And upon the "first day" of the week - Let's have church!

In the Bible, what took place on the “first day” of the week?

The first mention of the “first day” is when God commanded the light to shine out of darkness. (2Corinthians 4:6). This was on the “first day” of the very first week.

"And God said, Let there be light: and there was light... And the evening and the morning were the first day." - Genesis 1:3, 5 KJV

In the New Testament, the first mention of the “first day” of the week is the day of Jesus’ resurrection.

"In the end of the sabbath, as it began to dawn toward the first day of the week, came Mary Magdalene and the other Mary to see the sepulchre." - Matthew 28:1 KJV

"Now when Jesus was risen early the first day of the week, he appeared first to Mary Magdalene, out of whom he had cast seven devils." - Mark 16:9 KJV

Next, the “first day” of the week is mentioned after Jesus’ resurrection when the disciples were assembled and Jesus appeared to them.

"Then the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled for fear of the Jews, came Jesus and stood in the midst, and saith unto them, Peace be unto you." - John 20:19 KJV

It was on this day, the “first day” of the week, that Jesus gave His disciples the ‘Great Commission,’ as recorded by John. (John 20:21-23).

Next, is when the believers were gathered together and Paul preached to them.

"And upon the first day of the week, when the disciples came together to break bread, Paul preached unto them, ready to depart on the morrow; and continued his speech until midnight." - Acts 20:7 KJV

Next, it was on the “first day” of the week that the church in Corinth was to bring an offering for the saints in Jerusalem (NLT), according to Paul’s instruction.

"Now concerning the collection for the saints, as I have given order to the churches of Galatia, even so do ye. 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." - 1 Corinthians 16:1-2 KJV (Another translation: “On the first day of each week, you should each put aside a portion of the money you have earned. Don’t wait until I get there and then try to collect it all at once.”).

In Revelation, John spoke of being in the Spirit on “the Lord’s day.” The Lord’s day sounds to be the “first day” of the week, the way Thayer’s Greek Lexicon describes it. (As Christ’s resurrection was on the “first day” of the week.)

"I was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet," - Revelation 1:10 KJV [“the day devoted to the Lord, sacred to the memory of Christ's resurrection, Revelation 1:10” - Thayer’s Greek Lexicon.] Another translation: “It was the Lord’s Day, and I was worshiping in the Spirit...”

The Jews know the “first day” of the week as, “Yom Rishon.” We know the “first day” of the week as Sunday.
