Thus far we have been guided by the inspired Scriptures, and we think they prove beyond dispute, that the Christians of the apostolic age had received no new doctrine concerning the Sabbath, but continued without any change to devote the seventh day of the week to the duties of religion. But we now enter a period in which the history of the Sabbath must be derived from other sources. It may be difficult to trace exactly every step which has been taken, as the histories of the early ages are very defective on many subjects. They have come to us, to a considerable extent, through the church of Rome; and since she claims to have changed the day of the Sabbath, it is not to be expected that testimony against herself would be very faithfully preserved. In pursuing our sketch, we shall follow the best lights we have to guide us. After the period described in the Acts of the Apostles, Christianity soon became widely spread in the Roman empire, which, at that time, extended over most of the civilized world. But as it receded from the time of the Apostles, and the number of its professors increased, the church became gradually less spiritual, and more disposed to deck the simple religion of Jesus with mysteries and superstitious formalities; and the bishops or pastors became ambitious of their authority over the churches. Those churches, even in Gentile cities, appear to have been composed, at first, principally of converted Jews, who not only observed the weekly Sabbath, but also the feast of the Passover, adapted particularly to Christian worship; respecting which, there was much contention. In the mean time, converts were greatly multiplied from among the Gentiles and were united with those from the Jews, who, not without reason, considered themselves entitled to some distinction as the original founders of the gospel church, and as being better informed in the writings of Moses and the prophets, having been in the habit of reading them every Sabbath in the synagogues.
