Is the Sabbath a ceremonial law or moral law?
The Law of Moses (ceremonial law) was written separately on paper by Moses and was stored on the “outside” of the Ark of the Covenant (Deuteronomy 31:24-26). The Ten Commandments on the other hand was written in stone by God personally and stored on the “inside” of the Ark of the Covenant (Exodus 31:18; Deuteronomy 10:5). To quote the obvious, if the Lord’s Sabbath was a Mosaic Law, it would have been written in the Mosaic Law! But it is a moral law and why God wrote it and placed it in His Ten Commandment law because that is exactly what it is and where it belongs.
The ceremonial law (Mosaic Law) was instituted 430 years after God made the covenant with Abraham, (Galatians 3:17-19) while the Lord's Sabbath was made at creation before sin had even entered the world. The ceremonial law was added because of transgressions, and hence was an added because of sin, and consisted of animal sacrifices to make atonement for sin before Christ permanently took the place of this law by becoming the Lamb of God that took away the sins of the world. Thus there is no way the Lord's Sabbath can be a ceremonial Sabbath. The fourth Commandment is called "the Sabbath of the Lord thy God.” (Exodus 8-11) It is the Lord's Sabbath and was “never” practised because of sin. God did not make a mistake when He put His Sabbath in His moral law instead of the ceremonial law, which did have all the ceremonial sabbaths! God put His Sabbath exactly where it belonged.
Jesus while referring to the destruction of Jerusalem in 70 A.D. said, “And pray that your flight may not be in winter or on the Sabbath.” Matthew 24:20 The ceremonial law (Mosaic Law) was nailed to the cross and yet Jesus shows everyone was still keeping the Sabbath forty years after the cross and yet even further proof it cannot be a ceremonial sabbath that were nailed to the cross. Isaiah 66:22-23 says, “For as the new heavens and the new earth, which I will make … and from one Sabbath to another, shall ALL flesh come to worship before me, saith the LORD.” We keep the Lord's Sabbath in the New Heaven and Earth that also proves the Lord's Sabbath is eternal and a moral law. So God is vindicated and is not some fool or the author of confusion that made a serious blunder when He put His Sabbath in His moral law. I would have hope that most Christians would never be foolish enough to believe He did! Read is the Sabbath a ceremonial law or moral law for very detailed information.
