John Chrysostom on the Sabbath

"[W]hen he [God] said, ‘You shall not kill’ . . . he did not add, ‘because murder is a wicked thing.’ The reason was that conscience had taught this beforehand, and he speaks thus, as to those who know and understand the point. Wherefore when he speaks to us of another commandment, not known to us by the dictate of conscience, he not only prohibits, but adds the reason. When, for instance, he gave commandment concerning the Sabbath— ‘On the seventh day you shall do no work’—he subjoined also the reason for this cessation. What was this? ‘Because on the seventh day God rested from all his works which he had begun to make’ [Ex. 20:10-11]. . . . For what purpose then, I ask, did he add a reason respecting the Sabbath, but did no such thing in regard to murder? Because this commandment was not one of the leading ones. It was not one of those which were accurately defined of our conscience, but a kind of partial and temporary one, and for this reason it was abolished afterward. But those which are necessary and uphold our life are the following: ‘You shall not kill. . . . You shall not commit adultery. . . . You shall not steal.’ On this account he adds no reason in this case, nor enters into any instruction on the matter, but is content with the bare prohibition" (Homilies on the Statutes 12:9 [A.D. 387]).

"You have put on Christ, you have become a member of the Lord and been enrolled in the heavenly city, and you still grovel in the law [of Moses]? How is it possible for you to obtain the kingdom? Listen to Paul’s words, that the observance of the law overthrows the gospel, and learn, if you will, how this comes to pass, and tremble, and shun this pitfall. Why do you keep the Sabbath and fast with the Jews?" (Homilies on Galatians 2:17 [A.D. 395]).

"The rite of circumcision was venerable in the Jews’ account, forasmuch as the law itself gave way thereto, and the Sabbath was less esteemed than circumcision. For that circumcision might be performed, the Sabbath was broken; but that the Sabbath might be kept, circumcision was never broken; and mark, I pray, the dispensation of God. This is found to be even more solemn than the Sabbath, as not being omitted at certain times. When then it is done away, much more is the Sabbath" (Homilies on Philippians 10 [A.D. 402]).
