Scripture teaches that the Lord's Day is a set time for public worship and spiritual rest, commemorating Christ's resurrection. Reformed traditions hold that the fourth commandment establishes a perpetual moral obligation to dedicate one day in seven to the Lord, though some Lutheran and other traditions view its specific day-observance as an external matter of Christian liberty.
In the Reformed tradition, we understand the Sabbath to be rooted in a positive, moral, and perpetual commandment of God. As noted in the 1689 LBCF Ch.22 §7, the shift from the seventh day to the first day—the Lord's Day—marks the significance of the resurrection of Jesus Christ. This aligns with the Westminster Confession of Faith Ch.21 §7, which emphasizes that this appointment binds all men in all ages to set apart a day for God's worship, honoring the transition from the old creation to the new.

The Lord's Day is not a burden to earn God's favor, but a gracious opportunity to feast upon the finished work of Christ. We are invited into a Sabbath rest that points beyond itself to the final rest we have in Jesus. As Hebrews reminds us, there remains a Sabbath rest for the people of God, and in Christ, we are freed from the bondage of moralism to delight in Him. Hebrews 4:9-10 says: 'There remaineth therefore a sabbath rest for the people of God. For he that is entered into his rest hath himself also rested from his works, as God did from his.'

In the Reformed tradition, Sunday is considered the Christian Sabbath, binding upon believers as a perpetual moral duty to set aside one day in seven for worship and rest. Other traditions, such as the Lutheran view expressed in the Large Catechism, emphasize the freedom of the Christian and the necessity of order and instruction rather than the strict binding nature of the Old Testament ceremonial Sabbath.
The Reformed tradition, as articulated in the 1689 LBCF Ch.22 §7 and the Westminster Confession of Faith Ch.21 §7, holds that the fourth commandment is a positive, moral, and perpetual ordinance. While the seventh-day observance of the Old Testament was specific to that era, the resurrection of Christ established the first day of the week—the Lord's Day—as the permanent Christian Sabbath. This is not a matter of legalistic bondage, but a gospel-ordered rhythm for the people of God to cease from worldly labors and dedicate time to the public worship of the One who rested from His work of redemption. As Hebrews 4:9-10 states: "There remaineth therefore a sabbath rest for the people of God. For he that is entered into his rest hath himself also rested from his works, as God did from his own" (Hebrews 4:9-10).

Conversely, the Lutheran tradition, as reflected in the Large Catechism — The Third Commandment, argues that the external observance of a specific day is part of the ceremonial order and is not strictly binding upon Christians in the same legal sense. In this view, the command is fulfilled not by rest itself, but by the sanctification of the Word. We keep Sunday for the sake of good order and the needs of our neighbors, that they may hear the gospel. For the believer, every day is meant to be holy in Christ; we do not obey to be accepted, but because we are already accepted in the Beloved, we order our lives to hear His voice. As Colossians 2:16 reminds us: "Let no man therefore judge you in meat, or in drink, or in respect of a feast day or a new moon or a sabbath day" (Colossians 2:16).
