WRONG!
Passages of Scripture such as Acts 20:7, 1 Corinthians 16:2, Colossians 2:16-17, and Revelation 1:10 indicate that, even during New Testament times, the Sabbath is no longer binding and that Christians are to worship on the Lord’s day, Sunday, instead.
Let's start with the easy one...
Rev 1:10 I was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet,
What day in scripture is singled out as the Lord's Day? There are only three places a day is single out in the New Testament as being the day Christ is Lord of...
Mat 12:8 For the Son of man is Lord even of the sabbath day.
Mar 2:28 Therefore the Son of man is Lord also of the sabbath.
Luk 6:5 And he said unto them, That the Son of man is Lord also of the sabbath.
And that day ain't Sunday.
In fact, the passage in Rev 1:10 is not speaking to ANY particular day but rather a time in the future known as the Day of the Lord. The one year period following the Tribulation when God Almighty intervenes dramatically and culminates with the inception of His Kingdom on earth.
If you disagree, please show me where Rev 1:10 refers to ANY particular day of the week.
Now for Acts 20:7
Act 20:7 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.
First of all, when did the days begin? At sunset. Paul was preaching on Saturday night and continued to Midnight. After the miracle concerning Eutychus, notice that he continues to preach until morning. Now what morning is this? Sunday morning and what does Paul do on Sunday morning? He begins a 19 mile trek across the peninsula to meet with those who had sailed around previously...
Act 20:13 And we went before to ship, and sailed unto Assos, there intending to take in Paul: for so had he appointed, minding himself to go afoot.
Act 20:14 And when he met with us at Assos, we took him in, and came to Mitylene.
So, Paul kept this Sunday by walking 19 miles across the peninsula to Assos. Strange way to keep a Sunday mornin' go to meeting, isn't it?
Now for the passage in I Corinthians...
1Co 16:2 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.
First let's read the entire passage...
1Co 16:1 Now concerning the collection for the saints, as I have given order to the churches of Galatia, even so do ye.
1Co 16:2 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.
1Co 16:3 And when I come, whomsoever ye shall approve by your letters, them will I send to bring your liberality unto Jerusalem.
1Co 16:4 And if it be meet that I go also, they shall go with me.
1Co 16:5 Now I will come unto you, when I shall pass through Macedonia: for I do pass through Macedonia.
1Co 16:6 And it may be that I will abide, yea, and winter with you, that ye may bring me on my journey whithersoever I go.
Verse 1 raises a question, what collections?
Act 11:27 And in these days came prophets from Jerusalem unto Antioch.
Act 11:28 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.
Act 11:29 Then the disciples, every man according to his ability, determined to send relief unto the brethren which dwelt in Judaea:
Now let's read I Cor 16:2
1Co 16:2 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.
Please notice here it says NOTHING about tossing money in the collection plate, it says for each to lay in store so that the gathering is ready when Paul comes to them. So if this is about passing the plate, then each should TAKE from the plate, take it to his home and store it up until Paul arrives.
1Co 16:3 And when I come, whomsoever ye shall approve by your letters, them will I send to bring your liberality unto Jerusalem.
Notice where they are taking these stores of dried foods and fruits? To Jerusalem. Why? We read that previously...
Act 11:28 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.
Act 11:29 Then the disciples, every man according to his ability,
determined to send relief unto the brethren which dwelt in Judaea:
To send relief to the starving saints in the region of Judea. and who was going to do this?
1Co 16:3 And when
I come,
whomsoever ye shall approve by your letters, them will I send to bring your liberality unto Jerusalem.
And whom did they approve of?
Act 11:30 Which also they did, and sent it to the elders by the hands of
Barnabas and Saul.
In Paul's second letter to the Corinthians, he makes these remarks concerning this collection for the starving saints...
2Co 9:1 For as touching the ministering to the saints, it is superfluous for me to write to you:
2Co 9:2 For I know the forwardness of your mind, for which I boast of you to them of Macedonia, that Achaia was ready a year ago; and your zeal hath provoked very many.
2Co 9:3 Yet have I sent the brethren, lest our boasting of you should be in vain in this behalf; that, as I said, ye may be ready:
2Co 9:4 Lest haply if they of Macedonia come with me, and find you unprepared, we (that we say not, ye) should be ashamed in this same confident boasting.
2Co 9:5 Therefore I thought it necessary to exhort the brethren, that they would go before unto you, and make up beforehand your bounty, whereof ye had notice before, that the same might be ready, as a matter of bounty, and not as of covetousness.
Notice verse 4? Paul again admonishes them to lay up in store, to be prepared for when he comes so that the foodstuffs can be taken to Judea.
There is nothing in the three passages you mentioned that refers to Sunday go to meetin' at all. These are the three famous passages that every young trainee learns to justify Sunday keeping and each falls apart with the slightest of scrutiny.
