But this did not produce any material change, for Socrates, a writer of the fifth century, who resided at Constantinople, makes the following remarks upon the celebration of the Sabbath at the time he wrote, A. D. 440. He says, "There are various customs concerning assembling; for though all the churches throughout the whole world celebrate the sacred mysteries on the Sabbath day, yet the Alexandrians and the Romans, from an ancient tradition, refuse to do this; but the Egyptians who are in the neighborhood of Alexandria, and those inhabiting Thebais, indeed have assemblies on the Sabbath, but do not participate in the mysteries, as is the custom of the Christians. At Cæsarea, Cappadocia, and in Cyprus, on the Sabbath and Dominical day, at twilight, with lighted lamps, the presbyters and bishops interpret the Scriptures. At Rome they fast every Sabbath."

This account of the manner of celebrating the Sabbath in the fifth century, is corroborated by Sozomen, in his Ecclesiastical History, b. 7, c. 9. He says, "At Constantinople, and almost among all, the Christians assembled upon the Sabbath, and also upon the first day of the week, excepting at Rome and Alexandria; the ecclesiastical assemblies at Rome were not upon the Sabbath, as in almost all other churches of the rest of the world; and in many cities and villages in Egypt, they used to commune in the evening of the Sabbath, on which day there were public assemblies."

In regard to fasting on the Sabbath at Rome, referred to by Socrates, it ought to be said, that from the earliest times to the fourth century, the practice had been to observe the Sabbath as a holiday. But the Church of Rome, in its opposition to the Jews, made it a fast day, that the separation might be marked and strong. In the eastern churches they never fasted upon the Sabbath, excepting one Sabbath in the year, which was the day before the Passover. But in the western churches they celebrated a fast every week. It was in reference to this that Ambrose said, "When I come to Rome, I fast upon the Sabbath; when I am here, I do not fast." Augustine also said concerning this, "If they say it is sinful to fast on the Sabbath, then they would condemn the Roman Church, and many places near to and far from it. And if they should think it a sin not to fast on the Sabbath, then they would blame many eastern churches, and the far greater part of the world." This Sabbath fasting was opposed by the eastern church; and in the sixth general council, held at Constantinople, it was commanded that the Sabbath and Dominical days be kept as festivals, and that no one fast or mourn upon them. The practice of fasting, therefore, was chiefly in the western churches, about Rome.

It is perhaps difficult to determine exactly the relative importance attached to the seventh and first days of the week at this time. Sufficient may be found, however, to assure us, that the Sabbath was observed, and that no one regarded Sunday as having taken its place. This is shown by the provision of the Council of Laodicea, A. D. 365, that the Gospels should be read on that day. It is shown by the action of a Council in 517, (mentioned in Robinson's History of Baptism,) which regulated and enforced the observance of the Sabbath. It is shown by the expostulation of Gregory of Nyssa, "How can you look upon the Lord's day, if you neglect the Sabbath? Do you not know that they are sisters, and that in despising the one you affront the other?" And as sisters we find them hand in hand in the ecclesiastical canons. Penalties were inflicted by the council; both of Laodicea and Trullo, on clergymen who did not observe both days as festivals.

How the first day of the week, or Lord's day, was observed in the early part of the fifth century, we may learn from the words of St. Jerome. In a funeral oration for the Lady Paula, he says: "She, with all her virgins and widows who lived at Bethlehem in a cloister with her, upon the Lord's day, repaired duly to the church, or house of God, which was nigh to her cell; and after her return from thence to her own lodgings, she herself and all her company fell to work, and they all performed their task, which was the making of clothes and garments for themselves and for others, as they were appointed."

St. Chrysostom, patriarch of Constantinople, "recommended to his audience, after impressing upon themselves and their families what they had heard on the Lord's day, to return to their daily employments and trades."

Dr. Francis White, Lord Bishop of Ely, speaking of this matter, says, "The Catholic Church, for more than six hundred years after Christ, permitted labor, and gave license to many Christian people to work upon the Lord's day, at such hours as they were not commanded to be present at the public service by the precepts of the church."

In the sixth century efforts were made to prevent this labor. The following promulgation of a synod held by command of King Junthran, of Burgundy, will show the condition of things, and the means used to improve it; "We see the Christian people, in an unadvised manner, deliver to contempt the Dominical day, and, as in other days, indulge on continual labor." Therefore they determined to teach the people subject to them to keep the Dominical day, which, if not observed by the lawyer, he should irreparably lose his cause, and if a countryman or servant did not keep it, he should be beaten with heavier blows of cudgels. The council of Orleans, held 538, prohibited the country labor on Sunday which Constantine by his laws permitted. According to Chambers, this council also declared, "that to hold it unlawful to travel with horses, cattle, and carriages, to prepare food, or to do any thing necessary to the cleanliness and decency of houses or persons, savors more of Judaism than Christianity." According to Lucius, in another council held in Narbonne, in France, in the seventh century, they also forbid this country work.

Early in the seventh century, in the time of Pope Gregory I., the subject of the Sabbath attracted considerable attention. There was one class of persons who declared, "that it was not lawful to do any manner of work upon the Saturday, or the old Sabbath; another, that no man ought to bathe himself on the Lord's day, or their new Sabbath." Against both of these doctrines Pope Gregory wrote a letter to the Roman citizens. Baronius, in his Councils, says, "This year (603) at Rome, St. Gregory, the Pope, corrected that error which some preached, by Jewish superstition, or the Grecian custom, that it was a duty to worship on the Sabbath, as likewise upon the Dominical day;" and he calls such preachers the preachers of Antichrist.

Nearly the same doctrine was preached again in the time of Gregory VII., A. D. 1074, about five hundred years after what we are now speaking of. This is sufficient to show that the Sabbath was kept until those times of decline which introduced so many errors in faith and practice. Indeed, it is sufficient to show, that wherever the subject has been under discussion, the Sabbath has found its advocates, both in theory and in practice.
