Sunday in the First Centuries After Christ

By Robert K. Sanders


Seventh-day Adventists, Seventh Day Baptists, Church of God, Church of God 7th Day, and other sabbatarians claim that Christians must worship on Saturday, the Jewish Sabbath. They also claim that worshipping God on Sunday is honoring the sun god. Some Sabbatarians claim that the early Christians were following the Roman pagan practice of worshiping on Sunday in honor of the sun god. The fact is that the Romans did not have a weekly day set aside to worship the sun god. Jesus choose to rise from the grave on the first day of the week. Did Jesus honor the sun god?


Which Day is The Lord's Day?

The term "The Lord's Day" is used one time in the Bible:

Rev 1:10 (NIV) On the Lord’s Day I was in the Spirit, and I heard behind me a loud voice like a trumpet

Sabbatarians twist the Bible by saying that "the Lord's Day" is the Sabbath because Jesus said, he was Lord of the Sabbath.

Matt 12:8 (NIV) For the Son of Man is Lord of the Sabbath.

Never is the Sabbath called "the Lord's Day" in the Scriptures. The Sabbath is always called (in the Greek) Sabbaton or in the Hebrew Shabbath.

Strong's: G4521 σάββατον sabbaton sab'-bat-on Of Hebrew origin [H7676]; the Sabbath (that is, Shabbath), or day of weekly repose from secular avocations (also the observance or institution itself).

The quotations below show that the early Church Fathers met for worship on Sunday in the first century, long before the Roman Catholic Church was formed. These early church fathers were closest to the Apostles. The Apostles wanted to honor their Savior by having a day that Christ rose from the dead, set aside for worship. They were thrilled that Christ rose from the grave and that their salvation was assured.


1. The Didache [A.D. 70]

"But every Lord's day . . . gather yourselves together and break bread, and give thanksgiving after having confessed your transgressions, that your sacrifice may be pure. But let no one that is at variance with his fellow come together with you, until they be reconciled, that your sacrifice may not be profaned" (Didache 14 [A.D. 70]).


2. The Letter of Barnabas [A.D. 74]

"We keep the eighth day [Sunday] with joyfulness, the day also on which Jesus rose again from the dead" (Letter of Barnabas 15:6-8 [A.D. 74]).


3. Ignatius of Antioch" [A.D. 110]

[T]hose who were brought up in the ancient order of things [i.e. Jews] have come to the possession of a new hope, no longer observing the sabbath, but living in the observance of the Lord's day, on which also our life has sprung up again by him and by his death" (Letter to the Magnesians 8 [A.D. 110]).


4. Justin Martyr [A.D. 155]

"[W]e too would observe the fleshly circumcision, and the sabbaths, and in short all the feasts, if we did not know for what reason they were enjoined [on] you--namely, on account of your transgressions and the hardness of your heart. . . . [H]ow is it, Trypho, that we would not observe those rites which do not harm us--I speak of fleshly circumcision and sabbaths and feasts? . . . God enjoined you to keep the sabbath, and impose on you other precepts for a sign, as I have already said, on account of your unrighteousness and that of your fathers" (Dialogue with Trypho the Jew 18, 21 [A.D. 155]).


5. Tertullian [A.D. 203]

"[L]et him who contends that the sabbath is still to be observed as a balm of salvation, and circumcision on the eighth day . . . teach us that, for the time past, righteous men kept the sabbath or practiced circumcision, and were thus rendered 'friends of God.' For if circumcision purges a man, since God made Adam uncircumcised, why did he not circumcise him, even after his sinning, if circumcision purges? . . . Therefore, since God originated Adam uncircumcised and unobservant of the sabbath, consequently his offspring also, Abel, offering him sacrifices, uncircumcised and unobservant of the sabbath, was by him [God] commended [Gen. 4:1-7, Heb. 9:4]. . . . Noah also, uncircumcised--yes, and unobservant of the sabbath--God freed from the deluge. For Enoch too, most righteous man, uncircumcised and unobservant of the sabbath, he translated from this world, who did not first taste death in order that, being a candidate for eternal life, he might show us that we also may, without the burden of the law of Moses, please God" (An Answer to the Jews 2 [A.D. 203]).


6. The Didascalia [A.D. 225]

"The apostles further appointed: On the first day of the week let there be service, and the reading of the Holy Scriptures, and the oblation, because on the first day of the week our Lord rose from the place of the dead, and on the first day of the week he arose upon the world, and on the first day of the week he ascended up to heaven, and on the first day of the week he will appear at last with the angels of heaven" (Didascalia 2 [A.D. 225]).


7. Origen [A.D. 229]

"Hence it is not possible that the [day of] rest after the sabbath should have come into existence from the seventh [day] of our God. On the contrary, it is our Savior who, after the pattern of his own rest, caused us to be made in the likeness of his death, and hence also of his resurrection" (Commentary on John 2:28 [A.D. 229]).


8. Victorinus [A.D. 300]

"The sixth day [Friday] is called parasceve, that is to say, the preparation of the kingdom. . . . On this day also, on account of the passion of the Lord Jesus Christ, we make either a station to God or a fast. On the seventh day he rested from all his works, and blessed it, and sanctified it. On the former day we are accustomed to fast rigorously, that on the Lord's day we may go forth to our bread with giving of thanks. And let the parasceve become a rigorous fast, lest we should appear to observe any sabbath with the Jews . . . which sabbath he [Christ] in his body abolished" (The Creation of the World [A.D. 300]).]


