There are some in our day who suggest that Sunday worship is something that was entirely unknown among Christians until the time of Emperor Constantine (272 – 337 AD), and make the claim that its religious roots are entirely pagan. However, in celebration of Christ’s resurrection, the early Church moved the Sabbath from Saturday to Sunday (the first day of the week), calling it “the Lord’s day.” Here are some quotations from the early Church:
The Didache – “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 [approx. A.D. 70])
The Letter of Barnabas – “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])
Ignatius of Antioch – “Those 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])
Justin Martyr – “But Sunday is the day on which we all hold our common assembly, because it is the first day on which God, having wrought a change in the darkness and matter, made the world; and Jesus Christ our Savior on the same day rose from the dead.” (First Apology 67 [A.D. 155])
The Didascalia – “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 [i.e., Sunday] 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])
Athanasius – “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])
“Never be absent from God’s house on Sundays, without good reason,—never to miss the Lord’s Supper when administered in our own congregation,—never to let our place be empty when means of grace are going on, this is one way to be a growing and prosperous Christian. The very sermon that we needlessly miss, may contain a precious word in season for our souls. The very assembly for prayer and praise from which we stay away, may be the very gathering that would have cheered, and established, and quickened our hearts.” – J. C. Ryle
