Introduction
Many Sabbatarian groups today claim to be the “true Church” established by Jesus Christ because they observe the seventh-day Sabbath. Among them is the so-called “Jerusalem Church of God 7th Day Sabbath,” a branch connected historically with the broader Church of God (Seventh Day) movement.
Some members claim:
- They preserved the original faith of the apostles.
- The Catholic Church allegedly “changed” the Sabbath.
- Their movement is the continuation of the Jerusalem church founded by Christ.
- They alone restored biblical Christianity.
But do these claims stand up historically, biblically, and doctrinally?
The evidence says no.
1. Who Founded the Jerusalem Church of God 7th Day?
Historically, the movement traces its roots not to the apostles, but to the 19th-century Sabbatarian Adventist movement in America. Scholars and Church of God historical records themselves acknowledge this.
The broader Church of God (Seventh Day) emerged in the 1850s among Adventists who separated from early Seventh-day Adventists. One of the key figures identified in their history is Gilbert Cranmer, a former Adventist minister in Michigan. Later, Andrew N. Dugger became one of the most influential leaders. According to the Jerusalem branch’s own history, Dugger established a headquarters in Jerusalem in 1931.Thus:
- Jesus did not found the modern Jerusalem Church of God 7th Day organization.
- The apostles did not establish it as an institution.
- Historically, it arose in the United States nearly 1,800 years after Christ.
Even their own historical records acknowledge this timeline.
2. The Fatal Historical Problem with Their Claim
If they claim to be the original Church founded by Christ, historians would expect:
- continuous historical existence,
- identifiable bishops or leaders,
- preserved apostolic succession,
- documented sacramental continuity,
- historical presence across centuries.
But none of these exist for the Jerusalem Church of God 7th Day.
Instead, the movement emerged from:
- Millerite Adventism,
- Sabbatarian revivalism,
- 19th-century American restorationism.
This creates a massive historical gap between the apostles and the denomination.
By contrast, the Catholic Church possesses:
- documented episcopal succession from the apostles,
- continuous sacramental life,
- councils and creeds from antiquity,
- writings of early Church Fathers,
- uninterrupted historical continuity from the first century.
This is exactly what Christ promised:
“The gates of Hades shall not prevail against it” (Matthew 16:18).
If Christ’s Church disappeared for 1,800 years and needed restoration in the 1800s, then Christ’s promise failed.
But Christ cannot fail.
3. Did the Early Christians Keep Saturday Sabbath as an Obligation?
This is one of the central arguments of Sabbatarian groups.
However, the evidence from the New Testament and early Christianity shows that Christians gathered on Sunday, the Lord’s Day, because of Christ’s resurrection.
Biblical Evidence
The Resurrection Happened on Sunday
Christ rose “on the first day of the week” (Mark 16:2).
Christians Gathered on Sunday
“On the first day of the week, when we were gathered together to break bread…” (Acts 20:7)
This passage clearly describes Eucharistic worship on Sunday.
Collections Were Taken on Sunday
“On the first day of every week…” (1 Corinthians 16:2)
The “Lord’s Day”
“I was in the Spirit on the Lord’s Day” (Revelation 1:10)
From the earliest centuries, Christians universally understood this as Sunday.
4. What Did the Early Church Fathers Teach?
The historical evidence overwhelmingly contradicts modern Sabbatarian claims.
Ignatius of Antioch (c. AD 107)
He wrote:
“No longer observing the Sabbath, but living in observance of the Lord’s Day.”¹
This is devastating for Sabbatarian restorationist claims because Ignatius was taught by apostolic men.
Justin Martyr (c. AD 155)
Justin described Christian worship:
“On the day called Sunday, all who live in cities or in the country gather together…”²
He then explains that Christians worship on Sunday because Jesus rose from the dead on that day.
This is more than 1,600 years before modern Sabbatarian sects emerged.
Irenaeus of Lyons
Irenaeus emphasized apostolic succession and continuity through bishops tracing back to the apostles.³
This is precisely what restorationist groups lack.
5. Did the Catholic Church “Change the Sabbath”?
This is a common SDA and Sabbatarian accusation.
