es, John, in Revelation, was in the Spirit on Sunday, which was translated as "The Lord's Day" 3 centuries later, sometime after the Council of Nicaea, sometime after 325AD. It was one of the last books canonized in the Holy Bible by what would be called, "The Catholic Church".
The word "κυριακῇ" means Sunday, but nowhere in the Greek meaning is it rendered to mean "The Lords Day". This Translation was given after the reign of Constantine and an Edict of the Council of Nicaea concerning the rejection of God's 7th Day Sabbath along with His Judgments and Feasts and other commandments as well.
Incorrect-
"John, in Revelation, was in the Spirit on Sunday, which was translated as 'The Lord's Day' 3 centuries later..."
Correct Part:
The phrase “The Lord's Day” appears in Revelation 1:10, where John states: *“I was in the Spirit on the Lord's Day” (ἐν τῇ κυριακῇ ἡμέρᾳ, en tē kyriakē hēmera). The word "κυριακῇ" (kyriakē) is an adjective meaning "belonging to the Lord" or "of the Lord."
Incorrect Part:
The idea that this phrase was only translated as
"The Lord's Day" three centuries later is inaccurate.
The Greek term κυριακῇ was already understood by the early church to refer to Sunday-the first day of the week-
long before Constantine or the Council of Nicaea. For example:
Ignatius of Antioch (c. 107 AD) wrote: “Let every friend of Christ keep the Lord's Day as a festival, the resurrection day, the queen and chief of all the days” (Letter to the Magnesians 9:1).
This shows that the term “Lord’s Day” as referring to Sunday (the day of Jesus’ resurrection) was recognized by Christians well before 325 AD.
2. "It was one of the last books canonized in the Holy Bible by what would be called, 'The Catholic Church'."
Partially Correct:
Revelation was one of the more debated books in the early church due to its apocalyptic nature and symbolic language. However:
By the late 2nd century, key church fathers such as Irenaeus accepted Revelation as canonical.
The Council of Carthage (397 AD) formally listed Revelation as part of the New Testament canon, but the decision reflected earlier widespread acceptance in the church.
3. "The word 'κυριακῇ' means Sunday, but nowhere in the Greek meaning is it rendered to mean 'The Lord's Day'."
Incorrect:
The word κυριακῇ literally means "of the Lord" or "belonging to the Lord." In the context of Revelation 1:10, early Christians interpreted it as referring to Sunday, the day commemorating Jesus’ resurrection.
The Greek Septuagint and early Christian writings do not use κυριακῇ to refer to the Sabbath (Saturday).
By the 2nd century, Christians widely celebrated Sunday as the “Lord’s Day,” separate from the Jewish Sabbath.
Incorrect:
There was no edict at the Council of Nicaea concerning the Sabbath or Sunday worship.
Sunday worship was already well-established among Christians by the
2nd century, as seen in Acts 20:7 (“On the first day of the week we came together to break bread”) and 1 Corinthians 16:2 (“On the first day of every week, each one of you should set aside a sum of money...”).
The Council of Nicaea (325 AD) primarily addressed Christological issues, such as the deity of Christ, and did not legislate Sabbath observance.
5. "Concerning the rejection of God's 7th Day Sabbath along with His Judgments and Feasts and other commandments as well."
Incorrect/Exaggerated:
The shift from Sabbath (Saturday) observance to Sunday worship did not result from a formal rejection of the Sabbath or other biblical commandments but reflected the early church’s emphasis on the resurrection of Jesus.
Christians from the 1st century onward celebrated Sunday as the day of worship because it was the day Jesus rose from the dead (Mark 16:1-2, John 20:1).
The Jerusalem Council (Acts 15) determined that Gentile Christians were not bound by Jewish ceremonial laws (including feasts) but focused on faith in Christ.
The following quotations show that the first Christians understood that Sunday became the Lord’s Day as a result of Christ’s resurrection, and therefore replaced the Sabbath. This is why believers gathered for worship on first day of the week.
The Didache
Chapter 14. Christian Assembly on the Lord’s Day
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. For this is that which was spoken by the Lord: In every place and time offer to me a pure sacrifice; for I am a great King, says the Lord, and my name is wonderful among the nations. (The Didache [A.D. 70]).
