The C&MA teaches that the church's day of worship has shifted from the Jewish Sabbath (Saturday) to the Lord's Day (Sunday), in commemoration of Christ's resurrection. This is rooted in the New Testament practice of the apostolic church gathering on the first day of the week. The C&MA does not require Sabbath observance as a binding commandment for Christians, viewing the Sabbath command as part of the Mosaic covenant specific to Israel and fulfilled in Christ.

However, the C&MA affirms the principle underlying the Sabbath: the need for rest, worship, and renewal. Christians are called to set apart time for worship, prayer, and spiritual refreshment. Sunday is understood not merely as a day off but as a day sanctified to the Lord, to be used for corporate worship, spiritual growth, and rest from ordinary labor where possible. The C&MA encourages believers to use Sunday as a day of church attendance and spiritual focus.

The C&MA does not impose strict regulations on what may or may not be done on Sunday, nor does it require that believers observe the Sabbath. The focus is on the principle of regular worship and rest in Christ, not on legalistic rules. Individual Christians and congregations exercise wisdom and conscience in how they use the Lord's Day, guided by the desire to honor God and cultivate spiritual life.
