“That very day was the Sunday of their heathen neighbors and respective countrymen; and patriotism gladly united with expediency in making it at once their Lord’s day and their Sabbath.... If the authority of the church is to be ignored altogether by Protestants, there is no matter; because opportunity and common expediency are surely argument enough for so ceremonial a change as the mere day of the week for the observance of the rest and holy convocation of the Jewish Sabbath. That primitive church, in fact, was shut up to the adoption of the Sunday, until it became established and supreme, when it was too late to make another alteration; and it was no irreverent nor undelightful thing to adopt it, inasmuch as the first day of the week was their own high day at any rate; so that their compliance and civility were rewarded by the redoubled sanctity of their quiet festival.”[539]

It would seem that something more potent than “patriotism” and “expediency” would be requisite to transform this heathen festival into the Christian Sabbath, or even to justify its introduction into the Christian church. A further statement of the reasons which prompted its introduction, and a brief notice of the earlier steps toward transforming it into a Christian institution, will occupy the remainder of this chapter. Chafie, a clergyman of the English Church, in 1652, published a work in vindication of first-day observance, entitled, “The Seventh-day Sabbath.” After showing the general observance of Sunday by the heathen world in the early ages of the church, Chafie thus states the reasons which forbid the Christians attempting to keep any other day:—

“1. Because of the contempt, scorn, and derision they thereby should be had in, among all the Gentiles with whom they lived.... How grievous would be their taunts and reproaches against the poor Christians living with them and under their power for their new set sacred day, had the Christians chosen any other than the Sunday.... 2. Most Christians then were either servants or of the poorer sort of people; and the Gentiles, most probably, would not give their servants liberty to cease from working on any other set day constantly, except on their Sunday.... 3. Because had they assayed such a change it would have been but labor in vain; ... they could never have brought it to pass.”[540]

Thus it is seen that at the time when the early church began to apostatize from God and to foster in its bosom human ordinances, the heathen world—as they had long done—very generally observed the first day of the week in honor of the sun. Many of the early fathers of the church had been heathen philosophers. Unfortunately they brought with them into the church many of their old notions and principles. Particularly did it occur to them that by uniting with the heathen in the day of weekly celebration they should greatly facilitate their conversion. The reasons which induced the church to adopt the ancient festival of the heathen as something made ready to hand, are thus stated by Morer:—

“It is not to be denied but we borrow the name of this day from the ancient Greeks and Romans, and we allow that the old Egyptians worshiped the sun, and as a standing memorial of their veneration, dedicated this day to him. And we find by the influence of their examples, other nations, and among them the Jews themselves, doing him homage;[541] yet these abuses did not hinder the fathers of the Christian church simply to repeal, or altogether lay by, the day or its name, but only to sanctify and improve both, as they did also the pagan temples polluted before with idolatrous services, and other instances wherein those good men were always tender to work any other change than what was evidently necessary, and in such things as were plainly inconsistent with the Christian religion; so that Sunday being the day on which the Gentiles solemnly adored that planet, and called it Sunday, partly from its influence on that day especially, and partly in respect to its divine body (as they conceived it), the Christians thought fit to keep the same day and the same name of it, that they might not appear causelessly peevish, and by that means hinder the conversion of the Gentiles, and bring a greater prejudice than might be otherwise taken against the gospel.”[542]

In the time of Justin Martyr, Sunday was a weekly festival, widely celebrated by the heathen in honor of their god, the sun. And so, in presenting to the heathen emperor of Rome an “Apology” for his brethren, Justin takes care to tell him thrice that the Christians held their assemblies on this day of general observance.[543] Sunday therefore makes its first appearance in the Christian church as an institution identical in time with the weekly festival of the heathen, and Justin, who first mentions this festival, had been a heathen philosopher. Sixty years later, Tertullian acknowledges that it was not without an appearance of truth that men declared the sun to be the god of the Christians. But he answered that though they worshiped toward the east like the heathen, and devoted Sunday to rejoicing, it was for a reason far different from sun-worship.[544] And on another occasion, in defending his brethren from the charge of sun-worship, he acknowledges that these acts, prayer toward the east, and making Sunday a day of festivity, did give men a chance to think the sun was the God of the Christians.[545] Tertullian is therefore a witness to the fact that Sunday was a heathen festival when it obtained a foothold in the Christian church, and that the Christians, in consequence of observing it, were taunted with being sun-worshipers. It is remarkable that in his replies he never claims for their observance any divine precept or apostolic example. His principal point was that they had as good a right to do it as the heathen had. One hundred and twenty one years after Tertullian, Constantine, while yet a heathen, put forth his famous edict in behalf of the heathen festival of the sun, which day he pronounced “venerable.” And this heathen law caused the day to be observed everywhere throughout the Roman Empire, and firmly established it both in Church and State. It is certain, therefore, that at the time of its entrance into the Christian church, Sunday was an ancient weekly festival of the heathen world.

That this heathen festival was upon the day of Christ’s resurrection doubtless powerfully contributed to aid “patriotism” and “expediency” in transforming it into the Lord’s day or Christian Sabbath. For, with pious motives, as we may reasonably conclude, the professed people of God early paid a voluntary regard to several days, memorable in the history of the Redeemer. Mosheim, whose testimony in behalf of Sunday has been presented already, uses the following language relative to the crucifixion day:—

“It is also probable that Friday, the day of Christ’s crucifixion, was early distinguished by particular honors from the other days of the week.”[546]

And of the second century, he says:—
