One Salvation
...In every Age of the Church, the Lord hath revealed so much supernatural truth as was for that age necessary unto salvation, his wayes he made known to Moses, Psal. 103:7. and his statutes to Israel, Deut. 4:6. Psal. 147:20. Heb. 1:1. Therefore that is an erroneous opinion, that before the Law written men were saved by the Law of nature, and in the time of the Law by the Law of Moses, and since in the time of the Gospel by the Word of grace.
