The following is excerpted largely from my response to a reader who took me to task for my saying that the fourth commandment is not for Christians. A bit of it is also from an email to a brother who asked about 1 Timothy 1:8. The difficulty with the first reader goes beyond Sabbath keeping. It is the error of believing that we must keep the law to obtain or maintain justification. It is a leaven that has spread throughout Christianity (Galatians 5:9). These people ignore the Bible's plain words, such as these penned by Paul: "Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace" (Galatians 5:4).
Dear Mr. Sabbathkeeper,
You have written to me asking me whether, since I say that Christians are not obligated to keep the fourth commandment (“Remember the sabbath day, to keep it holy”), do I then believe that it is okay to murder, commit adultery, steal, lie, and covet, prohibitions against these also being found in the Ten Commandments.
