When did the church stop keeping Saturday?

The transition was gradual and varied by region. Emperor Constantine enacted a civil Sunday-rest law in 321 AD. The regional Council of Laodicea later addressed Christians who rested on Saturday, showing that the practice persisted in its jurisdiction. Eastern canons retained Saturday's liturgical distinction, while Ethiopian sources describe a later dispute and settlement concerning Saturday observance.

What did the Church Fathers say about Saturday worship?

Socrates Scholasticus and Sozomen report widespread Saturday assemblies in the fifth century while naming regional exceptions. The Apostolic Constitutions assign worship to both Saturday and Sunday. These texts establish substantial Saturday liturgical practice; they do not prove universal Sabbatarian rest or one unbroken institution.

Do Orthodox Christians Keep the Sabbath?

Q: What is the Council of Laodicea Canon 29?

Canon 29 of the regional Council of Laodicea ordered Christians not to 'Judaize by resting on the Sabbath' but to work that day and honor the Lord's Day. The prohibition shows that Sabbath rest remained a live concern within the council's jurisdiction. It does not measure the practice throughout the fourth-century church.

The short answer depends on what keep means. The Ethiopian Orthodox Tewahedo tradition treats Saturday as sacred alongside Sunday. Byzantine Orthodox practice preserves Saturday’s festal character through anti-fasting canons and appointed liturgies, but most Byzantine Orthodox Christians do not practice seventh-day Sabbatarian rest. The Council of Laodicea, often cited in this debate, was regional rather than ecumenical.

The Ethiopian Witness

Ethiopian sources preserve a substantial dual-observance tradition. In the fourteenth century, the monk Ewostatewos (c. 1273–1352) defended Saturday observance and suffered exile. His followers’ dispute with church authorities continued into the fifteenth century, when a settlement traditionally associated with the Council of Mitmaq in 1450 secured recognition for Saturday observance. This evidence establishes a durable Ethiopian tradition without proving that every Ethiopian Christian followed one uniform practice in every century.

The Ethiopian canon includes the Book of Jubilees, which places Sabbath holiness within its account of creation: “And the Creator of all things blessed this day which He had created for blessing and holiness and glory above all days” (Jubilees 2:32). Jubilees is evidence for an ancient Jewish interpretation; Christian traditions disagree about its canonical authority.

The Historical Record

Two fifth-century church historians described Saturday assemblies as widespread while naming regional exceptions:

“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)

“The people of Constantinople, and almost everywhere, assemble together on the Sabbath, as well as on the first day of the week, which custom is never observed at Rome or at Alexandria.”
Sozomen, Ecclesiastical History VII.19 (c. 450 AD)

Their testimony is strong evidence for broad fifth-century Saturday liturgical practice. It is not a census of every church, proof of universal Sabbath rest, or evidence of a single Sabbatarian institution.

The Council of Laodicea (364 AD)

Canon 29 of the regional Council of Laodicea directed Christians not to “Judaize by resting on the Sabbath,” but to work that day and honor the Lord’s Day. The prohibition shows that Sabbath rest remained a live concern within the council’s jurisdiction. It does not establish how common the practice was throughout the fourth-century church.

The Council in Trullo (692 AD)

Three centuries after Laodicea, the Council in Trullo (also called the Quinisext Council), Canon 55, condemned Rome’s practice of fasting on Saturdays during Lent: “Since we understand that in the city of Rome, they fast on the Saturdays of holy Lent, contrary to the traditional practice handed down to us, it has seemed good to the holy council that also in the church of Rome the canon shall immovably stand which says: If any clergyman is found to fast on Sunday or Saturday (except one only), he is to be deposed.” Trullo therefore protected Saturday’s festal character. The canon concerns fasting, however; it does not command seventh-day Sabbatarian rest.

The Great Schism (1054 AD)

Saturday fasting was one issue in the wider eleventh-century dispute between Greek and Latin Christians. Nicetas Stethatos, a monk of the Stoudios Monastery in Constantinople, wrote his Libellus Contra Latinos accusing Rome of breaking received rules by fasting on Saturday. This was an old East-West disciplinary controversy, not a debate in which the Byzantine churches adopted modern seventh-day Sabbatarianism.

Saturday in Orthodox Practice Today

Orthodox practice varies by jurisdiction, monastery, parish, calendar, and feast. Saturday liturgies occur in monastic life and on appointed parish occasions; Saturday also carries commemorations of saints and the departed. Received canons normally prohibit Saturday fasting, with Holy Saturday as the stated exception. Saturday evening Vespers belongs to the liturgical opening of Sunday, so it should not be counted by itself as evidence of Saturday Sabbath observance. The tradition preserves a distinct Saturday character while generally locating the principal weekly celebration on Sunday.
