The Sabbath Question
The case for keeping the seventh day.
The Command
"Remember the sabbath day, to keep it holy. Six days shalt thou labour, and do all thy work: But the seventh day is the sabbath of the LORD thy God."
The Fourth Commandment doesn't say "a sabbath." It says "the sabbath," a specific day. It is not the first day but the seventh day.
The Biblical Week
Sunday = First day of the week
Saturday = Seventh day of the week
The biblical and Jewish weekly cycle identifies the seventh day with Saturday. The Gregorian reform of 1582 changed date labels while retaining the weekday sequence. The calendar study examines that evidence and the limits of broader continuity claims.
What Jesus Kept
"And he came to Nazareth, where he had been brought up: and, as his custom was, he went into the synagogue on the sabbath day."
Jesus kept the seventh-day Sabbath. It was His "custom," His regular practice. The Gospels contain no explicit command transferring it to Sunday. They also show Him defending hungry disciples and acts of mercy (Matthew 12:1–14). His Sabbath teaching must be read with those actions.
What the Apostles Kept
"And Paul, as his manner was, went in unto them, and three sabbath days reasoned with them out of the Scriptures."
Acts 17:1–9 places Paul in a Jewish synagogue, reasoning about Christ with Jews and devout Greeks. That setting is real Sabbath evidence. It does not by itself prescribe the worship calendar of every Gentile church.
The first-day evidence also matters: a gathering to break bread in Acts 20:7, regular setting aside for a collection in 1 Corinthians 16:1–4, and the risen Christ meeting His disciples in John 20:19–29. Sunday arguments draw these texts together. The passages do not expressly command a transfer of seventh-day holiness or describe a universal Sunday rest law.
Sunday Practice and Claims of Authority
Sunday assembly predates Laodicea. Justin, First Apology 67, describes readings, prayer, the Eucharist and help for the needy on Sunday, explaining the day by creation and Christ’s resurrection. Later Catholic writers defended Sunday through Christ-given Church authority. Their claims need to be read alongside that earlier evidence:
"The Catholic Church...by virtue of her divine mission, changed the day from Saturday to Sunday."
Catholic Mirror, September 23, 1893, conclusion, as reproduced in the Wikisource transcription of The Christian Sabbath.
“We observe Sunday instead of Saturday because the Catholic Church, in the Council of Laodicea (A. D. 336), transferred the solemnity from Saturday to Sunday.”
Peter Geiermann, The Convert’s Catechism of Catholic Doctrine, 2nd ed. (St. Louis: B. Herder, 1910), 50.
The manual’s date of 336 is unreliable; the council’s exact date is disputed. Geiermann’s following answers appeal to the Resurrection, Pentecost, and authority given by Christ. This is a catechist’s defense of Church authority, not an admission that the Church believed it was acting without divine authority.
What the Historian Recorded
Even in the fifth century, Socrates recorded widespread Sabbath celebration of the sacred mysteries, with Rome and Alexandria as 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), A. C. Zenos translation.
Socrates names Rome and Alexandria as exceptions while treating most other churches as Sabbath celebrants. In the same chapter he invokes Paul’s teaching about days and covenant liberty against imposing Jewish festival law on Christians. His report establishes widespread Sabbath assemblies; his own argument does not establish a universal rule of seventh-day rest.
The Question
Scripture commands the seventh day. The Apostolic Constitutions VII.23, a fourth-century church order, directs celebration of both the Sabbath and the Lord’s Day, associating them with creation and resurrection. That is evidence for both-day practice in its setting, not a text written by the apostles or proof that every church followed it.
The New Testament gives no explicit command transferring Sabbath holiness to Sunday. That does not settle every Christian objection. Some Christians read Romans 14:5–6 and Colossians 2:16–17 as freedom from a binding sacred day under the new covenant. On that reading, no transfer command is needed.
The seventh-day case presented here rests on God’s blessing at creation and the Fourth Commandment (Genesis 2:2–3; Exodus 20:8–11). It must also explain why that command remains binding under the new covenant and how Paul’s statements about days fit that conclusion. Appendix B examines that dispute.
If you keep the Sabbath, make room for worship, rest, prayer and care for others. Jesus’ defense of hungry disciples and doing good belongs at the center of practice. Plan ahead where you can; attend to real needs with mercy.
