Robert Barclay, the Celebrated Quaker.

We not seeing any ground in Scripture for it, cannot be so superstitious as to believe that either the Jewish Sabbath now continues, or that the first day of the week is the antitype thereof, or the true Christian Sabbath, which, with Calvin, we believe to have a more spiritual sense; and therefore we know no moral obligation, by the Fourth Commandment or elsewhere, to keep the first day of the week more than any other, or any holiness inherent in it.—An Apology for the True Christian Divinity, 1678.
