The Ancient Church Kept Saturday
The Historians
Two fifth-century church historians, writing independently, recorded the same fact:
“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)
The global church kept Saturday. Rome was the exception.
The Ban
In 364 AD, the Council of Laodicea ordered Christians to stop resting on Saturday. The ban proves what it tried to prevent. If Saturday worship had ended naturally, no council over three hundred years after Christ would have needed to prohibit it.
The Survivors
The Ethiopian Orthodox Tewahedo Church, with over 36 million members, has kept Saturday as a sacred day alongside Sunday for more than 1,600 years. The monk Ewostatewos (c. 1273–1352) was flogged and exiled for defending this practice. His followers won at the Council of Mitmaq (1450). The Ethiopian canon includes the Book of Jubilees, which contains the oldest explicit statement that the Sabbath was observed in heaven before creation.
The Question
No New Testament verse commands Sunday worship. No ecumenical council authorized the change. The Roman Catholic Church openly claims the transfer as proof of its authority over Scripture. The Church Fathers record that the change was gradual, contested, and never accepted by the entire church.
The Sabbath was not lost; it was suppressed, and it survived.
