1. The Sabbath is a “creation ordinance,” a weekly rest patterned after God’s creation rest, and established for mankind by God at the beginning of history. This is the teaching of Genesis 2:2–3 as interpreted by Exodus 20:10–11 and especially by Mark 2:27–28 and Hebrews 3:7–4:13.
2. The Sabbath was intended for all men from the beginning and is thus for all ages until the consummation of all things. Among others, Mark 2:27–28 particularly points to the inclusiveness of the Sabbath ordinance, and Hebrews 3:7–4:13 to the final goal of entering into God’s eternal rest that awaits those who persevere in faith.
3. The Sabbath is meant to be a day of rest from labor and a day of worship, holy to the Lord. It is defined in terms of rest, as in Exodus 20:10–11 and the activity of worship is not only appropriate to the sanctifying of the day commanded by God, but is prescribed as in Leviticus 23:3; cf. Acts 15:21.
4. The Sabbath received the same kind of attention from our Lord during his earthly ministry that was given to other commandments of God, as he purified it from “traditions of men,” brought it to perfected expression, and thus prepared it for his New Testament people. Jesus’ concern for the Sabbath is seen in such passages as Mark 2:27–28; 3:1–6; Luke 13:10–17; 14:1–6.
5. The Sabbath was not abrogated for the New Testament dispensation. Colossians 2:16–17 refers to the loosing of the bonds of the Mosaic requirements in respect to ceremonial and sacrificial elements of the Old Testament holy days in the light of Christ’s perfect sacrifice; but it does not remove the obligation of the Fourth Commandment itself. Such passages as Romans 14:5–6 and Galatians 4:10 do not nullify all distinctions between days, since the New Testament itself distinguishes the first day of the week from other days, as in 1 Corinthians 16:2; Acts 20:7, and designates that day as the Lord’s Day or Christian Sabbath, as in Revelation 1:10.
6. In summary: The Scriptures teach that God, by a positive, moral, and perpetual commandment, binding all men in all ages, has appointed one day in seven for a Sabbath, to be kept holy unto him.
