Sabbath

The CRCNA affirms the observance of the Christian Sabbath on Sunday, the Lord's Day. The Heidelberg Catechism (Q&A 103–104) teaches that the Fourth Commandment is morally binding on Christians. The specific day and ceremonial requirements (e.g., rest from all work) have been transferred to Sunday, which commemorates Christ's resurrection. The principle of the commandment — one day in seven for worship, rest, and renewal — is treated as a moral law that reflects the order of creation and God's rhythm of work and rest.

Unlike Seventh-day Adventism, which observes the Saturday Sabbath as a continuing obligation, the CRCNA sees Sunday as the proper day for Christian worship. This shift from the seventh to the first day of the week is justified by the resurrection of Christ and the new covenant fulfillment of the Sabbath rest in Christ. Sunday observance is not merely a cultural tradition but is rooted in the moral law of God and the reality that the resurrection inaugurates the new creation.

The CRCNA emphasizes Sunday as a day of corporate worship, spiritual renewal, and rest from ordinary labor. However, the specific practices — such as abstention from all forms of work or commerce — are not mandated by the CRCNA with the same strictness as Sabbatarian denominations. The focus is on the principle of dedicating time to God's worship and rest, informed by the biblical pattern and the church's tradition.
