Sabbath

Christian Churches teach that the Sabbath commandment was fulfilled in Christ and is not binding on New Covenant believers. The ceremonial law, including Sabbath observance, is no longer in force. However, the principle of weekly rest and gathered worship is affirmed, expressed through Sunday (the First Day, the Lord's Day) rather than Saturday (the Sabbath).

Sunday worship commemorates Christ's resurrection, which occurred on the first day of the week. The apostolic church gathered on Sunday for worship, teaching, breaking bread, and prayer (Acts 20:7; 1 Corinthians 16:2). This First Day worship pattern is normative for Christian assemblies, not as a strictly mandated commandment but as the apostolic practice.

There is no requirement of strict Sabbatarianism: believers may work on Sunday, conduct business, travel, and engage in ordinary activities without guilt or condemnation. Sunday is the day of gathered worship and rest, but its observance is a matter of Christian liberty rather than legal obligation. This reflects the Galatians principle: believers are not under law but under grace, yet respond to grace through willing obedience and love.
