Dialogue with Trypho

Justin: 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. 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.
