As we have uncovered in many other studies, no where in the Bible is Sunday mentioned as a day of worship. Click here to read all instances where the “First Day” of the week is mentioned.
Actually, only ONE verse does indicate the apostles meeting on Sunday. In this meeting, Paul was preparing to leave the following day and so they spent the day listening to the teachings of Paul until midnight.
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
This meeting did not indicate a weekly worship on Sunday. Obviously Paul had been ministering to them on the Sabbath and the meeting was an extension of the teachings.
What about Sabbath? We know the Sabbath is actually the Lord’s day. Why?
For the Son of man is Lord even of the sabbath day. Matthew 12:8
So if Christ is the Lord of the Sabbath, why is Sunday called the Lord’s day?
Pope Sylvester, by his apostolical authority, changed the name of the day, giving it the imposing title of “Lord’s Day.” (SeeEcclesiastical History of Lucius, cent. 4, cap. 10, Pages 739, 740.) It had been called by that title by a few writers before; but Sylvester, as head of the church, now officially decided that its title should be “Lord’s Day.” Thus Constantine elevated the Sunday as a heathen festival to be observed throughout the empire, while Sylvester changed it into a Christian institution, dignifying it by the title of “Lord’s Day.”
Concerning the grounds upon which Sunday stands, we will here give a quotation from Dr. Heylyn:
“Thus do we see upon what grounds the Lord’s day stands: on custom first and voluntary consecration of it to religious meetings; that custom countenanced by the authority of the church of God, which tacitly approved the same; and finally confirmed and ratified by the Christian princes throughout their empires. And as the day for rest from labors and restraint from business upon that day, [it] received its greatest strength from the supreme magistrate”
Even the Baptists agree
Baptist: “There was and is a commandment to keep holy the Sabbath day, but that Sabbath day was not Sunday.. It will be said, however, and with some show of triumph, that the Sabbath was transferred from the seventh to the first day of the week … Where can the record of such a transfer be found? Not in the New Testament ? absolutely not. Of course, I quite well know that Sunday did come into use in early Christian history.. But what a pity that it comes branded with the mark of paganism, and christened with the name of the sun god, when adopted and sanctioned by the Papal apostasy, and bequeathed as a sacred legacy to Protestantism!” ? Dr E.T.Hiscox, author of “The Baptist Manual. “
What difference does it make which day I keep? A day is a day, isn’t it?
“Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?” Romans 6:16.
Then what shall I do, obey the Sabbath of God’s commandment or keep the Sunday of man?
“We ought to obey God rather than men.” Acts 5:29.
