The Seventh Day View is the view held by the Seventh Day Adventists, and the Seventh Day Baptists among others. This is the only consistent view, if the Sabbath was truly part of God's unchanging moral law for all people of all time. This view teaches that Saturday is the Sabbath, and that just as God introduced the Sabbath as a binding moral statute at creation, so it is still binding on all men today. It is to be observed by total rest (except for deeds of compassion and necessity). Further, this view teaches that it was included in the Ten Commandments, because the Ten Commandments are God's moral law for all people of all time.
The difficulty with this view is that it fails to take note of the fact that the Ten Commandments were the covenant document of the Old Covenant (Ex.34:28), and that the Old Covenant has become obsolete with the introduction of the New Covenant (Heb.8:13). Hebrews 7 argues that there has been a change in the priesthood. Christ is not of the priesthood of Aaron, but rather of the order of Melchizedek. "For when the priesthood is changed, of necessity there takes place a change of law also" (Heb.7:12). Now that the priesthood has been changed, a change in law has also taken place. We can't assume that something that was law under the Old Covenant is still law under the New Covenant. We must search the New Covenant document (the New Testament) to discover the binding imperatives upon believers. When we do so, we see that all the Biblical data teaches that the Sabbath was part of the Mosaic Law which has been fulfilled in Christ, and thus is no longer binding upon believers.
