Justin Martyr, Dialogue with Trypho

“But if we do not admit this, we shall be liable to fall into foolish opinions, as if it were not the same God who existed in the times of Enoch and all the rest, who neither were circumcised after the flesh, nor observed Sabbaths, nor any other rites, seeing that Moses enjoined such observances; or that God has not wished each race of mankind continually to perform the same righteous actions: to admit which, seems to be ridiculous and absurd. Therefore we must confess that He, who is ever the same, has commanded these and such like institutions on account of sinful men, and we must declare Him to be benevolent, foreknowing, needing nothing, righteous and good. But if this be not so, tell me, sir, what you think of those matters which we are investigating.” And when no one responded: “Wherefore, Trypho, I will proclaim to you, and to those who wish to become proselytes, the divine message which I heard from that man.58 The man he met by the sea-shore. Do you see that the elements are not idle, and keep no Sabbaths? Remain as you were born. For if there was no need of circumcision before Abraham, or of the observance of Sabbaths, of feasts and sacrifices, before Moses; no more need is there of them now, after that, according to the will of God, Jesus Christ the Son of God has been born without sin, of a virgin sprung from the stock of Abraham. For when Abraham himself was in uncircumcision, he was justified and blessed by reason of the faith which he reposed in God, as the Scripture tells. Moreover, the Scriptures and the facts themselves compel us to admit that He received circumcision for a sign, and not for righteousness. So that it was justly recorded concerning the people, that the soul which shall not be circumcised on the eighth day shall be cut off from his family. And, furthermore, the inability of the female sex to receive fleshly circumcision, proves that this circumcision has been given for a sign, and not for a work of righteousness. For God has given likewise to women the ability to observe all things which are righteous and virtuous; but we see that the bodily form of the male has been made different from the bodily form of the female; yet we know that neither of them is righteous or unrighteous merely for this cause, but [is considered righteous] by reason of piety and righteousness.

[23] Ἐὰν δὲ ταῦτα οὕτως μὴ ὁμολογήσωμεν, συμβήσεται ἡμῖν εἰς ἄτοπα ἐμπίπτειν νοήματα, ὡς τοῦ αὐτοῦ θεοῦ μὴ ὄντος τοῦ κατὰ τὸν Ἑνὼχ καὶ τοὺς ἄλλους πάντας, οἳ μήτε περιτομὴν τὴν κατὰ σάρκα ἔχοντες μήτε σάββατα ἐφύλαξαν μήτε δὲ τὰ ἄλλα Μωυσέως ἐντειλαμένου ταῦτα ποιεῖν, ἢ τὰ αὐτὰ αὐτὸν δίκαια μὴ ἀεὶ πᾶν γένος ἀνθρώπων βεβουλῆσθαι πράσσειν: ἅπερ γελοῖα καὶ ἀνόητα ὁμολογεῖν φαίνεται. δι' αἰτίαν δὲ τὴν τῶν ἁμαρτωλῶν ἀνθρώπων τὸν αὐτὸν ὄντα ἀεὶ ταῦτα καὶ τὰ τοιαῦτα ἐντετάλθαι ὁμολογεῖν, καὶ φιλάνθρωπον καὶ προγνώστην καὶ ἀνενδεῆ καὶ δίκαιον καὶ ἀγαθὸν ἀποφαίνειν ἔστιν. ἐπεὶ εἰ μὴ ταῦτα οὕτως ἔχει, ἀποκρίνασθέ μοι, ὦ ἄνδρες, περὶ τῶν ζητουμένων τούτων ὅ τι φρονεῖτε. Καὶ μηδὲν μηδενὸς ἀποκρινομένου: Διὰ ταῦτά σοι, ὦ Τρύφων, καὶ τοῖς βουλομένοις προσηλύτοις γενέσθαι κηρύξω ἐγὼ θεῖον λόγον, ὃν παρ' ἐκείνου ἤκουσα τοῦ ἀνδρός. ὁρᾶτε ὅτι τὰ στοιχεῖα οὐκ ἀργεῖ οὐδὲ σαββατίζει. μείνατε ὡς γεγένησθε. εἰ γὰρ πρὸ τοῦ Ἀβραὰμ οὐκ ἦν χρεία περιτομῆς οὐδὲ πρὸ Μωυσέως σαββατισμοῦ καὶ ἑορτῶν καὶ προσφορῶν, οὐδὲ νῦν, μετὰ τὸν κατὰ τὴν βουλὴν τοῦ θεοῦ διὰ Μαρίας τῆς ἀπὸ γένους τοῦ Ἀβραὰμ παρθένου γεννηθέντα υἱὸν θεοῦ Ἰησοῦν Χριστόν, ὁμοίως ἐστὶ χρεία. καὶ γὰρ αὐτὸς ὁ Ἀβραὰμ ἐν ἀκροβυστίᾳ ὢν διὰ τὴν πίστιν, ἣν ἐπίστευσε τῷ θεῷ, ἐδικαιώθη καὶ εὐλογήθη, ὡς ἡ γραφὴ σημαίνει: τὴν δὲ περιτομὴν εἰς σημεῖον, ἀλλ' οὐκ εἰς δικαιοσύνην ἔλαβεν, ὡς καὶ αἱ γραφαὶ καὶ τὰ πράγματα ἀναγκάζει ἡμᾶς ὁμολογεῖν. ὥστε δικαίως εἴρητο περὶ ἐκείνου τοῦ λαοῦ, ὅτι ἐξολοθρευθήσεται ἡ ψυχὴ ἐκείνη ἐκ τοῦ γένους αὐτῆς, ἣ οὐ περιτμηθήσεται τῇ ἡμέρᾳ τῇ ὀγδόῃ. καὶ τὸ μὴ δύνασθαι δὲ τὸ θῆλυ γένος τὴν σαρκικὴν περιτομὴν λαμβάνειν δείκνυσιν ὅτι εἰς σημεῖον ἡ περιτομὴ αὕτη δέδοται, ἀλλ' οὐχ ὡς ἔργον δικαιοσύνης: τὰ γὰρ δίκαια καὶ ἐνάρετα ἅπαντα ὁμοίως καὶ τὰς θηλείας δύνασθαι φυλάσσειν ὁ θεὸς ἐποίησεν. ἀλλὰ σχῆμα μὲν τὸ τῆς σαρκὸς ἕτερον καὶ ἕτερον ὁρῶμεν γεγενημένον ἄρρενος καὶ θηλείας, διὰ δὲ τοῦτο οὐδὲ δίκαιον οὐδὲ ἄδικον οὐδέτερον αὐτῶν ἐπιστάμεθα, ἀλλὰ δι' εὐσέβειαν καὶ δικαιοσύνην.
