Who Changed the Sabbath?

One of the most common assumptions in modern Christianity is that the seventh-day Sabbath was somehow “changed” by Yeshua (Jesus) or replaced by Sunday worship very early on. Yet when we examine Scripture closely—and then follow the historical trail—we discover a very different story.

The rejection of the biblical Sabbath did not begin with Yeshua, nor with His apostles. It unfolded gradually over several centuries, shaped more by cultural pressure and church politics than by Scripture itself.

Let’s take a little journey through the past and see just what happened.

Yeshua and the Apostles Did Not Abandon the Sabbath

The New Testament shows that Yeshua fully honored the seventh-day Sabbath—not as a burden, but as a gift.

“Now when he went to Natzeret, where he had been brought up, on Shabbat he went into the synagogue as usual.”
—Luke 4:16a

Yeshua never taught His disciples to stop keeping the Sabbath. Instead, He corrected man-made traditions that had distorted it (see Mark 7:8–13).

After Yeshua’s resurrection, His apostles continued this established practice:

“but the others went on from Perga to Pisidian Antioch, and on Shabbat they went into the synagogue and sat down.”
—Acts 13:14

“For Sha’ul, this was his custom: on Shabbat he would go in and argue with them from the Tanakh.”
—Acts 17:2

Scripture never records a command to abandon the seventh-day Sabbath or to replace it with a different day.

The First Shift: Separation from Jewish Identity (2nd Century)

The earliest move away from Sabbath observance did not come from theology—it came from identity politics.

After the destruction of Jerusalem in AD 70 and the Bar Kokhba revolt (AD 132–135), Roman hostility toward Jews intensified. Jewish (and Christian) customs—including Sabbath keeping—became socially and legally dangerous.

Due to antisemitism, “gentile believers” increasingly sought to distance themselves from anything that appeared “Jewish.”

But Remember: Yeshua, all of the apostles and nearly all of the early believers were in fact…Jews!

Early church writers began to emphasize Sunday gatherings—not because Scripture commanded it, but because it distinguished Christians from the very heritage of their Messiah.

One often-quoted example is Justin Martyr (c. AD 150), who described Christians meeting on “the day of the sun.”

In Chapter 67 of First Apology, he writes:

“And on the day called Sunday, all who live in cities or in the country gather together in one place…”
— First Apology 67

Note that he never claimed this replaced the Sabbath by God’s command—only that it was the church’s practice.

This marks the beginning of custom replacing scripture.

Constantine and the Legalization of Sunday (4th Century)

A major turning point came under Constantine.

In AD 321, Constantine issued a civil decree (commonly known as Constantine’s Sunday Law of 321 AD or the Sunday Edict of Constantine):

“On the venerable day of the Sun let the magistrates and people residing in cities rest…”

This was not a Christian theological statement. It was a Roman law influenced by sun-veneration culture and political unity. Farmers were explicitly exempt, underscoring its civic—not biblical—nature.

This is the first time Sunday rest appears as law, not doctrine.

Scripture, by contrast, defines the Sabbath clearly:

“The seventh day is Shabbat for ADONAI your God.”
—Exodus 20:10

The Council of Laodicea: A Formal Rejection of the Sabbath

Around AD 363–364, the Council of Laodicea issued a decisive ruling, taking this much further:

Canon 29:
“Christians must not judaize by resting on the Sabbath, but must work on that day, honoring instead the Lord’s Day…”

This is a crucial historical moment.

For the first time, resting on the seventh day was condemned, not merely ignored.

What did this Mean?

This was the first official church ruling that explicitly forbade Christians from keeping Shabbat.
Sabbath-keeping was labeled “Judaizing”—a theological crime.
While this canon imposed church discipline, not yet civil punishment, it laid the foundation of what would come in the future/

Late 4th–6th century — Church + State Merge

Under emperors like Theodosius I, “Christianity” became the state religion (380 AD).

From this point:

Church rulings increasingly carried civil consequences
So-called “heresy” could result in loss of rights, fines, exile, or worse

Sabbath-keeping Christians were often grouped with “Jews,” accused of rejecting church authority and targeted under “anti-Judaizing” laws.

Eventually the “Church” condemned:

Refusing the Church’s Sunday rest
Observing the biblical Sabbath – Saturday as sacred
Identifying with “Jewish” practice

Any of these could result in legal penalties, depending on the region.

In some areas, this included fines, loss of employment, being shunned or exiled, or charges of heresy (which could escalate severely!)

This terrible pattern continued through the Byzantine Empire, Medieval canon law and later European church-state systems.

What Does the Bible Say Was Supposed to Happen?

Rather than predicting the biblical Sabbath’s disappearance, the Scriptures warn that God’s commandments would be altered by human authority.

“He will speak words against the Most High and try to exhaust the holy ones of the Most High. He will attempt to alter the seasons and the law…”
—Daniel 7:25a

Meanwhile, the New Testament affirms that the Father’s Sabbath never ended:

“So then, there remains a Shabbat-keeping for God’s people.”
—Hebrews 4:9

To Review – A Gradual Drift, Not a Divine Command

As we saw:

Yeshua kept the Sabbath
The apostles kept the Sabbath
Scripture never changed the day
Sunday observance came on gradually
Legal enforcement came centuries later
The rejection of Sabbath was driven by anti-“Jewish” sentiment and Roman influence

This was not an act of obedience to Scripture—it was a departure from it.

The change from widespread Sabbath-keeping moving from the biblical seventh day to the man-made “first day” or “Lord’s Day” didn’t happen all at once. It was a slow creep down a dark path.

But What About the “Sunday verse” people point to?

One particular passage in Acts is often cited to backup the claim that the Sabbath changed in the New Testament—but it never teaches a Sabbath change.

“On the first day of the week, when we were gathered together to break bread, Paul talked with them, intending to depart on the next day, and he prolonged his speech until midnight.”
—Act 20:7 (ESV)

Many translations of the bible use the words “first day of the week” in this scripture, but when you look at what words were actually there – as seen in the CJB – the meaning is very different.

“On Motza’ei-Shabbat, when we were gathered to break bread, Sha’ul addressed them. Since he was going to leave the next day, he kept talking until midnight.”
—Acts 20:7

Motza’ei-Shabbat (מוֹצָאֵי שַׁבָּת) literally means “the going-out of the Sabbath.”
It refers to the time when Shabbat ends, not a separate day. It is the end of the day, at sunset. Saturday night. (See: When Does the Day Begin and End?)

When we look at this in context we see:

This was a farewell meeting, as Paul was about to embark on a trip
It happened at night – the biblical beginning of the next day
“Breaking bread” is not a new Sabbath command – they were just hungry and eating
No instruction, no theology, no repetition anywhere else to confirm this changes God’s Sabbath

All of this simply describes an event, not a new holy day.
