"The primitive Christians did keep the Sabbath of the Jews;.therefore the Christians for a long time together, did keep their conventions on the Sabbath, in which some portion of the Law were read: and this continued till the time of the Laodicean council." The Whole Works of Jeremey Taylor, Vol. IX, p416 (R. Heber's Edition, Vol.XII, p.416)
"The ancient Christians were very careful in the observation of Saturday, or the seventh day..It is plain that all the Oriental churches, and the greatest part of the world, observed the Sabbath as a festival...Athanasius likewise tells us that they held religious assemblies on the Sabbath, not because they were infected with Judaism, but to worship [Yahushua], the [Master] of the Sabbath, Epiphanius says the same." Antiquities of the Christian Church, Vol. II, Book XX, chap. 3, Sec. 1, 66.1137, 1138
"Ambrose, the celebrated bishop of Milan, said that when he was in Milan he observed Saturday, but when in Rome observed Sunday. This gave rise to the proverb 'When you are in Rome, do as Rome does,' " Heylyn, The History of the Sabbath, 1613
Constantine later enforced keeping a Sabbath on the first day of the week, which he calls "the venerable day of the sun." Venerable means 'commanding respect'.
The text of Constantine's Sunday Law of 321 A.D. is:
"One the venerable 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 suitable for gain-sowing or vine planting; lest by neglecting the proper moment for such operations the bounty of heaven should be lost."
This doesn't even really sound like Yahweh's Sabbath which forbids any kind of work at all on His day!
Later, those who observed the Sabbath were persecuted and killed by the Catholic church. When the Jesuit St. Francis Xavier arrived in India he immediately requested to the pope to set up the Inquisition there.
"The Jewish wickedness" of which Xavier complained was evidently the Sabbath-keeping among those native Christians as we shall see in our next quotation. When one of these Sabbath-keeping Christians was taken by the Inquisition he was accused of having *Judaized*; which means having conformed to the ceremonies of the Mosaic Law; such as not eating pork, hare, fish without scales, of having attended the solemnization of the Sabbath." Account of the Inquisition at Goa, Dellon, p.56. London, 1815
"Of an hundred persons condemned to be burnt as Jews, there are scarcely four who profess that faith at their death; the rest exclaiming and protesting to their last gasp that they are Christians, and have been so during their whole lives." Ibid p.64
Today, some of the leading Baptists even have admitted that the Sunday Sabbath isn't in the scriptures:
"There was and is a commandment to keep holy the Sabbath day, but that Sabbath day was not on 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 transaction be found? Not in the New Testament. Of course, I quite well know that Sunday did come into use in early Christian history as a religious day, as we learn from the Christian Fathers and other sources. But what a pity that it comes branded with the mark of paganism, and christened with the name of a sun god, when adopted and sanctioned by the papal apostasy, and bequeathed as a sacred legacy to Protestantism!" Dr. Edward Hiscox, author of The Baptist Manual
The Disciples Kept the Sabbath 85 Times in Acts
"The monks sent to England [in 596 A.D.] by Pope Gregory the Great soon came to see that the Celtic Church differed from theirs in many respects…Augustine himself [a Benedictine abbot]…held several conferences with the Christian Celts in order to accomplish the difficult task of their subjugation [submission] to Roman authority…The Celts permitted their priests to marry, the Romans forbade it. The Celts used a different mode of baptism [i.e., true baptism: immersion] from that of the Romans…The Celts held their own councils and enacted their own laws, independent of Rome. The Celts used a Latin Bible [i.e., the Itala] unlike the [Roman Catholic's Latin] Vulgate, and kept Saturday as a day of rest.” (A.C. Flick, The Rise of Medieval Church, p.236-327)
"It seems to have been customary in the Celtic churches of early times, in Ireland as well as Scotland, to keep Saturday, the Jewish Sabbath, as a day of rest from labor. They obeyed the fourth commandment literally upon the seventh day of the week." (James C. Moffatt, D. D.,The Church in Scotland, Philadelphia: 1882, p.140)
"In this latter instance they seemed to have followed a custom of which we find traces in the early monastic church of Ireland by which they held Saturday to be the Sabbath on which they rested from all their labours." (W.T. Skene, Adamnan Life of St. Columba, 1874, p.96)
"It is probable that the primitive Christians kept the Pasch on the 14th of Nisan as determined by the Jewish authorities, and regarded it as the anniversary of the crucifixion. ...The churches of the Roman province of Asia...followed the older custom, keeping the Pasch on the 14th of Nisan, whatever the day of the week." (James F. Kenney, The Sources for the Early History of Ireland, Vol.1, pp.211, 212; Columbia University Press, New York, 1929)
"...they ignorantly refuse to observe our Easter [Pascha] on which Christ was sacrificed, arguing that it should be observed with the Hebrew Passover on the fourteenth of the moon." (Bede, Historia Ecclesiastica, II, 19 wherein Bede quoted "Pope" John's words concerning the Celtic brethren)
