Exodus 20:10
"God placed the Sabbath Commandment among the other nine commandments, which are generally acknowledged to be universally applicable precepts.
The very fact that God placed the Sabbath command in the heart of the Ten Commandments, accepted by all Christians as moral law, is in itself the most convincing proof that that the Sabbath command is moral law of universal applicability, not merely “ceremonial.”
How absurd to believe that, with weighty and eternally moral precepts on both sides of it, God should insert in their midst a ceremonial statute that was to expire at Christ's first advent!"
