Gen 2:1-3
(Gen 2:1) Thus the heavens and the earth were finished, and all the host of them.
(Gen 2:2) And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made.
(Gen 2:3) And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.
Sabbatarians often use this text to show the importance of the Sabbath, and even that Adam kept the Sabbath.
But the words “Adam knew about the Sabbath” are not in the text. The text does NOT say that Adam rested. It says that GOD rested.
Sabbatarians tell us that when God wrote the 10 commandments for his people, who had been captives for 400 years, He was reminding them of their beginning. Yes, he was. And by keeping Sunday, we are remembering – and celebrating – OUR roots as Christians. We no longer even WANT to remember our roots in sinful Adam, because we have been rescued from that. Before Christ, we were part of a creation that turned to sin. After Christ, we are part of a new sinless creation. And it is on Sunday that we remember and celebrate this.
