Upon the first day of the week let every one of you lay by him in store, as God hath prospered him, that there be no gatherings when I come. And when I come, whomsoever ye shall approve by your letters, them will I send to bring your liberality unto Jerusalem. And if it be meet that I go also, they shall go with me. Now I will come unto you, when I shall pass through Macedonia: for I do pass through Macedonia. And it may be that I will abide, yea, and winter with you, that ye may bring me on my journey whithersoever I go. For I will not see you now by the way; but I trust to tarry a while with you, if the Lord permit. But I will tarry at Ephesus until Pentecost. For a great door and effectual is opened unto me, and there are many adversaries. Now if Timotheus come, see that he may be with you without fear: for he worketh the work of the Lord, as I also do. Let no man therefore despise him: but conduct him forth in peace, that he may come unto me: for I look for him with the brethren. As touching our brother Apollos, I greatly desired him to come unto you with the brethren: but his will was not at all to come at this time; but he will come when he shall have convenient time. 1 Corinthians 16:2-12
I can’t tell you how many people reach out to me to argue over Sunday worship, The Lord’s Day. The argument is always “Constantine created Sunday worship from paganism”
When somebody makes a statement like that to me, it’s clear to me this person has very limited knowledge of Church history and the Bible. Many people see these statements online and just parroting them, without actually doing any research or study for themselves.
The recorded words of the Apostle Paul are very significant here for Church history and practical application for the Church today. Paul says “Upon the First Day of the week” Paul gives significance to the gathering of Christians on The Lord’s Day (Revelation 1:10) which is Sunday. The term “Lord’s Day” was used by the Apostle John in Revelation, it’s apparent this was already established as a term for Sunday, when Christ rose from the dead.
Now if you go back one verse Paul mentions the “Churches of Galatia” also. This was not just a commandment for the Church of Corinth, this appears to be a standard practice for the early Church to gather on Sunday morning for worship.
In the book of Acts it mentions meeting on Sunday multiple times,” Now on the first day of the week, when the disciples came together to break bread, Paul, ready to depart the next day, spoke to them and continued his message until midnight. “ (Acts 20:7)
So why did the early Christians worship on Sunday? Well what happened on Sunday morning? Yes Jesus Christ rose from the dead, all 4 gospels tell us it happened on “The First Day of the Week (Sunday) in the morning (Mark 16:9, John 20:1-2, Matthew 28:1, Luke 24:1) There is no paganism or mystery about gathering on Sunday morning if you read your Bible, the resurrection of Christ changed everything.
So what happened at the council of Nicaea? Constantine just established what the Christians were doing since the first century, The Church always revered Sunday as The Lord’s Day, and gathered and worshiped, because Jesus Christ is our Lord and rose from the dead! Amen!
