The Seventh Day Adventists say that the Apostles had no right nor power to change the Sabbath into the Sunday. Christ, they say, came to fulfill the Law of God, and not one iota has been broken. They maintain that the resurrection of Christ on a Sunday, and the descent of the Holy Ghost on a Sunday are no reason to change the Law. - PROVIDENCE, R. I.
The Apostles did not change the Sabbath into the Sunday; they remain distinct days of the week. But what the Apostles and their successors did was to
transfer the obligations attaching to the Sabbath, divine worship and cessation from servile work, to the Sunday. This was done gradually. It was not until about the second century of the Christian era that the observance of the Sunday in place of the Sabbath became universal. Saint Thomas Aquinas teaches the observance of Sunday in the New Law succeeds to the observance of the Sabbath in the Old Law,
not by virtue of a divine precept, but from the authority of the Church and the custom of Christians. The introduction of this change by the Church must have had the sanction of Christ, Who is the Lord of the Sabbath, and Who promised to be "with" the Church even to the consummation of the world.
The Seventh Day Adventist tenet is an instance of individualism and private judgment against the custom of the whole Christian Church (though it is logical for those who maintain the "Bible and the Bible only" theory). They insist that divine worship and bodily rest must be observed on the seventh day of the week instead of the first. In this they agree with the Jews. In the Old Law the Sabbath was a figure of things to come, while in the New Law the Sunday is a symbol of the accomplishment of the prophecies in the Redeemer. By continuing the Sabbath observance, the Adventists, though they call themselves Christians, not only associate themselves with the Jews, who are still hoping for the Redeemer, but they also contradict the practice of the whole Christian Church. Is it not presumptuous for them to decide what the Apostles could not do? The Apostles were given the power to bind and loose, and their decisions were ratified in heaven (Matt. 18:18).
The sanctification of one day in the week is of divine law, but
the determination of the day in the New Law was left to the authority of the Church. Since the ceremonial and judicial precepts of the Old Law were abolished by the New Law,
the Church determined that the first day of the week was to be devoted to divine worship and bodily rest, in order to distinguish the true religion from the Mosaic, which was supplanted by Christianity.