But historically, Christians were already worshiping on Sunday long before Constantine and centuries before the medieval Church.
The Church did not “change” the Sabbath in the sense critics claim.
Rather:
- the Mosaic ceremonial covenant reached fulfillment in Christ,
- Christians celebrated the new creation through the Resurrection,
- Sunday became the Lord’s Day of Christian worship.
The Catechism explains:
“Sunday is expressly distinguished from the Sabbath.”⁴
The Church teaches that the moral principle of worship remains, but Christians celebrate the fulfillment of the Old Covenant in Christ.
6. The Problem with Restorationism
Groups like:
- SDA,
- Church of God (7th Day),
- Jerusalem Church of God,
- Armstrongite movements,
often assume that Christianity became corrupted shortly after the apostles and had to be “restored.”
But this idea creates serious theological problems.
If the Church Fell Completely:
Then:
- Christ failed to preserve His Church.
- The Holy Spirit failed to guide believers.
- Christianity disappeared for centuries.
- No true Church existed until modern America.
This contradicts Scripture.
Jesus promised:
“I am with you always, to the end of the age” (Matthew 28:20).
7. Apostolic Succession: The Missing Link
The early Church understood authority through apostolic succession.
Clement of Rome taught:
“The apostles appointed bishops and deacons.”⁵
Irenaeus of Lyons wrote:
“We can enumerate those who were appointed bishops by the apostles.”⁶
The Catholic Church can trace this succession historically.
The Jerusalem Church of God 7th Day cannot.
Their authority depends largely on:
- private interpretation,
- restorationist assumptions,
- modern doctrinal reconstruction.
8. What About the Name “Church of God”?
Some Sabbatarian groups argue that because “Church of God” appears in Scripture, their denomination must be the true Church.
But this argument fails logically.
The Bible also uses:
- “Churches of Christ” (Romans 16:16),
- “the Way” (Acts 9:2),
- “body of Christ” (1 Corinthians 12:27),
- “assembly” or “ekklesia.”
These were descriptive terms, not exclusive denominational trademarks.
Having a biblical-sounding name does not prove apostolic authenticity.
9. Catholic Response to SDA and Sabbatarian Objections
Objection: “The true church must keep Saturday Sabbath.”
Response:
The apostles themselves worshiped on Sunday in honor of the Resurrection.
The earliest Christians universally testify to Sunday worship.
Objection: “The Catholic Church corrupted Christianity.”
Response:
Historical evidence shows continuity in doctrine, sacraments, episcopal leadership, and liturgy from the apostolic age onward.
The burden of proof lies on restorationist groups to explain:
- where their church existed before the 1800s,
- who their bishops were,
- where their sacraments were preserved,
- and why no early Christian sources describe their theology.
Objection: “The Catholic Church is pagan because of Sunday worship.”
Response:
Sunday worship predates Constantine and medieval Catholicism by centuries.
The Church Fathers testify clearly to this.
10. The Biblical Pattern of the True Church
The true Church established by Christ possesses:
Unity
“One body and one Spirit” (Ephesians 4:4)
Apostolic Authority
“He who hears you hears Me” (Luke 10:16)
Sacramental Life
Acts 2:42 describes:
- apostolic teaching,
- fellowship,
- breaking of bread,
- prayers.
Historical Continuity
The Church must exist continuously through history—not disappear and later reappear in America.
Conclusion
The historical evidence does not support the claim that the Jerusalem Church of God 7th Day is the original Church founded by Jesus Christ.
Instead, the evidence shows:
- it arose from the 19th-century Adventist movement,
- its Jerusalem headquarters was established only in 1931,
- it lacks apostolic succession,
- it cannot demonstrate continuous historical existence from the apostles,
- and its Sabbatarian theology conflicts with early Christian practice.
Meanwhile, the Catholic Church alone can historically demonstrate:
- continuous apostolic succession,
- sacramental continuity,
- documented existence since the first century,
- and fidelity to the faith handed down by the apostles.
The question is not merely who uses biblical terminology or keeps Saturday worship.
The real question is:
Which Church can historically trace itself back continuously to the apostles?
The historical evidence strongly points to the Catholic Church.
