"But if some, through weak-mindedness, wish to observe such institutions as were given by Moses (from which they expect some virtue, but which we believe were appointed by reason of the hardness of the people's hearts), along with their hope in this Christ, and [wish to perform] the eternal and natural acts of righteousness and piety, yet choose to live with the Christians and the faithful, as I said before, not inducing them either to be circumcised like themselves, or to keep the Sabbath, or to observe any other such ceremonies, then I hold that we ought to join ourselves to such, and associate with them in all things as kinsmen and brethren." Justin's language shows that there were Sabbath-keeping Christians in his time. Such of them as were of Jewish descent no doubt generally retained circumcision. But it is very unjust in him to represent the Gentile Sabbath-keepers as observing this rite. That there were many of these is evident from the so-called "Apostolical Constitutions," and even from the Ignatian Epistles. One good thing, however, Justin does say. The keeping of the commandments he terms the performance of "the eternal and natural acts of righteousness." He would consent to fellowship those who do these things provided they made them no test for others. He well knew in such case that the Sabbath would die out in a little time. Himself and the more popular party at Rome honored as their festival the day observed by the heathen Romans, as he reminds the emperor in his Apology, and he was willing to fellowship the Sabbath-keepers if they would not test him by the commandments, _i. e._, if they would fellowship him in violating them. That Justin held to the abrogation of the ten commandments is also manifest. Trypho, in the tenth chapter of the Dialogue, having said to Justin, "You do not obey his commandments," and again, "You do not observe the law," Justin answers in chapter xi. as follows:-- "But we do not trust through Moses, or through the law; for then we would do the same as yourselves. But now--for I have read that there shall be a final law, and a covenant, the chiefest of all, which it is now incumbent on all men to observe, as many as are seeking after the inheritance of God. For the law promulgated on Horeb is now old, and belongs to yourselves alone; but this is for all universally. Now, law placed against law has abrogated that which is before it, and a covenant which comes after in like manner has put an end to the previous one."
