In Christianity, they believe in the 10 commandments as the foundation to their faith. Amongst those commandments is the commandment to keep the Sabbath Day holy. Interesting that they say they believe in keeping the Sabbath Day holy, yet there is little evidence that they understand what that means, when it is, or regard it as an important commandment.
Then in Judaism they regard the Sabbath as a very special day; however, they believe they are the only ones that have to keep the Sabbath Day holy and the rest of the world doesn’t have to.
