Note 20b — THE DIVINE AND PERPETUAL OBLIGATION OF THE SABBATH.
Reading edition
The fourth commandment is in its nature partly moral and partly positive. Reason teaches the duty of devoting a portion of our time to the worship of God. Revelation determines the amount by a positive enactment. Now, it is very remarkable, that while all the other sabbatical institutions (which are peculiar to the Jews) are omitted in the moral law and inserted in the ceremonial law, that of the seventh day alone stands in the decalogue. Is not this a tacit indication of its moral character?
