About this book

The Economy of the Covenants Between God and Man is Hermann Witsius's magnum opus and one of the most comprehensive treatments of covenant theology in the Reformed tradition. First published in 1677 and expanded through subsequent editions, it became a standard textbook in Reformed seminaries for over two centuries. Volume 1 establishes the theological foundations, beginning with a remarkable irenic preface addressed to the Dutch theological faculty, before moving into a systematic treatment of the divine covenants.

Witsius begins by carefully defining what a covenant is, tracing the Hebrew and Greek terminology through Scripture, examining the ancient ceremonies of covenant-making, and distinguishing between the various types of covenants God has made with humanity. He then develops his treatment of the covenant of works — the original arrangement between God and Adam — with exhaustive biblical detail, covering the nature of the Sabbath, the tree of life, the law written on the heart, and the conditions under which humanity was first placed.

What sets Witsius apart from other covenant theologians is his combination of rigorous scholarship with pastoral warmth and an unusually charitable spirit toward those with whom he disagrees. His opening address alone stands as one of the finest pleas for theological unity in the Reformed tradition. This modernized edition preserves the full depth of his theological argument while making his seventeenth-century prose accessible to today's readers.

A Pacific Address

To the highly respected, learned, and celebrated professors of divinity in the universities of the United Provinces of Holland; pastors of the Reformed churches; and zealous defenders of the faith once delivered to the saints.

The present age has produced so many books that the world is nearly exhausted by them, and the church certainly strains under their weight. This is especially striking given that the church has never flourished more than in those seasons when, in the pure simplicity of faith and love, and without any appetite for controversy, it fixed its attention on the teaching of our Lord alone and drew its truth from those writings that could make David wiser than all his teachers, and equip the man of God completely for every good work. It is genuinely difficult, in our time, to write anything that will satisfy readers. Learning is everywhere abundant, or at least the pretense of it is; attachment to long-held positions is stubborn; the study of narrow specialties is intense; and the judgments passed on other people's work are often uncharitable, a tendency that can affect even good people without their fully realizing it. Anyone who hopes, through writing, to satisfy the refined tastes of careful readers, or those engaged in a broader search for knowledge, seems to be overestimating his own abilities and misreading the spirit of the age.

I am well aware of my own limitations, and no one who has spent any real time in the world can remain ignorant of how it works. It therefore seems right to explain why I am presenting myself to the public again, and to lay out the purpose of the work I now offer to the churches.

And to whom, reverend and learned Sirs, should I offer these reasons if not to you, who are qualified to judge what I have written, and whose approval of my work I deeply desire, second only to God's and my own conscience? Let me state plainly at the outset: what has moved me to write is not some restless compulsion to put words on a page, nor a burning hunger for recognition, nor a jealous spirit, nor any contemptible desire to tear open wounds already inflicted on the churches. It is not the ugly satisfaction of smearing someone else's reputation by twisting what is genuinely sound, and it is certainly not the shameful ambition to start, fuel, or prolong conflict. Beyond my own word on the matter, the work itself, even on a casual reading, will clear me of any such motives.

Seeing the minds of sincere believers disturbed by the careless assertions of some writers, and by their unconventional interpretations of Scripture, was deeply troubling to me. The suspicions of others added to this concern, suspicions not always guided by charity, whatever role prudence may have played. Beyond this, the doctrine of the covenant of grace, which explains how sinners are reconciled to God, along with the varied ways that covenant has been administered throughout history, has been a source of painful controversy in the Netherlands. In fact, nearly every theological dispute currently in circulation, if we set aside the new methods of interpreting prophecy and the ideas borrowed from modern philosophy that are being unwisely imported into theology, can and should be traced back to this central doctrine.

For these reasons, I judged it the most pressing subject to address. I have handled it, however, in a way that remains consistent with the truths the churches have long received, and without the flippancy or harshness that the law of love forbids. With that in mind, I chose not to limit myself to bare polemical disputation, which is generally unproductive and, when stripped of its bitterness, tends to be entirely without elegance.

