les Frères en Christ observe Sunday (the Lord's Day) as the primary day of worship, following Christian tradition. Sunday commemorates Christ's la résurrection et est the day of Congrégationaliste gathering, prayer, et celebration.

Le Sabbath principle (a day of rest et holy time) est affirmé, but it est ne rigidly tied à Saturday or à Old Testament Sabbath laws. les Frères en Christ do ne enforce strict Sabbath observance (work prohibitions, travel restrictions, etc.) dans la manner of Seventh-day Adventists or orthodoxe Judaism.

Rather, the underlying principle—que Dieu sanctifies time, que rest et worship are important, que families should gather for fellowship—est affirmé. Individual believers may set aside time for rest et reflection, but this est ne mandated as la loi.
