Question: Why do churches gather on Sundays?
Acts 20:7 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.
There are only a few passages in the New Testament that tell what day of the week the early Christians gathered. The above passage clearly states that they met on the first day of the week to break bread, in other words, to eat the Lord’s supper.
The Sabbath, Saturday, is the seventh day of the week, so Sunday is the first day of the week. In the Genesis account, God created light on the first day, but then He rested on the seventh day.
A passage in Paul’s letter to the Corinthians also infers that the Christians were gathering on the first day of the week.
1 Corinthians 16:1 Now concerning the collection for the saints, as I have given orders to the churches of Galatia, so you must do also:
2 On the first day of the week let each one of you lay something aside, storing up as he may prosper, that there be no collections when I come.
In the above passage from 1 Corinthians, Paul told them to lay something aside for the collection of the saints on the first day of the week. Surely he says the first day of the week because they were already meeting together on this day.
Why did the church meet on Sunday?
The Bible doesn’t plainly say why they met on Sunday. However, I believe we can confidently infer that Christians met on the first day of the week because that was the day Jesus resurrected from the dead. See the passages below.
1 Now after the Sabbath, as the first day of the week began to dawn, Mary Magdalene and the other Mary came to see the tomb.
2 And behold, there was a great earthquake; for an angel of the Lord descended from heaven, and came and rolled back the stone from the door, and sat on it.
3 His countenance was like lightning, and his clothing as white as snow.
4 And the guards shook for fear of him, and became like dead men.
5 But the angel answered and said to the women, “Do not be afraid, for I know that you seek Jesus who was crucified.
6 “He is not here; for He is risen, as He said. Come, see the place where the Lord lay.
9 Now when He rose early on the first day of the week, He appeared first to Mary Magdalene, out of whom He had cast seven demons.
10 She went and told those who had been with Him, as they mourned and wept.
Is it a sin to gather together on another day other than Sunday?
I do not think it is a sin to gather on a different day other than Sunday. I know of some churches which offer a Saturday meeting. Many churches meet on Wednesdays in addition to their Sunday meeting. However, I prefer to meet with Christians that gather on Sunday. Sunday meetings appear to be the pattern established by the contemporaries of Jesus himself. And I believe the meetings were specifically on Sunday to reinforce the significance of Jesus’ resurrection from the dead on the first day of the week. Jesus instituted His supper on a Friday, Moses law required Jews to keep the Sabbath on Saturday, but the early Christians met on Sunday. The resurrection of Jesus is the most important event in redemptive history. Therefore, it is no surprise that they gathered together on the resurrection day – Sunday – The Lord’s Day.
Enjoy Your Sunday Meeting.
God bless. Bob
