The gathering of the Apostles on the first day of the week was clearly recorded in scripture. There was no conflict for the Apostles between observing the Sabbath, and observing the Lord’s Day on the first day of the week.
What is clearly recorded in scripture is the gathering of the apostles on the first day of the week “for fear of the Jews” (John 20:19) – not to celebrate the resurrection. And how could they have gathered to celebrate the resurrection when at the time they did not believe that Jesus was resurrected (Mark 16:14; Luke 24:37, 39, 41)?
The next and LAST recorded gathering of the apostles on the first day of the week (Acts 20:7) happened on the day we now call Saturday night, not Sunday which is the Catholic Lord’s Day. At the very hour when the clock struck midnight to begin the day we call Sunday, Paul’s meeting ended. Then Paul, at break of day Sunday morning, engaged in the labor of walking some 20 miles to Assos, while his companions labored in rowing a boat some 60 long miles to rendezvous with the apostle – indeed a sacrilegious act had Sunday already been made the Christian holy day of worship.
No, the apostles NEVER observed the first day of the week as some special day, much less attempt to replace the Sabbath with it. Paul himself declared he kept the Law saying “so worship I the God of my fathers,
believing all things which are written in the law and the prophets” (Acts 24:14).
If Paul had been observing both the first day of the week AND the seventh, why did he not tell the Gentile converts in Antioch, after preaching to them on the Sabbath, that they can meet the very next day, Sunday? The Gentile converts had “besought that these words might be preached to them the next Sabbath” (Acts 13:42)? It would have been Paul’s best opportunity to straighten them out as to the new Lord’s Day for Christians. But, no, Paul waited the next Sabbath to preach to the Gentiles again, for we read: “And the next Sabbath day came almost all the city together to hear the word of God” (v. 46). Paul waited a whole week, passing up on Sunday, in order to preach to the Gentiles on the correct God-given day of Christian worship – the day God calls the “Sabbath of the Lord” – the seventh day of the week.
But it should come as no surprise to us that Paul kept only the seventh day Sabbath. It was his MANNER, his CUSTOM to keep the Sabbath holy and preach on that day. Paul, we read in Acts 17:2, “as his manner was, went in unto them, and three Sabbath days reasoned with them out of the scriptures.”
Now, here [again] is the frank admission by an authority of your church on the unscriptural observance of Sunday and the clear command in the Bible to instead observe the Sabbath:
“Is not the observance of this law among the most prominent of our sacred duties? But you may read the Bible from Genesis to Revelation, and
you will not find a single line authorizing the sanctification of Sunday. The Scriptures enforce the religious observance of Saturday, a day which we never sanctify” (Cardinal Gibbons,
The Faith of Our Fathers, p. 89).
And Cardinal Gibbons is not the only Catholic authority to admit that the Bible nowhere shows Sunday should be observed by Christians. Notice this from
A Course in Religion for Catholic High Schools and Academies, 1936 ed., vol. 1, by John Laux: “If we consulted the Bible only, we should still have to keep holy the Sabbath Day, that is, Saturday” (p. 51).
And here’s another from
The Catholic Mirror on its Sept. 23, 1893 publication: “God’s written word enjoins His worship to be observed on Saturday, absolutely, repeatedly, and most emphatically, with a most positive threat of death to him who disobeys.”
These Catholic authorities did not see even a hint in the entire scriptures to suggest that Sunday was observed by the apostles. They all agree God’s Sabbath is clearly established in His Word. Only those desperate for scriptural support to justify their Sunday worship can “see” something that is clearly not there.
