We believe and confess that the Lord’s Day is a Christian ordinance that must be kept continually, spent in worship and spiritual reflection, both in public and at home. Unlike the old Mosaic covenant, when the seventh day was observed, Christians, as members of the New Covenant, must observe the first day of the week [Sunday], which was sanctified by God through the resurrection of His Son from the dead and by the sending of the Holy Spirit.
The early Christians kept it as a day of worship. On this day, we should rest from worldly labors and physical distractions, engaging instead in acts of mercy and those things which are absolutely necessary.
We do not observe holidays dedicated to saints.
