The question is not whether Orthodox Christians keep the Sabbath. The question is why the Western church stopped. Saturday worship persisted in the Eastern churches for centuries after Rome replaced it with Sunday. In some traditions, it never stopped.

Ethiopian Orthodox TewahedoSaturday Liturgy
The Ethiopian church numbers over 36 million members and has observed Saturday as a sacred day alongside Sunday for over 1,600 years. Their canon includes the Book of Jubilees, which contains the oldest explicit statement that the Sabbath was observed in heaven before creation.
“And the Creator of all things blessed this day which He had created for blessing and holiness and glory above all days.”
Jubilees 2:24 (R.H. Charles translation)
St. Ewostatewos (c. 1273–1352)Sabbath Defender
Ewostatewos was an Ethiopian monk who was flogged, exiled, and died in Armenia for defending Sabbath observance within the Ethiopian Orthodox Church. His followers, the Ewostatians, eventually prevailed at the Council of Mitmaq (1450), which restored Sabbath observance as official Ethiopian church practice.
He fought for truth within the Church, not against it, and he died faithful to the seventh day. His cause won after his death.
The author’s baptismal name, Eustathios, honors this saint.
The Greek Orthodox Church celebrates Great Vespers on Saturday evening, marking the beginning of the Lord’s Day. Saturday retains liturgical significance throughout the Orthodox calendar. Saturday is the day for commemorating the departed and is never a day of fasting (Canon 66 of the Apostolic Canons).
“If any clergyman be found fasting on a Sunday or on Saturday, except the one only Saturday before Easter, let him be deposed.”
The Russian Orthodox Church maintains the Saturday Vespers tradition and prohibits fasting on Saturdays (except Holy Saturday). The Typikon prescribes Saturday as a day of remembrance for the departed, with special memorial services (Panikhida) held on Soul Saturdays throughout the liturgical year.
Coptic Orthodox ChurchDual Observance
The Coptic Church of Egypt and the wider Oriental Orthodox family have historically observed both Saturday and Sunday as holy days. Socrates Scholasticus (fifth century) recorded that the churches in Egypt and the Thebaid assembled on Saturday for communion, a practice that persisted for centuries.
“For although almost all churches throughout the world celebrate the sacred mysteries on the sabbath of every week, yet the Christians of Alexandria and at Rome, on account of some ancient tradition, have ceased to do this.”
Socrates Scholasticus, Ecclesiastical History V.22 (c. 440 AD)
Armenian Apostolic ChurchHistorical Witness
The Armenian church preserved Saturday liturgical practices through centuries of isolation. Armenian Christians in the Caucasus maintained Sabbath observance alongside Sunday worship well into the medieval period.
The Historical Timeline
The Sabbath was not abandoned gradually. It was suppressed by specific decisions at specific dates.
c. 50 AD
The Didache
The oldest Christian catechism outside the New Testament describes worship practices without mentioning any transfer from Saturday to Sunday.
c. 100 AD
Apostolic Practice Continues
Acts records eighty-four Sabbaths observed by Paul. No New Testament text commands Sunday worship or transfers Sabbath sanctity to another day.
c. 150 AD
Justin Martyr’s Apology
Justin describes Sunday assemblies in Rome, but the broader church still assembles on Saturday. Dialogue with Trypho the Jew shows a Sabbath-keeping Christian would still be accepted.
321 AD
Constantine’s Sunday Law
Emperor Constantine decrees rest on “the venerable day of the sun.” This is a civil law, not a church council. Many Christians still observe Saturday.
364 AD
Council of Laodicea, Canon 29
Christians “must not Judaize by resting on the Sabbath, but must work on that day.” The very existence of this canon proves that Sabbath-keeping was still widespread enough to require a ban.
c. 380 AD
Apostolic Canons
Canon 64 (later numbered 66) prohibits clergy from fasting on Saturday, recognizing its continued sacred status in the Eastern church.
c. 440 AD
Socrates Scholasticus
The church historian records that “almost all churches throughout the world” still assemble on Saturday for communion. Only Rome and Alexandria had stopped.
c. 1300
Ewostatewos in Ethiopia
The Ethiopian monk defends Saturday observance within the Orthodox Church. He is flogged, exiled, and dies in Armenia. His followers continue his fight.
1450 AD
Council of Mitmaq
Nearly a century after Ewostatewos’s death, the Ethiopian Church officially restores Saturday as a day of rest and worship alongside Sunday. His cause prevails.
Today
36 Million Saturday Keepers
The Ethiopian Orthodox Tewahedo Church remains the largest body of Saturday-keeping Christians in the world. Their canon includes Jubilees, which teaches that the Sabbath was observed in heaven before creation.
The Council of Laodicea Proves the Sabbath Was Still Kept
Canon 29 of the Council of Laodicea (364 AD) ordered Christians to work on Saturday and rest on Sunday. This fact alone proves that, over three hundred years after Christ, enough Christians still kept the Sabbath to require an official ban.
If Saturday worship had ended naturally with the apostles, no council in 364 AD would have needed to prohibit it. The ban is the evidence.
The Parallel Innovation
Rome made two unilateral changes to the apostolic faith without the authority of an ecumenical council. The first was the filioque: adding “and the Son” to the Nicene Creed’s statement about the Holy Spirit. The second was the Sabbath change: transferring the day of rest from Saturday to Sunday.
Both changes follow the same pattern: each was made by one see (Rome) without the consent of the whole Church, and each is rejected by the Eastern churches. The Sabbath change happened first, in the fourth century, and the filioque was formally added in 1014 AD. Together they illustrate what happens when one bishop claims authority over all of Christendom.
The Orthodox Church preserved the original Creed. The Ethiopian Orthodox Church preserved the original day. The thread never broke.
