_The respect which the Gentiles had for the first day_, or Sunday, _while they were Pagans_, contributed much to render its introduction easy, and its weekly celebration popular, among such materials as composed the body of the church of Rome in the second, third, and fourth centuries. The observance of the first day of the week as a festival of the Sun, was very general in those nations from which the Gentile church received her converts. That an idolatrous worship was paid to the Sun and other heavenly bodies by the Gentiles, the Old Testament abundantly testifies; and this kind of adoration paid to the Sun in later times, is as plainly a matter of historical record. _Thomas Bampfield_, an English writer of the seventeenth century, quoting _Verstegan's_ Antiquities, p. 68, says: "Our ancestors in England, before the light of the Gospel came among them, went very far in this idolatry, and dedicated the first day of the week to the adoration of the idol of the Sun, and gave it the name of Sunday. This idol they placed in a temple, and there sacrificed to it." He further states, that from his historical reading, he finds that a great part of the world, and particularly those parts of it which have since embraced Christianity, did anciently adore the Sun upon Sunday. It is also stated by _Dr. Chambers_, in his Cyclopedia, that "Sunday was so called by our idolatrous ancestors, because set apart for the worship of the Sun." The Greeks and the Latins also gave the same name to the first day of the week. _Dr. Brownlee_, as quoted by _Kingsbury_, on the Sabbath, p. 223, also says, "When the descendants of Adam apostatized from the worship of the true God, they substituted in his place the Sun, that luminary which, more than all others, strikes the minds of savage people with religious awe; and which, therefore, all heathens worship." Attachment to particular days of religious celebration, from habit merely, is well known, even in our own day, to be very strong, and powerful convictions of duty are often required to produce a change. This was no doubt well understood by the teachers of Christianity in those times. _Dr. Mosheim_, when treating on that age, says, "that the leaders imagined that the nations would the more readily receive Christianity when they saw the rites and ceremonies to which they had been accustomed established in the churches, and the same worship paid to Jesus Christ and his martyrs which they had formerly offered to their idol deities. Hence it happened, that in those times, the religion of the Greeks and Romans differed but little in its external appearance from that of Christians."
