“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.
