The Christian Sabbath is the doctrine that the fourth commandment—‘Remember the sabbath day, to keep it holy’—abides as a perpetual moral law binding upon Christians, with the day transferred, by Christ’s resurrection and apostolic authority, from the seventh day of the week to the first, now called the Lord’s Day. The Reformed tradition (especially the Westminster Standards) grounds the Sabbath in three pillars. First, it is a creation ordinance: God Himself rested on the seventh day, blessed it, and sanctified it, instituting the Sabbath at the creation, before the Fall and before Israel, as a perpetual ordinance for all mankind. Second, it is part of the moral law: the fourth commandment stands in the heart of the Decalogue, written by God’s own finger on the tables of stone, among the perpetual moral commands, not the ceremonial laws that passed away with Christ. Third, the change of day rests on the resurrection of Christ and the practice of the apostolic church, which gathered on the first day; the substance of the commandment (one day in seven, kept holy to God) abides, while the particular day shifted from the seventh to the first, fittingly, for the new creation in Christ dates from His rising. The Sabbath is thus not a Jewish ceremony abolished at the cross but a perpetual gift rooted in creation and the moral law, now kept as the Lord’s Day. It is to be kept holy—a day of rest from ordinary labors and a day given to the worship of God—and it is both a duty and a delight, a weekly token of the covenant, and a foretaste of the eternal rest that remains for the people of God. Those who deny the Christian Sabbath argue that the fourth commandment was wholly ceremonial and is abolished, that all days are now alike, and that the New Testament does not explicitly command Sabbath-keeping; the Reformed reply that the commandment is moral and perpetual, rooted in creation, that the apostolic church plainly honored the first day, and that the abiding principle—the setting apart of one day in seven for rest and the worship of God—is God’s gracious and perpetual provision for His people, fulfilled and continued, not abolished, under the gospel.
Webster 1828 defines SABBATH as a day of rest; among Christians, the first day of the week, kept as holy time in commemoration of Christ’s resurrection.
SABBATH, n. — 1. The day which God appointed to be observed by the Jews as a day of rest from all secular labor or employments... 2. Among Christians, the first day of the week, called the Lord’s day, is observed in commemoration of the resurrection of Christ. 3. Intermission of pain or sorrow; time of rest.
The Christian Sabbath is the first day of the week, kept holy as a day of rest and worship.
Genesis 2:3 — "And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made."
Exodus 20:8 — "Remember the sabbath day, to keep it holy."
Mark 2:27-28 — "And he said unto them, The sabbath was made for man, and not man for the sabbath: Therefore the Son of man is Lord also of the sabbath."
Hebrews 4:9 — "There remaineth therefore a rest to the people of God."
This involves an intramural debate. The Christian Sabbath is denied by those who hold the fourth commandment wholly abolished (all days alike), and corrupted by the legalism that adds man-made rules or the laxity that empties the day of holy rest.
The Christian Sabbath is the subject of genuine debate among orthodox Christians. Some—including many Lutherans, dispensationalists, and others—hold that the fourth commandment was wholly ceremonial and is abolished in Christ, that under the new covenant all days are alike, and that the New Testament nowhere explicitly commands Sabbath-keeping, appealing to passages where Paul seems to relativize the observance of days. The Reformed reply that the Sabbath is rooted in creation (before Israel and the ceremonial law), that the fourth commandment stands among the perpetual moral law of the Decalogue, and that the apostolic church plainly honored the first day; the day changed, but the commandment abides. This is a serious exegetical debate among brethren who agree on the lordship of Christ, and it should be conducted with mutual charity.
Beyond this debate lie two practical corruptions. The legalistic corruption—the Pharisaical and sometimes Puritan excess—buries the day under man-made prohibitions, multiplying petty rules until the Sabbath becomes a burden and a snare rather than the delight God intended; this our Lord rebuked, declaring the Sabbath made for man and Himself its Lord. The lax corruption—far more common today—empties the day of holy rest and worship altogether, treating it as common time for labor and amusement, and so forfeiting both the commandment’s blessing and the resurrection’s memorial. The Reformed doctrine, rightly held, steers between: the Christian Sabbath is a perpetual gift rooted in creation and the moral law, kept now as the Lord’s Day—a day set apart from common labor for rest and the worship of God, kept not as a grievous yoke nor neglected as a common day, but embraced as a delight, a covenant token, and a weekly foretaste of the eternal rest that remains for the people of God.
The doctrine rests on the shabbāth (rest) God instituted at creation and commanded in the Decalogue—the abiding rest (sabbatismos) for the people of God, kept now on the Lord’s Day.
"The Christian Sabbath holds the fourth commandment perpetual, the day transferred to the first by Christ’s resurrection."
"It rests on three pillars: a creation ordinance, the moral law of the Decalogue, and the apostolic change of day."
"Some hold the Sabbath wholly abolished; the Reformed answer that the commandment abides though the day has changed."
