From “How to become a Christian”: Chapter 7 – The Ten Commandments – proof that you and I are sinners, not just other people
Observing the sabbath day
This is the only one of the Ten Commandments which no longer applies to us. We are no longer under an obligation to observe a particular day of rest. However, it’s still a very good thing to have a day of rest. The Jewish people were commanded to refrain from working on the sabbath, i.e. Friday sunset to Saturday sunset. That commandment was not restated in the New Testament, whereas the other nine were.
Thus the other nine commandments still apply, even to Christians, but the commandment about the sabbath does not, because we are not bound by the law of Moses. We are only bound by those parts of it that were restated in the New Testament, or which our own consciences tell us to obey. However, in that case, it is your conscience you would be obeying, not the Law of Moses itself. So, I will now move on to the Fifth Commandment.
