The Sabbath, the Festivals, and the Selective Hermeneutics of Adventist Theology

By Sidney Davis | AskTheTeacher.blog

I. Introduction: The Creation-Based Argument for Sabbath

Seventh-day Adventists are among the strongest modern advocates for Sabbath observance. Central to their theology is the claim that the Sabbath is not merely a part of the Sinaitic covenant, but a universal moral obligation rooted in creation itself. They cite Genesis 2:2–3 as proof that God sanctified the seventh day from the beginning, thus making it binding on all humanity, not just Israel.

“And God blessed the seventh day and sanctified it, because on it He rested from all His work which God had created and made.” (Genesis 2:3)

However, this line of reasoning raises a serious question of theological consistency.

II. The Overlooked Creation Text: Genesis 1:14

Just one chapter earlier, the Torah establishes the mo’adim, or appointed times, at creation:

“And God said, ‘Let there be lights in the expanse of the heavens to separate the day from the night. And let them be for signs (otot) and for seasons (mo’adim), and for days and years.’” (Genesis 1:14)

The term mo’adim (מוֹעֲדִים) is the same word later used in Leviticus 23:2 to describe the festivals of the Lord:

“These are the mo’adim of the Lord, holy convocations, which you shall proclaim at their appointed times.”

This includes: Passover, Unleavened Bread, Firstfruits, Pentecost, Trumpets, Day of Atonement, and Tabernacles.

Genesis 1:14

God said, “Let there be lights in the expanse of the sky to separate day from night; they shall serve as signs for the set times—the days and the years;

וַיֹּ֣אמֶר אֱלֹהִ֗ים יְהִ֤י מְאֹרֹת֙ בִּרְקִ֣יעַ הַשָּׁמַ֔יִם לְהַבְדִּ֕יל בֵּ֥ין הַיּ֖וֹם וּבֵ֣ין הַלָּ֑יְלָה וְהָי֤וּ לְאֹתֹת֙ וּלְמ֣וֹעֲדִ֔ים וּלְיָמִ֖ים וְשָׁנִֽים׃

And G-d said: Let there be [suspended] luminaries in the firmament of the heaven [(The luminaries, like all things pertaining to heaven and to earth, had been created on the first day, but each of the particular creations was activated on its particular day.)] to divide between the day and the night, [after the first light had been secreted for the righteous for the world to come.] And let them serve for signs [(eclipses being omens of ill)], and for festivals, [reckoned by the New Moon], and for days, [the sun and the moon serving for half a day respectively], and for years, [completing their course through the zodiac in 365 days]. – The Rashi chumash by Rabbi Shraga Silverstein

Rashi – and for appointed seasons: This refers to the future, when the Israelites are destined to be commanded concerning the festivals and they [the festivals] are reckoned from the first phase of the moon. — [from Gen. Rabbah 6:1].

ולמועדים AND FOR SEASONS (FESTIVALS) — This is written with a view to the future when Israel would receive command regarding the festivals which would be calculated from the time of the lunar conjunction (Genesis Rabbah 6:1).

Question: If the Sabbath is binding on all humanity because it is rooted in creation, then why are the festivals not equally binding, since mo’adim were also established at creation?

III. Selective Theology and Inconsistent Application

Adventist theology claims that the Sabbath is a moral law because it predates Sinai and was “written in stone.” Yet they dismiss the festivals, which also predate Sinai (Gen 1:14) and are tied to the same covenantal framework in Leviticus 23. In fact, the weekly Sabbath is the first festival listed in that very chapter.

This inconsistency undermines their claim that Sabbath observance is based on creation and moral law. If we accept Genesis 1:14 as establishing a creation pattern of worship, then both the Sabbath and the festivals must be acknowledged.

To accept one and reject the other is to practice a selective hermeneutic—affirming what fits a theological system while ignoring what contradicts it.

IV. Covenant, Not Creation, as the True Basis

The Torah itself clarifies the purpose and audience of the Sabbath:

“It is a sign between Me and the children of Israel forever; for in six days the Lord made the heavens and the earth, and on the seventh day He rested and was refreshed.” (Exodus 31:17)

The Sabbath is a covenantal sign, not a universal moral command. It is a gift to Israel as part of her national identity and relationship with God.

“Moreover, I gave them My Sabbaths, to be a sign between Me and them, that they might know that I am the Lord who sanctifies them.” (Ezekiel 20:12)

If the Sabbath were a moral law for all humanity, it would not be described as a sign uniquely between God and Israel.

V. Conclusion: Covenant Consistency Requires Theological Integrity

To argue that the Sabbath is a moral obligation based on creation, while dismissing the festivals that share the same creation origin (mo’adim), reveals a selective theological method.

Only one of two conclusions can be drawn:
1. Both the Sabbath and festivals are covenantal obligations for Israel alone, not moral laws binding on all nations.
2. Or both are universal obligations, which would demand the full observance of all appointed times—not just the Sabbath.

To affirm the first is to uphold the integrity of Torah theology. To affirm the second is to embrace the full weight of Israel’s covenantal calendar.

But to affirm one and reject the other is to undermine the very foundation of the Sabbath argument itself.

VI. Isaiah 66:23 and the Selective Theology of Sabbath Continuity

Seventh-day Adventist theology frequently cites Isaiah 66:23 as evidence that Sabbath observance is not only eternal but universal—extending into the new heavens and the new earth:

“And it shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, saith the LORD.” (Isaiah 66:23)

This verse is employed to demonstrate that even in the eschatological future, Sabbath observance remains intact. Therefore, the argument goes, it must be binding for all believers today.

But this interpretation selectively emphasizes the Sabbath, while ignoring the new moon—which is mentioned with equal prominence in the same verse.

Hermeneutical Inconsistency

If Isaiah 66:23 proves the eternal observance of the Sabbath, then it equally proves the eternal observance of the New Moon:
– Both appear in parallel.
– Both are part of the worship rhythm in the renewed creation.
– Both are said to involve “all flesh”—implying universality.

Yet Adventists do not advocate or practice the New Moon observance today. Nor do they teach that Christians are obligated to keep the new moons as part of their worship calendar.

This reveals a hermeneutical inconsistency:

Why treat the Sabbath as permanently binding based on Isaiah 66:23, while completely disregarding the New Moon mentioned in the same breath?

The New Moon in Torah and Prophets

The New Moon (*Rosh Chodesh*) was not merely a calendrical marker; it was a sacred occasion:

– Numbers 10:10 – Trumpets were blown on the New Moon as a memorial before God.
– Numbers 28:11–15 – Sacrifices were required at every New Moon.
– 1 Samuel 20:5, 18 – New Moon was observed with feasts and rituals.
– Ezekiel 46:1, 3, 6 – In the vision of the future Temple, worship is observed on Sabbaths and New Moons.

If Adventists are willing to use Ezekiel 46 and Isaiah 66 to argue for Sabbath permanence, they must equally accept the New Moon as part of eschatological worship—or admit to a selective use of Scripture.

Conclusion: Be Consistent or Be Covenantally Honest

The use of Isaiah 66:23 to enforce Sabbath observance upon all Christians while ignoring the New Moon is theologically inconsistent and selective.

If this verse is to be taken as proof of eternal obligations in the new heavens and earth, it must be applied in full, not in part.

Thus, Adventists are left with two options:
1. Embrace both the Sabbath and New Moon as binding elements of eschatological and present worship, or
2. Recognize that both are covenantal features of Israel’s worship calendar, not universal moral laws.

Either way, to elevate the Sabbath while silencing the New Moon—especially when both are treated equally in Isaiah 66:23—is to cherry-pick theology.
