As no writer before Eusebius had ever hinted at the doctrine of the change of the Sabbath, and as there is the most convincing proof, as we have shown, that before his time Sunday possessed no Sabbatic character, and as Eusebius does not claim that this doctrine is asserted in the Scriptures, nor in any preceding ecclesiastical writer, it is certain that he was the father of the doctrine. This new doctrine was not put forth without some motive. That motive could not have been to bring forward some neglected passages of the Scriptures; for he does not quote a single text in its support. But the circumstances of the case plainly reveal the motive. The new doctrine was exactly adapted to the new order of things introduced by Constantine. It was, moreover, peculiarly suited to flatter that emperor’s pride, the very thing which Eusebius was under the strongest temptation to do. It is remarkable, however, that Eusebius, in the very connection in which he announces this new doctrine, unwittingly exposes its falsity. He first asserts that Christ changed the Sabbath, and then virtually contradicts it by indicating the real authors of the change. Thus he says:— “All things whatsoever that it was duty to do on the Sabbath, these WE have transferred to the Lord’s day.”[762] The persons here referred to as the authors of this work are the Emperor Constantine, and such bishops as Eusebius, who loved the favor of princes, and Sylvester, the pretended successor of Saint Peter. Two facts refute the assertion of Eusebius that Christ changed the Sabbath: 1. That Eusebius, who lived three hundred years after the alleged change, is the first man who mentions such change; 2. That Eusebius testifies that himself and others made this change, which they could not have done had Christ made it at the beginning. But though the doctrine of the change of the Sabbath was thus announced by Eusebius, it was not seconded by any writer of that age. The doctrine had never been heard of before, and Eusebius had simply his own assertion, but no passage of the Holy Scriptures to offer in its support. But after Constantine, the Sabbath began to recover strength, at least in the eastern churches. Prof. Stuart, in speaking of the period from Constantine to the council of Laodicea, A. D. 364, says:— “The practice of it [the keeping of the Sabbath] was continued by Christians who were jealous for the honor of the Mosaic law, and finally became, as we have seen, predominant throughout Christendom. It was supposed at length that the fourth commandment did require the observance of the seventh-day Sabbath (not merely a seventh part of time), and reasoning as Christians of the present day are wont to do, viz., that _all_ which belonged to the ten commandments was immutable and perpetual, the churches in general came gradually to regard the seventh-day Sabbath as altogether sacred.”[763]
