In the Christian era, the Sabbath has been a point of controversy since at least the fourth century AD, when the Roman Catholic Church assumed the authority to change the day of worship from the seventh day to the first. In the years that followed, thousands of seventh-day Sabbath-keepers were imprisoned or killed for obeying the fourth commandment.

When the Protestant Reformation took place centuries later, those opposed to the abuses and venality of the Catholic Church broke away in an attempt to set things straight. However, they continued to teach a number of corrupted doctrines, including the change to the Sabbath. Today, the vast majority of professing Christians hold the first day as the proper day of worship, even though the Bible is clear and consistent that only the seventh day was blessed, sanctified, and made holy (Genesis 2:3; Exodus 20:11).

Catholic theologians are unashamed of the change that their church made, readily admitting that if one goes by the Bible alone, the seventh day is still the Sabbath. For them, the matter comes down to church leadership having the authority to modify such things. Protestants, on the other hand, are unwilling to concede Papal authority. Instead, they justify Sunday-worship—a tradition of men—by saying they are honoring the day on which Christ rose from the dead.

Does this tradition have merit? It is certainly a widespread assumption, one that seems plausible on the surface and to which few give a second thought. Even so, there is no biblical record, implication, or hint of God removing the sanctification and holiness given to the seventh day and transferring it to another day.

Inherent within the assertion that the Sabbath has changed is the idea that the Creator Himself is changeable—that His standard of righteousness changes over time, and He is not serious about what He says. Yet, James 1:17 reminds us that with God "there is no variation or shadow of turning." He does not change—His fundamental character and approach to things are constant. Hebrews 13:8 says that Jesus Christ is "the same yesterday, today, and forever," and the next verse says, "Do not be led away by diverse and strange teachings" (ESV). God's changelessness is a major defense we have against false teaching. Thus, any doctrine that involves God backtracking on what He said—such as changing the Sabbath command—should be seen for what it truly is: an affront to His perfect, constant nature.

The Sabbath is neither a minor detail nor an obsolete ritual. It was the capstone of the creation week and is a creation of its own (Genesis 2:1-3). Humanity, created on the sixth day, is the pinnacle of God's physical creation, yet He created one more thing—the Sabbath—because physical man is incomplete. The physical creation is complete, yet there is a spiritual creation still taking place. God is creating mankind in His spiritual image (Genesis 1:26), and He has set apart—sanctified—the seventh day of each week to allow us to further this creation through fellowship with Him without being distracted by ordinary labors and pursuits. This does not mean we cannot fellowship with Him at other times—we can and should! But in setting aside the seventh day and making it holy, He has ensured that there will always be a space of time—a recurring memorial—to return our focus to the spiritual work God is doing.
