Thesis 191.

[ 191] The light of nature in the Gentiles, especially in matters of the first Table, was very imperfect, dim, and corrupt; Hence it is that we cannot expect to ••inde any perfect light of nature in matters of the Sabbath; some glimmerings and dark practices herein are sufficient to prove that this Law is naturall, although the exact proportion of time for rest should not or could not by any reasoning of corrupt nature be perfectly found out; their observation of holy daies and festivals did argue some imperfect light of nature left, con∣cerning the Sabbath, which once nature had more perfectly, as old walls and rubbish doe argue old and great buildings in former times; but suppose they could not finde out exactly

the seventh part of time, and so dedicate it to God for his Sabbath; yet the want of such light argues only the want of perfection of the light of nature, which we should not ex∣pect to finde in the present light of nature in matters of the first Table, and in this of the Sabbath; and therefore tis no argument to prove the Sabbath not to be of the Law of na∣ture, because the perfect knowled of the exact time thereof is not left in corrupt nature now.
