The following statements confirm the change and the Sabbath is still Gods’ Holy Day.
The First Sunday Law
“On the Venerable Day of the Sun [“venerabili die Solis”–the sacred day of the Sun] let the magistrates and people residing in cities rest, and let all workshops be closed. In the country, however, persons engaged in agriculture may freely and lawfully continue their pursuits; because it often happens that another day is not so suitable for grain-sowing or for vine-planting; lest by neglecting the proper moment for such operations the bounty of heaven should be lost–Given the 7th day of March, [A.D. 321], Crispus and Constantine being consuls each of them for the second time.” The First Sunday Law of Constantine 1, in “Codex Justinianus,” lib. 3, tit. 12, 3; trans. in Phillip Schaff “History of the Christian Church,” Vol. 3, p. 380.
“Christians shall not Judaize and be idle on Saturday [in the original: “sabbato” shall not be idle on the Sabbath], but shall work on that day; but the Lord’s day they shall especially honour, and as being Christians, shall, if possible, do no work on that day. If, however, they are found Judaizing, they shall be shut out [“anathema,”–excommunicated] from Christ.” Council of Laodicea, c. A.D. 337, Canon 29, quoted in C.J. Hefele, “A History of the Councils of the Church,” Vol. 2, p. 316.
It was the Roman Catholic Church(the Pope) that placed Sunday law as Cannon Law XXIX(which cannot be disputed) in 364 A.D. at the Council of Laodicea. Canon Law XXIX states: “Christians must not judaize by resting on the Sabbath, but must work on that day, rather honouring the Lord’s Day; and, if they can, resting then as Christians. But if any shall be found to be judaizers, let them be anathema from Christ.”
The continuing of Sabbath observance under great pressure .
“The inquisitors…(declare) that the sign of a Vaudois (Waldeneses of France, Sabbathkeepers) deemed worthy of death, was that he followed Christ and sought to obey the commandments of God” – History of the Inquisition of the Middle Ages, H.C. Lea, Vol 1.
Catholic Church declares they changed the Day.
“The Bible says, Remember that thou keep holy the Sabbath day. The Catholic church says, No! By my divine power I abolish the Sabbath day, and command you to keep the first day of the week. And lo, the entire civilized world bows down in reverent obedience to the command of the holy Catholic church!” Father Enright, C.S.S.R. of the Redemptoral College, Kansas City, History of the Sabbath, p. 802
“Perhaps the boldest thing, the most revolutionary change the Church ever did, happened in the first century. The holy day, the Sabbath, was changed from Saturday to Sunday. ‘The day of the Lord’ was chosen, not from any direction noted in the Scriptures, but from the Church’s sense of its own power….People who think that the Scriptures should be the sole authority, should logically…keep Saturday holy.” St. Catherine Church Sentinel, Algonac, Michigan, May 21, 1995.
D. L. Moody declared the Sabbath Still binding.
The Sabbath was binding in Eden, and it has been in force ever since. This fourth commandment begins with the word ‘remember,’ showing that the Sabbath already existed when God Wrote the law on the tables of stone at Sinai. How can men claim that this one commandment has been done away with when they will admit that the other nine are still binding?”
D. L. Moody, Weighed and Wanting (Fleming H. Revell Co.: New York), pp. 47, 48.
Paul made this statement which miss use, in his time a day started at sunset until sunset. This means sunset Saturday was the start of the first day (Sunday).
7 On the first day of the week we came together to break bread. Paul spoke to the people and, because he intended to leave the next day, kept on talking until midnight.
8 There were many lamps in the upstairs room where we were meeting.
9 Seated in a window was a young man named Eutychus, who was sinking into a deep sleep as Paul talked on and on. When he was sound asleep, he fell to the ground from the third story and was picked up dead.
10 Paul went down, threw himself on the young man and put his arms around him. “Don’t be alarmed,” he said. “He’s alive!”
11 Then he went upstairs again and broke bread and ate. After talking until daylight, he left.
12 The people took the young man home alive and were greatly comforted. Act 20:7-12 niv
While most Christians observe Sunday as their day of worship, many still worship on the Sabbath.