I chose to begin this subject from its very foundation, working to explain it as methodically and clearly as I could. Throughout, I have tried to illuminate the more difficult passages of Scripture, examine carefully the language the Holy Spirit uses, and connect everything to the practice of faith and godliness, and to the glory of God in Christ, so that my exposition might be both useful and engaging. Nothing proved more profitable and delightful to me personally, and nothing more effectively convinces the minds of others, than a clear and measured demonstration of truth to the conscience. Such a demonstration works by gradual and pleasing steps: it begins with plain, widely accepted truths, links them together carefully, and moves steadily toward the more difficult points, drawing the reader to agree with those points just as firmly as with the ones that were obvious from the start. And in doing so, it brings certain previously unknown truths before the innermost part of the soul, leaving it arrested in something close to wonder at the contemplation of God's remarkable perfections.

I found it absolutely necessary to engage with opposing viewpoints: those of the public adversaries of the Reformed churches, among whom I count first the Socinians and the Remonstrants, the Dutch Arminian party, who have corrupted the doctrine of God's covenants with their reckless interpretations; and those of certain brothers in the faith who have taken it upon themselves to construct new theological systems, nearly uprooting sound doctrine in the process. I like to think that no fair-minded critic could deny I have acted with honesty and restraint. I have framed each controversy accurately, never attributing to anyone a position he would not recognize as his own, and I have relied only on arguments that first satisfied my own conscience. If those arguments are not convincing on their own merits, I don't believe that adding more heat would make them any stronger. I was especially careful to treat the views of my fellow believers with generosity. I never went hunting for a careless word, a clumsy phrase, or an awkward expression just to score a point against them. It seemed far better to show how much the orthodox agree, and how the less careful expressions can be charitably read, reserving criticism only for those positions that are genuinely different. And those genuine differences, I dare say, will turn out to be fewer and less significant than is commonly assumed, provided we examine them without bias.

Even so, I could not simply ignore certain strange expressions, foreign interpretations, or contradictory claims; and I occasionally note the dangers some of them carry, though without any ill will toward their authors. For I will be honest: I share the view of those who believe the doctrine of the covenant has long rested on too solid a foundation in the churches to need new theoretical frameworks, and in those frameworks I cannot find the rigor or the usefulness that sound theology requires.

The idea of a threefold covenant of grace has been widely promoted: the first, under the promise, in which grace and freedom prevailed without the burden of an accusing law; the second, under the law, when the Old Testament era subjected the faithful to the rule of angels, the fear of death throughout their lives, and ultimately to the curse, denying the fathers any true or lasting blessings; the third, under the Gospel, when the godly began to be freed from the rule of angels, from the fear of temporal death, and from the curse that strict observance of the ceremonial law carried with it, and when they at last enjoyed true and lasting blessings: the circumcision of the heart, the law written within it, full and genuine forgiveness of sins, the spirit of adoption, and things of that kind.

This idea, I have to say, does not seem to me worthy of the enormous attention it has received in so many academic lectures, so many sermons, and so many books published in both Latin and our own language, as though the whole of theological learning depended on it. In the work that follows, I have shown that however these doctrines are explained, they are dreadful to even state aloud, and they cannot be defended without twisting Scripture.

Far more dangerous, in my view, are the opinions of certain scholars who are otherwise highly learned, yet deny that a covenant of works was ever made with Adam. They are reluctant to accept that the death threatened as the penalty for sin included any bodily death, and they deny that spiritual and heavenly blessings (the very blessings we now receive through Christ) were promised to Adam on the condition of perfect obedience.

By means of a stale and artificial distinction, they divide the sufferings of Christ into two categories: those that were painful and those that were judicial. They then argue that only the judicial sufferings, or as they sometimes soften the claim, primarily the judicial sufferings, were truly satisfactory. In doing so, they effectively exclude His anguish in the garden, the sentence pronounced against Him by both the Jewish council and the Roman governor, the wounds inflicted on His body by flogging, His nailing to the cursed cross, and finally death itself. On all of these matters, I have spoken my mind freely and honestly, as befits a defender of truth and an opponent of falsehood. That same honorable description was applied to the emperor Constantine IV by the Sixth Ecumenical Council, which convened at Constantinople (AD 681), and it is a standard that everyone in our calling should strive to deserve.

