This week's post comes once again from J. G. Vos's exposition of the Larger Catechism; with the focus being on the change to the Sabbath to the first day of the week owing to Christ's resurrection:
... 9. Why was the Old Testament Sabbath the seventh day of the week? The Old Testament Sabbath was the seventh (last) day of the week because of God’s example and ordinance at the time of the creation (Gen. 2:1-3). Apart from providing an appointed day for rest and worship, the Sabbath served as a reminder of God’s work of creation. This truth of creation, of course, implies that all things, including human beings, are absolutely dependent on God for their very existence. It also implies that human beings are morally responsible to God for their lives. Thus the weekly Sabbath, commemorating the creation, was calculated to serve as a continually repeated reminder of man’s dependence on God and his moral accountability to God - which is to say that the Sabbath was calculated to serve as a constant reminder of the very foundations of religion and morality.
10. Why is the Christian Sabbath on the first day of the week? The Christian Sabbath, or the Lord’s Day is on the first day of the week in remembrance of Christ’s resurrection from the dead. Thus it may he said that the Old Testament Sabbath commemorated God’s original creation, while the Christian Sabbath in addition calls attention to God’s new creation, his great work of redemption in Jesus Christ.
11. Who changed the day of the Sabbath from the seventh to the first day of the week? Our Lord Jesus Christ, by the accomplishment of his great redemptive work, brought about the close of the Old Testament dispensation and the opening of the New Testament dispensation of the covenant of grace. The change from the seventh to the first day of the week is a part of this change of dispensation. It has been observed that our Saviour was crucified on the sixth day of the week, and buried on the evening of the sixth day, and remained in the tomb the whole of the seventh day, and arose from the dead on the first day of the week. Thus Christ buried the Old Testament seventh day Sabbath in the tomb with himself; and left it there, and when he arose he brought with him the New Testament Sabbath, which is to he observed on the first day of the week. ...
