Hence, if any one desires to make a necessary command out of the Sabbath, as a work required of God, he must observe Saturday and not Sunday, for Saturday was enjoined upon the Jews, and not Sunday.

But Christians have hitherto observed Sunday, and not Saturday, because on that day Christ, arose.

Now this is a certain evidence to us that the Sabbath, yea the entire Moses (Mosaic dispensation) no longer concerns us, else we would be under obligation to observe Saturday.

This is a great and strong proof that the Sabbath is revoked; for throughout the whole New Testament we find no place in which the observance of the Sabbath in enjoined upon Christians." "But why (continues Luther,) is Sunday observed among Christians?
Although, _all days are free and one day is like another_, it is still necessary and good, yea, very necessary, that some one day be observed, _whether it be Sabbath, Sunday or any other day_.

For God designs to lead the world decently, and govern it peaceably; therefore he gave six days for work, but on the seventh day, servants, hirelings, and laborers of every kind, yea, even horses and oxen and other laboring animals shall have rest, as this precept requires, in order that they may be refreshed by rest.