I have also noted some matters of lesser importance that seemed to lack solid scriptural grounding, or that were conceived less carefully than they should have been. This labor was not without its rewards. Amphilochius, the early church bishop, was rightly praised by Basil the church father for believing that no word used concerning God should pass without the most careful inquiry into its meaning. I have pursued this same standard, however, without bitterness or mockery: not to rebuke the authors themselves, but so that the diligent reader might benefit from seeing their errors identified, as Polibius somewhere puts it.

I hope the learned and fair-minded will not take it badly if (to borrow nearly the words Augustine uses when he expresses his disagreement with Cyprian) while I cannot reach their level of merit, while I acknowledge my own writings as inferior to many of theirs, while I admire their ingenuity, take delight in what they say, and hold their virtues in high regard, I still cannot agree with them on every point, but instead make use of the freedom to which our Lord has called us. This is especially true when they can see that I have gladly embraced their own brilliant insights: what they discovered through careful study of the original languages, what they skillfully recovered from the remains of previously unknown antiquity, what they confirmed with sound judgment or explained with clarity, and what I have commended warmly to the reader.

They will also find that wherever I consider them correct, however harshly others may judge them, I have defended them wholeheartedly and cleared away the charges of absurdity and novelty. I have done this so often and so carefully that some will no doubt say I have gone too far. But I cannot bring myself to regret having dealt so honestly with them. How could anyone have done otherwise, if he is not bound to any faction, not enslaved to his own preferences or anyone else's, but has devoted himself to truth alone and cares not who is speaking but what is being said? Whoever loves the peace of Jerusalem would rather see controversies reduced than multiplied, and will gladly learn that several things once treated as matters of dispute are, in fact, harmless or even beneficial.

All good people are rightly offended by the kind of intellectual recklessness that, in our day, launches dogmatic attacks against sound and established opinions, and that boldly offers interpretations of prophecy that are often more absurd than illuminating, dragging in whatever material suits the argument, even when that material contains nothing beyond the basic doctrines of our common faith and Christian conduct. This abuse does no small damage to public life and to the sacred work of ministry. It is no surprise, then, that the more passionate among us have responded to this recklessness with the sharp criticism it deserves, and perhaps with more force than was strictly necessary.

Even so, moderation should govern everything we do. I cannot endorse the approach of those who, while discussing points of disagreement, feel the need to catalog not merely dozens of controversies but hundreds of them, and who frequently bring a kind of cruel eloquence to bear on subjects that deserve far gentler treatment. Whether this style of disputation does anything to advance saving knowledge or build up the souls of believers, I will leave for others to judge. What I am certain of is this: the enemies of our church take great delight in it, and quietly rejoice that our internal disputes are as numerous and as heated as the disputes we carry on with them. And not so quietly, either, for they have never stopped throwing this charge in our faces, and they never will. It is a reproach that, I am sorry to say, is not easily answered.

How much better it would be if we devoted our greatest efforts to reducing, healing, and, if at all possible, ending every controversy among us. Make this your chief concern, reverend and learned sirs. The godly who grieve over the wounds in Joseph's house call for it; the churches entrusted to your care call for it; and Jesus himself, the king of truth and peace, calls for it and expects it from you.

They plead with you in the most earnest terms: "If therefore there be any consolation in Christ, if any comfort of love, if any fellowship of the Spirit, if any tenderness and mercies, fulfill my joy, fulfill the joy of all the saints, fulfill the joy of our Lord Jesus himself, that you may be like-minded, having the same love, being of one accord, of one mind." We have already seen more than enough quarrels, slanders, and suspicions; more than enough strife among brothers, which, I assure you, will give no one any real cause for triumph; more than enough internal divisions that are tearing us apart; and more than enough passion run to anger. From this point on, let the love of division, the hunger for dominance, and the use of divisive labels be driven from among us. Let all combative, mocking, and venomous writing be set aside, since it only fans the flames of harmful disputes.

