Where in the New Testament is there evidence of Christians keeping the Sabbath after the resurrection?
A. Evidence from the New Testament is uniform. Even decades the resurrection of Christ, Sunday (the first day) is not referred to as the Lord’s day as many claim it to be, and Saturday is always referred to as the Sabbath (see Matthew 28: 1; Mark 16:1-2; Luke 23:56; 24:1). Certainly it is true that Paul was a faithful Sabbath-keeper. As Christ’s custom was to go into the synagogue every Sabbath day (Luke 4:16), so it was the custom of Paul (Acts. 17:2). Some might say that he went to the synagogue because that is where the Jews were, but it is clear that he also took the Gentiles there (Acts 13:42-44; Acts 18:4). Clearly, there is no mandate, either by Christ or the apostles, for the change of the Sabbath from the seventh day to the first day of the week. This is why it took centuries before the Pagan custom of Sunday-keeping could be established across the major portions of Europe.
