“Stated simply, the Westminster Confession and the divines that composed the document accept natural theology to a greater degree than present-day Reformed theologians.”
– Fesko, J.V.; Richard, Guy – “Natural Theology and the Westminster Confession of Faith” in The Westminster Confession into the 21st Century, vol. 3 Buy 2009, p. 224-5
The Standards use the idea of natural law primarily in relation to knowledge and ethics. According to the Standards there are specific things that can be known and are of binding ethical force which we learn from nature. The divines also founded certain theological arguments upon the nature of things, arguing for and against certain views of Christ’s person and the sacraments (for instance) based on what is in accordance with their nature or against their natures.
It should be noted that the various phrases in the standards ‘light of nature’, ‘law of nature’, ‘contrary to nature’, ‘the nature of’, etc., are used in a variety of ways and senses, which should be determined from the specific context, the overall theology of the Standards, and the larger thought of the puritans of the mid-1600’s.
The Westminster Confession
Ch. 1, Of the Holy Scripture
I. Although the light of nature, and the works of creation and providence do so far manifest the goodness, wisdom, and power of God, as to leave men unexcusable; yet are they not sufficient to give that knowledge of God, and of His will, which is necessary unto salvation.
VI… there are some circumstances concerning the worship of God, and government of the Church, common to human actions and societies, which are to be ordered by the light of nature, and Christian prudence, according to the general rules of the Word, which are always to be observed.
Ch. 5, Of Providence
II. Although, in relation to the foreknowledge and decree of God, the first Cause, all things come to pass immutably, and infallibly; yet, by the same providence, He orders them to fall out, according to the nature of second causes, either necessarily, freely, or contingently.
Ch. 6, Of the Fall of Man, of Sin, and the Punishment Thereof
VI. Every sin, both original and actual, being a transgression of the righteous law of God, and contrary thereunto, does in its own nature, bring guilt upon the sinner, whereby he is bound over to the wrath of God, and curse of the law, and so made subject to death, with all miseries spiritual, temporal, and eternal.
Ch. 8, of Christ the Mediator
VII. Christ, in the work of mediation, acts according to both natures, by each nature doing that which is proper to itself; yet, by reason of the unity of the person, that which is proper to one nature is sometimes in Scripture attributed to the person denominated by the other nature.
Ch. 10, Of Effectual Calling
IV… much less can men, not professing the Christian religion, be saved in any other way whatsoever, be they never so diligent to frame their lives according to the light of nature, and the laws of that religion they do profess. And to assert and maintain that they may, is very pernicious, and to be detested.
Ch. 20, Of Christian Liberty and Liberty of Conscience
IV. And because the powers which God has ordained, and the liberty which Christ has purchased are not intended by God to destroy, but mutually to uphold and preserve one another, they who, upon pretence of Christian liberty, shall oppose any lawful power, or the lawful exercise of it, whether it be civil or ecclesiastical, resist the ordinance of God. And, for their publishing of such opinions, or maintaining of such practices, as are contrary to the light of nature, or to the known principles of Christianity (whether concerning faith, worship, or conversation), or to the power of godliness; or, such erroneous opinions or practices, as either in their own nature, or in the manner of publishing or maintaining them, are destructive to the external peace and order which Christ has established in the Church, they may lawfully be called to account, and proceeded against, by the censures of the Church, and by the power of the civil magistrate.
Ch. 21, of Religious Worship and the Sabbath Day
I. The light of nature shows that there is a God, who has lordship and sovereignty over all, is good, and does good unto all, and is therefore to be feared, loved, praised, called upon, trusted in, and served, with all the heart, and with all the soul, and with all the might. But the acceptable way of worshipping the true God is instituted by Himself, and so limited by His own revealed will, that He may not be worshipped according to the imaginations and devices of men, or the suggestions of Satan, under any visible representation, or any other way not prescribed in the holy Scripture.
VII. As it is the law of nature, that, in general, a due proportion of time be set apart for the worship of God; so, in His Word, by a positive, moral, and perpetual commandment binding all men in all ages, He has particularly appointed one day in seven, for a Sabbath, to be kept holy unto him: which, from the beginning of the world to the resurrection of Christ, was the last day of the week: and, from the resurrection of Christ, was changed into the first day of the week, which, in Scripture, is called the Lord’s Day, and is to be continued to the end of the world, as the Christian Sabbath.
Ch. 29, of the Lord’s Supper
IV. Private masses, or receiving this sacrament by a priest, or any other alone; as likewise, the denial of the cup to the people, worshipping the elements, the lifting them up, or carrying them about, for adoration, and the reserving them for any pretended religious use; are all contrary to the nature of this sacrament, and to the institution of Christ.
VI. That doctrine which maintains a change of the substance of bread and wine, into the substance of Christ’s body and blood (commonly called transubstantiation) by consecration of a priest, or by any other way, is repugnant, not to Scripture alone, but even to common sense, and reason; overthrows the nature of the sacrament, and has been, and is, the cause of manifold superstitions; yes, of gross idolatries.
