WCF 19.1–19.7

Of the Law of God

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.

Of the Law of God

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 four first commandments containing our duty towards God; and the other six our duty to man.

Of the Law of God

Beside this law, commonly called moral, God was pleased to give to the people of Israel, as a church under age, ceremonial laws, containing several typical ordinances, partly of worship, prefiguring Christ, His graces, actions, sufferings, and benefits; and partly holding forth divers instructions of moral duties. All which ceremonial laws are now abrogated, under the new testament.

Of the Law of God

To them also, as a body politic, He gave sundry judicial laws, which expired together with the State of that people; not obliging any other now, further than the general equity thereof may require.

Of the Law of God

The moral law doth for ever bind all, as well justified persons as others, to the obedience thereof; and that, not only in regard of the matter contained in it, but also in respect of the authority of God the Creator, who gave it: neither doth Christ, in the Gospel, any way dissolve, but much strengthen this obligation.

Of the Law of God

Although true believers be not under the law, as a covenant of works, to be thereby justified, or condemned; yet is it of great use to them, as well as to others; in that, as a rule of life informing them of the will of God, and their duty, it directs, and binds them to walk accordingly; discovering also the sinful pollutions of their nature, hearts, and lives; so as, examining themselves thereby, they may come to further conviction of, humiliation for, and hatred against sin; together with a clearer sight of the need they have of Christ, and the perfection of His obedience. It is likewise of use to the regenerate, to restrain their corruptions, in that it forbids sin: and the threatenings of it serve to show what even their sins deserve; and what afflictions, in this life, they may expect for them, although freed from the curse thereof threatened in the law. The promises of it, in like manner, show them God’s approbation of obedience, and what blessings they may expect upon the performance thereof; although not as due to them by the law, as a covenant of works. So as, a man’s doing good, and refraining from evil, because the law encourageth to the one and deterreth from the other, is no evidence of his being under the law; and not under grace.

Of the Law of God

Neither are the forementioned uses of the law contrary to the grace of the Gospel, but do sweetly comply with it; the Spirit of Christ subduing and enabling the will of man to do that, freely and cheerfully, which the will of God, revealed in the law, requireth to be done.

WLC Q91–99

Q91. What is the duty which God requireth of man?

A. The duty which God requireth of man, is obedience to his revealed will.

Q92. What did God at first reveal unto man as the rule of his obedience?

A. The rule of obedience revealed to Adam in the estate of innocence, and to all mankind in him, besides a special command not to eat of the fruit of the tree of the knowledge of good and evil, was the moral law.

Q93. What is the moral law?

A. The moral law is the declaration of the will of God to mankind, directing and binding everyone to personal, perfect, and perpetual conformity and obedience thereunto, in the frame and disposition of the whole man, soul and body, and in performance of all those duties of holiness and righteousness which he oweth to God and man: promising life upon the fulfilling, and threatening death upon the breach of it.

Q94. Is there any use of the moral law to man since the fall?

A. Although no man, since the fall, can attain to righteousness and life by the moral law; yet there is great use thereof, as well common to all men, as peculiar either to the unregenerate, or the regenerate.

Q95. Of what use is the moral law to all men?

A. The moral law is of use to all men, to inform them of the holy nature and will of God, and of their duty, binding them to walk accordingly; to convince them of their disability to keep it, and of the sinful pollution of their nature, hearts, and lives; to humble them in the sense of their sin and misery, and thereby help them to a clearer sight of the need they have of Christ, and of the perfection of his obedience.

Q96. What particular use is there of the moral law to unregenerate men?

A. The moral law is of use to unregenerate men, to awaken their consciences to flee from wrath to come, and to drive them to Christ; or, upon their continuance in the estate and way of sin, to leave them inexcusable, and under the curse thereof.

Q97. What special use is there of the moral law to the regenerate?

A. Although they that are regenerate, and believe in Christ, be delivered from the moral law as a covenant of works, so as thereby they are neither justified nor condemned; yet, besides the general uses thereof common to them with all men, it is of special use, to show them how much they are bound to Christ for his fulfilling it, and enduring the curse thereof in their stead, and for their good; and thereby to provoke them to more thankfulness, and to express the same in their greater care to conform themselves thereunto as the rule of their obedience.

Q98. Where is the moral law summarily comprehended?

A. The moral law is summarily comprehended in the ten commandments, which were delivered by the voice of God upon mount Sinai, and written by him in two tables of stone; and are recorded in the twentieth chapter of Exodus. The four first commandments containing our duty to God, and the other six our duty to man.

Q99. What rules are to be observed for the right understanding of the ten commandments?

A. For the right understanding of the ten commandments, these rules are to be observed: 1. That the law is perfect, and bindeth everyone to full conformity in the whole man unto the righteousness thereof, and unto entire obedience forever; so as to require the utmost perfection of every duty, and to forbid the least degree of every sin. 2. That it is spiritual, and so reaches the understanding, will, affections, and all other powers of the soul; as well as words, works, and gestures. 3. That one and the same thing, in divers respects, is required or forbidden in several commandments. 4. That as, where a duty is commanded, the contrary sin is forbidden; and, where a sin is forbidden, the contrary duty is commanded: so, where a promise is annexed, the contrary threatening is included; and, where a threatening is annexed, the contrary promise is included. 5. That what God forbids, is at no time to be done; What he commands, is always our duty; and yet every particular duty is not to be done at all times. 6. That under one sin or duty, all of the same kind are forbidden or commanded; together with all the causes, means, occasions, and appearances thereof, and provocations thereunto. 7. That what is forbidden or commanded to ourselves, we are bound, according to our places, to endeavor that it may be avoided or performed by others, according to the duty of their places. 8. That in what is commanded to others, we are bound, according to our places and callings, to be helpful to them; and to take heed of partaking with others in: What is forbidden them.