9. Eusebius of Caesarea [A.D. 312]

"They [the early saints of the Old Testament] did not care about circumcision of the body, neither do we [Christians]. They did not care about observing sabbaths, nor do we. They did not avoid certain kinds of food, neither did they regard the other distinctions which Moses first delivered to their posterity to be observed as symbols; nor do Christians of the present day do such things" (Church History 1:4:8 [A.D. 312]).


10. Eusebius of Caesarea [A.D. 319]

"[T]he day of his [Christ's] light . . . was the day of his resurrection from the dead, which they say, as being the one and only truly holy day and the Lord's day, is better than any number of days as we ordinarily understand them, and better than the days set apart by the Mosaic Law for feasts, new moons, and sabbaths, which the Apostle [Paul] teaches are the shadow of days and not days in reality" (Proof of the Gospel 4:16:186 [A.D. 319]).


11. Athanasius [A.D. 345]

"The sabbath was the end of the first creation, the Lord's day was the beginning of the second, in which he renewed and restored the old in the same way as he prescribed that they should formerly observe the sabbath as a memorial of the end of the first things, so we honor the Lord's day as being the memorial of the new creation" (On Sabbath and Circumcision 3 [A.D. 345]).


12. Cyril of Jerusalem [A.D. 350]

"Fall not away either into the sect of the Samaritans or into Judaism, for Jesus Christ has henceforth ransomed you. Stand aloof from all observance of sabbaths and from calling any indifferent meats common or unclean" (Catechetical Lectures 4:37 [A.D. 350]).


13. Council of Laodicea [A.D. 360]

"Christians should not Judaize and should not be idle on the sabbath, but should work on that day; they should, however, particularly reverence the Lord's day and, if possible, not work on it, because they were Christians" (canon 29 [A.D. 360]).


14. John Chrysostom [A.D. 387]

"[W]hen he said, 'You shall not kill' . . . he did not add, 'because murder is a wicked thing.' The reason was that conscience had taught this before hand, and he speaks thus, as to those who know and understand the point. Wherefore when he speaks to us of another commandment, not known to us by the dictate of conscience, he not only prohibits, but adds the reason. When, for instance, he gave commandment concerning the sabbath--'On the seventh day you shall do no work'--he subjoined also the reason for this cessation. What was this? 'Because on the seventh day God rested from all his works which he had begun to make' [Ex. 20:10]. And again: 'Because you were a servant in the land of Egypt' [Deut. 21:18]. For what purpose then, I ask, did he add a reason respecting the sabbath, but did no such thing in regard to murder? Because this commandment was not one of the leading ones. It was not one of those which were accurately defined of our conscience, but a kind of partial and temporary one, and for this reason it was abolished afterward. But those which are necessary and uphold our life are the following: 'You shall not kill . . . You shall not commit adultery . . . You shall not steal.' On this account he adds no reason in this case, nor enters into any instruction on the matter, but is content with the bare prohibition" (Homilies on the Statues 12:9 [A.D. 387]).


15. John Chrysostom [A.D. 395]

"You have put on Christ, you have become a member of the Lord and been enrolled in the heavenly city, and you still grovel in the Law [of Moses]? How is it possible for you to obtain the kingdom? Listen to Paul's words, that the observance of the Law overthrows the gospel, and learn, if you will, how this comes to pass, and tremble, and shun this pitfall. Why do you keep the sabbath and fast with the Jews?" (Homilies on Galatians 2:17 [A.D. 395]).


16. The Apostolic Constitutions [A.D. 400]

"And on the day of our Lord's resurrection, which is the Lord's day, meet more diligently, sending praise to God that made the universe by Jesus, and sent him to us, and condescended to let him suffer, and raised him from the dead. Otherwise what apology will he make to God who does not assemble on that day . . . in which is performed the reading of the prophets, the preaching of the gospel, the oblation of the sacrifice, the gift of the holy food" (Apostolic Constitutions 2:7:60 [A.D. 400]).


17. John Chrysostom [A.D. 402]

"The rite of circumcision was venerable in the Jews' account, forasmuch as the Law itself gave way thereto, and the sabbath was less esteemed than circumcision. For that circumcision might be performed, the sabbath was broken; but that the sabbath might be kept, circumcision was never broken; and mark, I pray, the dispensation of God. This is found to be even more solemn that the s abbath, as not being omitted at certain times. When then it is done away, much more is the sabbath" (Homilies on Philippians 10 [A.D. 402]).


18. Augustine [A.D. 412]

"Well, now, I should like to be told what there is in these Ten Commandments, except the observance of the sabbath, which ought not to be kept by a Christian . . . Which of these commandments would anyone say that the Christian ought not to keep? It is possible to contend that it is not the Law which was written on those two tables that the apostle [Paul] describes as 'the letter that kills' [2 Cor. 3:6], but the law of circumcision and the other sacred rites which are now abolished" (The Spirit and the Letter 24 [A.D. 412]).



  • There is no Biblical or historical support that the seventh-day Sabbath was changed to Sunday or that Sunday is a holy day, and that it was changed by the Pope of Rome or the Catholic Church.
  • Under the New Covenant there is no command to keep the Sabbath and there are no weekly holy days. The Sabbath was never designated as a "day of worship" for Israel but a day of rest.
  • Christians are to find their Sabbath rest in Christ daily and not in a weekly ritual. Hebrews 4. If a church or denomination chooses to select a day or days of the week for organized church meetings this is in harmony with the Bible.