Epistle of Barnabas
Chapter 15. The false and the true Sabbath
Further, also, it is written concerning the Sabbath in the Decalogue which [the Lord] spoke, face to face, to Moses on Mount Sinai, And sanctify the Sabbath of the Lord with clean hands and a pure heart. Exodus 20:8; Deuteronomy 5:12 And He says in another place, If my sons keep the Sabbath, then will I cause my mercy to rest upon them. Jeremiah 17:24-25 The Sabbath is mentioned at the beginning of the creation [thus]: And God made in six days the works of His hands, and made an end on the seventh day, and rested on it, and sanctified it. Attend, my children, to the meaning of this expression, He finished in six days. This implies that the Lord will finish all things in six thousand years, for a day is with Him a thousand years. And He Himself testifies, saying, Behold, today will be as a thousand years. Therefore, my children, in six days, that is, in six thousand years, all things will be finished. And He rested on the seventh day. This means: when His Son, coming [again], shall destroy the time of the wicked man, and judge the ungodly, and change the-sun, and the moon, and the stars, then shall He truly rest on the seventh day. Moreover, He says, You shall sanctify it with pure hands and a pure heart. If, therefore, any one can now sanctify the day which God has sanctified, except he is pure in heart in all things, we are deceived. Behold, therefore: certainly then one properly resting sanctifies it, when we ourselves, having received the promise, wickedness no longer existing, and all things having been made new by the Lord, shall be able to work righteousness. Then we shall be able to sanctify it, having been first sanctified ourselves. Further, He says to them, Your new moons and your Sabbath I cannot endure. Isaiah 1:13 You perceive how He speaks: Your present Sabbaths are not acceptable to Me, but that is which I have made, [namely this,] when, giving rest to all things, I shall make a beginning of the eighth day, that is, a beginning of another world. Wherefore, also, we keep the eighth day with joyfulness, the day also on which Jesus rose again from the dead. And when He had manifested Himself, He ascended into the heavens. (Ibid. [A.D. 74])
Ignatius of Antioch
Chapter 8. Caution against false doctrines
Be not deceived with strange doctrines, nor with old fables, which are unprofitable. For if we still live according to the Jewish law, we acknowledge that we have not received grace. For the divinest prophets lived according to Christ Jesus. On this account also they were persecuted, being inspired by His grace to fully convince the unbelieving that there is one God, who has manifested Himself by Jesus Christ His Son, who is His eternal Word, not proceeding forth from silence, and who in all things pleased Him that sent Him.
Chapter 9. Let us live with Christ
If, therefore, those who were brought up in the ancient order of things 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 — whom some deny, by which mystery we have obtained faith, and therefore endure, that we may be found the disciples of Jesus Christ, our only Master — how shall we be able to live apart from Him, whose disciples the prophets themselves in the Spirit did wait for Him as their Teacher? And therefore He whom they rightly waited for, having come, raised them from the dead. Matthew 27:52 (Epistle to the Magnesians [A.D. 110])
Justin Martyr
Chapter 67. Weekly worship of the Christians
And we afterwards continually remind each other of these things. And the wealthy among us help the needy; and we always keep together; and for all things wherewith we are supplied, we bless the Maker of all through His Son Jesus Christ, and through the Holy Ghost. And on the day called Sunday, all who live in cities or in the country gather together to one place, and the memoirs of the apostles or the writings of the prophets are read, as long as time permits; then, when the reader has ceased, the president verbally instructs, and exhorts to the imitation of these good things. Then we all rise together and pray, and, as we before said, when our prayer is ended, bread and wine and water are brought, and the president in like manner offers prayers and thanksgivings, according to his ability, and the people assent, saying Amen; and there is a distribution to each, and a participation of that over which thanks have been given, and to those who are absent a portion is sent by the deacons. And they who are well to do, and willing, give what each thinks fit; and what is collected is deposited with the president, who succours the orphans and widows and those who, through sickness or any other cause, are in want, and those who are in bonds and the strangers sojourning among us, and in a word takes care of all who are in need. 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 Saviour on the same day rose from the dead. For He was crucified on the day before that of Saturn (Saturday); and on the day after that of Saturn, which is the day of the Sun, having appeared to His apostles and disciples, He taught them these things, which we have submitted to you also for your consideration. (First Apology [A.D. 155])

Some religious organizations claim the Church "changed" the day of worship from Saturday to Sunday, but Scripture and Tradition reveal something else.
