Many Sabbatarian Christians say that since Christ kept the Sabbath, we should follow His example and do the same. But do they extend this to other parts of the law that Jesus, living as a Jew, most likely kept? Do most Sabbatarian Christians keep the feast of unleavened bread (Exodus 23:15), the feast of harvest (Exodus 23:16), or the feast of ingathering (Exodus 23:16)? Why the focus on this part of the law and not the others? It seems inconsistent to insist on the observance of one or more parts of the law while ignoring other parts. While it is true that Christ kept the law before His death and resurrection, He did so to fulfill prophecy and to redeem us, who were under the law. This can be found in Isaiah 26, Luke 24, and Galatians 4.

Isaiah 26:12
"LORD, Thou wilt establish peace for us, Since Thou hast also performed for us all our works."

Luke 24:44
"Now He said to them, 'These are My words which I spoke to you while I was still with you, that all things which are written about Me in the Law of Moses and the Prophets and the Psalm must be fulfilled.'"

It is interesting to see in this passage that Paul criticizes the Christians of Galatia for turning back to what he described as "weak and worthless elemental things." He defines them in verse 10 as "days and months and seasons and years." While some may say that he was speaking only of pagan holidays and festival days or ceremonial days of the Mosaic Law, it seems most likely that Paul was disturbed by the influence of some Jewish Christians (referred to usually as Judaizers) on the Gentile Christians there, who were telling them that they had to keep the ceremonial days of the Mosaic Law in order to be saved, including the weekly Sabbath. There is really no way one could reasonably separate a weekly Sabbath from the "days and months and seasons and years." Paul included everything here. All holy days of the Mosaic Law. And he expressed concern that perhaps his efforts in teaching the Gospel to them was in vain.

This is one of the clearest passages in the New Testament telling of the passing of the Ten Commandments of the Old Covenant in favor of living in accordance with the Holy Spirit in the New Covenant, since we become children of Abraham by faith rather than by works. Paul says here very clearly that we are to "cast out" the law that was given on Mount Sinai. And that law includes the Ten Commandments, since it was the only one given on that mountain. So when one accepts Christ, one lives, not according a law that has served its purpose in leading to Christ, but by the guidance of the Holy Spirit, who enables a person to live a life that is pleasing to God.
