The Sabbath was an old testament type.. It foreshadowed Jesus . Jesus is the Lord of the Sabbath ... Remember that the curtain in the temple was rent from the top to the bottom ..showing the end of the rituals , the sacrifices and entering into a New, but better Covenant ... Jesus is our Sabbath rest .. we can cease from “working” and rest in Him in faith
God gave the Sabbath to the Israelites as a sign between God and the Israelites (Ex. 31:17). The Sabbath made the Israelites different from other nations—but Paul says that the laws that separated Jews and Gentiles have been done away by the cross of Christ (Eph. 2:11-18).... There is no longer a law to keep the Sabbath ..that type was fulfilled ...
The 4th commandment has not been abrogated; none of the ten commandments have been abrogated.
The 4th commandment is a Creation ordinance, instituted by God not only before the Israelites, but before the fall of Adam into sin. Since at that point there was no sin in the world, thus no need of a Savior, the Sabbath ordinance can not be ceremonial.
