Why We Keep Saturday Sabbath as Latter-day Saints

Home›Teachings›Saturday Sabbath

The question is not complicated to ask. It becomes complicated only when we realize how much depends on the answer.

Which day is the Sabbath? And where, if anywhere, was it changed?

For most of Christian history — and for most Latter-day Saint history — the answer has been assumed rather than examined. Sunday is the day we go to church. It has always been that way. That must mean something.

But the Restoration does not permit us to settle questions by assumption. Joseph Smith did not restore the gospel by asking what everyone already believed. He asked which of it, if any, was true.

So let us ask the question carefully — from scripture, from history, and from the prophetic record of the Restoration itself.

The Foundation That Was Never Moved

The Sabbath does not begin with Moses. It does not begin with Israel. It begins before sin enters the world, before covenant, before any nation exists.

Three things happen at creation that cannot be undone by silence: God rests on the seventh day. He blesses the seventh day. He sanctifies it — sets it apart as holy. This is not a Jewish institution. It is a creation ordinance, given before Abraham, before Moses, before Israel drew a single breath.

When the commandment is later given at Sinai, it does not introduce something new. It restores something ancient. The language of Exodus 20 points back deliberately — “For in six days the LORD made heaven and earth… and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.” The commandment reaches behind itself to creation as its own reason.

And it is not given casually. It is written by the finger of God (Exodus 31:18). Not recorded by a scribe — written by God Himself, and placed inside the ark of the covenant. Early Latter-day Saint leaders understood this clearly. Joseph Fielding Smith taught:

The seventh day is the only day ever sanctified at creation, ever written by the finger of God, ever declared a perpetual covenant (Exodus 31:16–17). The question is not whether it was established. The question is whether it was ever changed — and by whose authority.

What Scripture Actually Records

If the Sabbath was changed, the change must be in the New Testament. That is where we should expect to find it. So we look carefully.

Yeshua’s custom was Sabbath observance. He corrected the man-made traditions that had been layered on top of it — the burdens added by tradition, not commanded by God — but He never challenged the day itself. His direct words are unambiguous:

The Sabbath is not a jot or a tittle. It is a commandment written in stone. The apostolic record after the resurrection shows the same pattern:

• Acts 13:42–44 Jews and Gentiles together gather on the Sabbath to hear Paul teach. It is not a Jewish-only accommodation; the Gentiles are explicitly included and ask Paul to return the following Sabbath.
• Acts 17:2 “And Paul, as his manner was, went in unto them, and three sabbath days reasoned with them out of the scriptures.” His custom mirrors his master’s.
• Acts 18:4 “And he reasoned in the synagogue every sabbath, and persuaded the Jews and the Greeks.”

What is absent from all of this is equally important.

The Earliest Voices After the Apostles

If the Sabbath had truly been changed by Yeshua or His apostles, the writers closest in time to them should speak clearly about that command. What we actually find is something different.

Ignatius of Antioch (early 2nd century) writes of believers no longer “living according to the Sabbath,” but he does not cite a command from Yeshua establishing a new holy day. His language reflects a shift in practice, not a recorded revelation redefining the commandment.

Justin Martyr (mid-2nd century) gives one of the earliest detailed descriptions of Sunday gatherings:

But even here, Justin does not claim that the fourth commandment was changed, that Sunday replaced the Sabbath by divine decree, or that the seventh day was no longer holy. He offers a theological explanation tied to creation and resurrection — not a command. What is most striking about these early writers is not what they say. It is what they do not say. None of them state that Christ changed the Sabbath to the first day. None claim the apostles redefined the fourth commandment. If such a foundational change had been made by divine authority, we would expect it stated clearly — not inferred across decades.

The Historical Record Fills the Gap

What scripture leaves unstated, history documents plainly. The transition from seventh-day to first-day observance develops gradually — and its mechanisms are civic and ecclesiastical, not revelatory.

• A.D. 321 — Constantine’s Edict The Roman Emperor issued the first civil law enforcing rest on “the venerable day of the sun.” This is a state document. It names the day by its pagan designation.
• 4th Century — Council of Laodicea The council explicitly forbade Sabbath observance and commanded Christians to work on Saturday and honor Sunday instead. The language is prohibition, not fulfillment.
• Later Ecclesiastical Acknowledgment Authorities in later centuries openly admitted the change was made by church authority, not by scriptural command. The Catholic Encyclopedia states plainly that the authority for the change rests with the church, not with scripture.

These developments occur well after the apostolic period — in exactly the timeframe the Restoration identifies as the era of doctrinal corruption and loss of original practices.

The Torah’s Own Test for Change

The question is not simply whether a change happened. Torah itself provides the standard by which any such change must be evaluated.

The commandments are not open to revision by later authority. Deuteronomy 13 goes further — anticipating exactly the kind of challenge Israel would face from those who claimed divine authority while directing the people away from God’s commands:

The test is not miracles. The test is not authority claims. The test is whether the commandment itself is altered. Even a prophet — even one who works signs — cannot alter what God has established. By Torah’s own standard, where no clear command, no recorded revelation, and no prophetic declaration in scripture authorizes a change — the commandment stands as given.

What Early Restoration Leaders Taught

One of the most consistent teachings of the early Restoration is that truth is not determined by tradition, longevity, or majority acceptance. It is determined by what God has revealed — and what He has not.

Sunday observance is undeniably old — but the question is whether it comes from God, or from tradition. Brigham Young was equally direct about the scope of what was lost:

The Restoration was not a minor correction. It was a declaration that foundational things had been lost or altered. Orson Pratt pressed the same principle directly:

That statement aligns directly with 1 Nephi 13. It frames the issue plainly: if something once established by God appears to be missing, altered, or obscured in later practice, the Restoration does not ask us to defend the tradition — it asks us to recover the original.

The Prophet’s Own Standard

The Restoration does not begin with tradition. It begins with a question. Joseph Smith did not ask, “What does everyone believe?” He asked, “Which of all these is right?”

Not a reform. A reset. And Joseph taught plainly what must follow:

We are open to truth — but we are not bound to inherited assumptions that lack revelation. The standard is not tradition. The standard is revelation. So we return to the question, not emotionally but honestly: where is the revelation that changes the Sabbath? Where is the command that redefines the fourth commandment? Where is the moment in scripture where God calls a different day holy?

Because Joseph’s entire mission rested on this: if something was changed without revelation, it must be restored.

Three Witnesses

If a doctrine is true, it should stand across all dispensations. What do the three witnesses say about the Sabbath?

Witness	What It Records	Verdict
Torah	Seventh day sanctified at creation (Gen 2:2–3). Written by the finger of God (Ex 31:18). Declared a perpetual covenant (Ex 31:16–17). Never redefined in scripture.	Seventh day. Sanctified. Unchanged.
Yeshua & Apostles	Yeshua’s custom was Sabbath observance (Luke 4:16). He came not to destroy the law (Matt 5:17). Apostles taught on the Sabbath to Jews and Gentiles (Acts 13, 17, 18). No apostolic declaration redefines the fourth commandment.	Continued. Observed. Never redefined.
The Restoration	Plain and precious truths were lost (1 Nephi 13). All creeds were wrong (JS–H 1:19). Truth is not determined by tradition but by revelation (BY). The standard is scripture, not church authority (Orson Pratt).	Tradition must be questioned. Revelation is the only standard.

If all three witnesses align on the seventh day — and none of them records the command that changed it — then the question becomes unavoidable: where did the change happen?
