκαιότητος καὶ ἀπάτης καὶ τῆς Ἰουδαίων πολυπραγμοσύνης καὶ ἀλαζονείας ὡς ὀρθῶς ἀπέχονται Χριστιανοί, ἀρκούντως σε νομίζω μεμαθηκέναι. Τὸ δὲ τῆς ἰδίας αὐτῶν θεοσεβείας μυστήριον μὴ προσδοκήσῃς δύνασθαι παρὰ ἀνθρώπου μαθεῖν.
