Westminster Confession Of Faith – Lord’s Day 30
Chapter 19 – Of the Law of God (Paragraphs 1-2)
I. God gave to Adam a law, as a covenant of works, by which he bound him and all his posterity to personal, entire, exact, and perpetual obedience; promised life upon the fulfilling, and threatened death upon the breach of it; and endued him with power and ability to keep it.
II. This law, after his Fall, continued to be a perfect rule of righteousness; and, as such, was delivered by God upon mount Sinai in ten commandments, and written in two tables; the first four commandments containing our duty toward God, and the other six our duty to man.
