That the observance of the Sabbath was not confined to Jewish converts, the learned Giesler explicitly testifies:—
“While the Jewish Christians of Palestine retained the entire Mosaic law, and consequently the Jewish festivals, the Gentile Christians observed also the Sabbath and the passover,[708] with reference to the last scenes of Jesus’ life, but without Jewish superstition. In addition to these, Sunday, as the day of Christ’s resurrection, was devoted to religious services.”[709]
The statement of Mosheim may be thought to contradict that of Giesler. Thus he says:—
“The seventh day of the week was also observed as a festival, not by the Christians in general, but by such churches only as were principally composed of Jewish converts, nor did the other Christians censure this custom as criminal and unlawful.”[710]
It will be observed that Mosheim does not deny that the Jewish converts observed the Sabbath. He denies that this was done by the Gentile Christians. The proof on which he rests this denial is thus stated by him:—
“The churches of Bithynia, of which Pliny speaks, in his letter to Trajan, had only one stated day for the celebration of public worship; and that was undoubtedly the first day of the week, or what we call the Lord’s day.”[711]
The proposition to be proved is this: The Gentile Christians did not observe the Sabbath. The proof is found in the following fact: The churches of Bithynia assembled on a stated day for the celebration of divine worship. It is seen therefore that the conclusion is gratuitous, and wholly unauthorized by the testimony.[712] But this instance shows the dexterity of Mosheim in drawing inferences, and gives us some insight into the kind of evidence which supports some of these sweeping statements in behalf of Sunday. Who can say that this “stated day” was not the very day enjoined in the fourth commandment? Of the Sabbath and first day in the early ages of the church, Coleman speaks as follows:—
“The last day of the week was strictly kept in connection with that of the first day, for a long time after the overthrow of the temple and its worship. Down even to the fifth century the observance of the Jewish Sabbath was continued in the Christian church, but with a rigor and solemnity gradually diminishing until it was wholly discontinued.”[713]
This is a most explicit acknowledgment that the Bible Sabbath was long observed by the body of the Christian church. Coleman is a first-day writer, and therefore not likely to state the case too strongly in behalf of the seventh day. He is a modern writer, but we have already proved his statements true out of the ancients. It is true that Coleman speaks also of the first day of the week, yet his subsequent language shows that it was a long while before this became a sacred day. Thus he says:—
