In 1 Corinthians 16 Paul wrote:
1 Corinthians 16:1-3 "1 Now concerning the collection for the saints, as I have given order to the churches of Galatia, even so do ye. 2 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. 3 And when I come, whomsoever ye shall approve by your letters, them will I send to bring your liberality unto Jerusalem."
Please carefully notice what the apostle said, and what he did not say. Many have assumed that a religious meeting was held and a collection plate passed around. This is not the case. Paul was writing special appeals to the churches in Asia Minor, because many of the Christians in Jerusalem were suffering greatly for lack of food and daily necessities. Paul asked the church at Corinth to gather food, clothing, etc., and store it up at home until he could send men to transport it to Jerusalem. The expression "lay by him in store" in the original Greek gives the clear connotation of putting aside at home. Even Sunday advocates agree to this.
There was no service held on the first day of the week. The gathering up and storing was to be done on that day. Why did Paul suggest that this work be done on Sunday, and what was involved in getting it done?
First, the letter would have been shared with the church on the Sabbath when they were all gathered for worship. The first opportunity to do the work would be the next day—the first day of the week. Keep in mind that there was an apparent food shortage in Jerusalem, and the need was not primarily for money. Such famine conditions were not unusual in areas of the Middle East, as Luke reminds us in Acts.
Acts 11:28–30 "28 And there stood up one of them named Agabus, and signified by the Spirit that there should be great dearth throughout all the world: which came to pass in the days of Claudius Caesar. 29 Then the disciples, every man according to his ability, determined to send relief unto the brethren which dwelt in Judaea: 30 Which also they did, and sent it to the elders by the hands of Barnabas and Saul."
The church in Rome gives a clue as to the special needs of those suffering Christians.
Romans 15:25–28 "25 But now I go unto Jerusalem to minister unto the saints. 26 For it hath pleased them of Macedonia and Achaia to make a certain contribution for the poor saints which are at Jerusalem. 27 It hath pleased them verily; and their debtors they are. For if the Gentiles have been made partakers of their spiritual things, their duty is also to minister unto them in carnal things. 28 When therefore I have performed this, and have sealed to them this fruit, I will come by you into Spain."
Here the apostle touches a tender spot in his eloquent appeal. The Roman Christians owed a great debt of gratitude to the mother church in Jerusalem that had sent teachers to evangelize them. Paul urges them to return carnal, or material, gifts in appreciation of the spiritual truths received from them. What kind of gifts did Paul have in mind? It is very interesting that he describes it as sealing to them "this fruit". The Greek word used here is "karpos," which is the universal term used for literal fruit. It can also have the connotation of "fruits of one's labor."
This throws light on Paul's counsel to the Corinthian Christians to do their work on the first day of the week, "so that there be no gatherings when I come". Such work as gathering and storing up produce from garden and field would certainly not be appropriate on Sabbath. In these verses, Sunday is identified once again as a day for secular activities and gives no indication of religious observance.