Ch. 30, of Church Censures
IV. For the better attaining of these ends, the officers of the Church are to proceed by admonition; suspension from the sacrament of the Lord’s Supper for a season; and by excommunication from the Church; according to the nature of the crime, and demerit of the person.
The Larger Catechism
Q. 2. How doth it appear that there is a God?
A. The very light of nature in man, and the works of God, declare plainly that there is a God; but his word and Spirit only do sufficiently and effectually reveal him unto men for their salvation.
Q. 60. Can they who have never heard the gospel, and so know not Jesus Christ, nor believe in him, be saved by their living according to the light of nature?
A. They who, having never heard the gospel, know not Jesus Christ, and believe not in him, cannot be saved, be they never so diligent to frame their lives according to the light of nature, or the laws of that religion which they profess; neither is there salvation in any other, but in Christ alone, who is the Savior only of his body the church.
Q. 121. Why is the word Remember set in the beginning of the fourth commandment?
A. The word Remember is set in the beginning of the fourth commandment, partly, because of the great benefit of remembering it, we being thereby helped in our preparation to keep it, and, in keeping it, better to keep all the rest of the commandments, and to continue a thankful remembrance of the two great benefits of creation and redemption, which contain a short abridgment of religion; and partly, because we are very ready to forget it, for that there is less light of nature for it, and yet it restraineth our natural liberty in things at other times lawful; that it cometh but once in seven days, and many worldly businesses come between, and too often take off our minds from thinking of it, either to prepare for it, or to sanctify it; and that Satan with his instruments much labor to blot out the glory, and even the memory of it, to bring in all irreligion and impiety.
Q. 127. What is the honor that inferiors owe to their superiors?
A. The honor which inferiors owe to their superiors is, all due reverence in heart, word, and behavior; prayer and thanksgiving for them; imitation of their virtues and graces; willing obedience to their lawful commands and counsels; due submission to their corrections; fidelity to, defense, and maintenance of their persons and authority, according to their several ranks, and the nature of their places; bearing with their infirmities, and covering them in love, that so they may be an honor to them and to their government.
Q. 139. What are the sins forbidden in the seventh commandment?
A. The sins forbidden in the seventh commandment, besides the neglect of the duties required, are, adultery, fornication, rape, incest, sodomy, and all unnatural lusts; all unclean imaginations, thoughts, purposes, and affections; all corrupt or filthy communications…
Q. 151. What are those aggravations that make some sins more heinous than others?
A. Sins receive their aggravations,
3. From the nature and quality of the offence: if it be against the express letter of the law, break many commandments, contain in it many sins: if not only conceived in the heart, but breaks forth in words and actions, scandalize others, and admit of no reparation: if against means, mercies, judgments, light of nature, conviction of conscience, public or private admonition, censures of the church, civil punishments; and our prayers, purposes, promises, vows, covenants, and engagements to God or men…
Q. 167. How is baptism to be improved by us?
A. The needful but much neglected duty of improving our baptism, is to be performed by us all our life long, especially in the time of temptation, and when we are present at the administration of it to others; by serious and thankful consideration of the nature of it, and of the ends for which Christ instituted it, the privileges and benefits conferred and sealed thereby, and our solemn vow made therein…
The Westminster Directory of Public Worship
Of the Preaching of the Word
In the use of instruction or information in the knowledge of some truth, which is a consequence from his doctrine, he [the minister] may (when convenient) confirm it by a few firm arguments from the text in hand, and other places of scripture, or from the nature of that common-place in divinity, whereof that truth is a branch.
In dehortation, reprehension, and publick admonition, (which require special wisdom,) let him [the minister], as there shall be cause, not only discover the nature and greatness of the sin, with the misery attending it, but also shew the danger his hearers are in to be overtaken and surprised by it, together with the remedies and best way to avoid it.
Concerning Public Solemn Fasting
A religious fast requires total abstinence, not only from all food, (unless bodily weakness do manifestly disable from holding out till the fast be ended, in which case somewhat may be taken, yet very sparingly, to support nature, when ready to faint,) but also from all worldly labour, discourses, and thoughts, and from all bodily delights, and such like, (although at other times lawful,) rich apparel, ornaments, and such like, during the fast; and much more from whatever is in the nature or use scandalous and offensive, as gaudish attire, lascivious habits and gestures, and other vanities of either sex; which we recommend to all ministers, in their places, diligently and zealously to reprove, as at other times, so especially at a fast, without respect of persons, as there shall be occasion.
The Form of Presbyterial Church Government
The Rules for Examination [of those on trial for ordination] are these:
(2.) He shall be examined touching his skill in the original tongues, and his trial to be made by reading the Hebrew and Greek Testaments, and rendering some portion of some into Latin; and if he be defective in them, enquiry shall be made more strictly after his other learning, and whether he hath skill in logic and philosophy.