But if we must write on these controversies, let us lay aside every corrupt disposition that distorts our thinking and misleads our readers. Let us fight with arguments, not insults, keeping in mind the words of Aristophanes: it is dishonorable, and entirely unworthy of poets, to rail against one another. How much less does it become Christians to do so. The streams of theology are pure; they rise only from the fountain of sacred learning and should never be polluted with the murky waters of ancient or modern philosophy. Let us avoid harsh and unusual expressions, and crude or reckless assertions, from which come "envy, strife, railings, and evil suspicions." The instruments of both covenants should be handled diligently by all, but with sacred reverence and humility. Let no one congratulate himself on his commentaries simply because they contain something new and unknown to those who came before him. Whoever believes he has discovered something better than the received opinion should offer it to the public with modesty, without belittling his brothers; not asserting or deciding rashly, but submitting his thoughts to the scrutiny of the learned and the judgment of the church; not forcing them on ordinary believers to the confusion of their minds; and not rushing to press them on impressionable young students, who are poorly equipped to judge such weighty matters. Nor should anyone reject a reading simply because it is new, provided it fits the meaning of the words, aligns with scriptural language, conforms to the analogy of faith, or respects the relationship the text bears to others. Cajetan, the Roman Catholic cardinal and theologian, whom our Chameir, the French Reformed theologian, commends, put it well on this point: "If a new sense of the text presents itself, though it differs from that of theologians in general, let the reader judge it for himself." And elsewhere he writes: "Let no one refuse to accept a new sense of sacred Scripture simply because it differs from what the ancients gave; for God has not bound Himself to the truth of their interpretations." Let the depths of prophecy also be searched diligently, but reverently, without twisting the Scriptures, and without violating the boundaries it has pleased God to set around them as a guard against unaided human insight; lest the one who attempts to peer into the majesty be overwhelmed by the glory.

Let no one, regardless of how great their reputation, use their authority to bind the free consciences of believers. As Clement of Rome once said, let the truth be drawn from the Scriptures themselves. In religious matters, everything should stand or fall by Scripture alone, and all controversies should be settled by it. The ancient councils were guided by the sacred and undefiled Gospels of our Lord Jesus Christ. That said, no one should carelessly use this principle as an excuse to withhold agreement from expressions that are drawn directly from God's Word, that align with Scripture, that serve as bonds of church unity, marks of orthodoxy, barriers against heresy, and boundaries for undisciplined minds. To treat such expressions as though they were remnants of the Tower of Babel, forcing people to think and speak alike in religion, would be a serious mistake.

No one should single out one modern theologian as their personal guide, receiving everything that person says as if it were divine revelation, treating him as a new teacher and light to the world (as the ancients said of Basil), and regarding everyone else by comparison as children or dwarfs. This is especially misguided when the man himself likely insists that he never intended to introduce anything new or to become the founder of a sect. On the other hand, no one should dismiss such a person as though nothing true, nothing good, and nothing useful for understanding Scripture could be learned from him. God does not move devout people to search the Scriptures night and day without opening to them something of the treasures of His sacred wisdom.

Let us proclaim the good news of the Gospel, celebrate it with the church, and make the most of it in our own lives. No one who has generally expressed the truth with skill and eloquence should be harshly condemned for a careless word or a clumsy phrase that slipped into their writing. Poison does not hide in syllables, nor does truth live in sound alone but in intention; and godliness is not found in the ringing of brass but in the meaning behind the words. Even so, let us all strive to express ourselves as precisely as we can, and resist the urge to defend what we or our friends have said carelessly, lest others hold it against us. Instead, as far as honesty, truth, charity, and the judgment of thoughtful people will allow, let us set aside, retract, or correct our mistakes. This is exactly what many great thinkers, both ancient and modern, have done, and it has served their reputations well.

Let none of our fellow believers be branded as heretics on the basis of what someone else claims logically follows from their words, when they themselves reject and abhor that conclusion. Solid learning, conduct that reflects genuine Christian holiness, a peaceable spirit, and a faithful and quiet fulfillment of our responsibilities will earn far more respect than reckless, heated zeal or the forceful outbursts of a passionate temperament. Such outbursts are designed, more often than not, to elevate our own status and sense of importance, even when the cause of God is offered as the justification for them.

Let some freedom also be given to scholars in how they interpret Scripture passages, in the arguments they choose to defend the faith we hold in common, in the terms and language they use, and in how they resolve difficult questions (for in our present state of limited understanding, we cannot expect everyone to think and speak identically). But let this freedom stay within the boundaries of humility, wisdom, and love, so that it does not decay into arrogant carelessness and turn our Zion into a Babel.

These, reverend and learned gentlemen, are my deepest hopes; these are my convictions, which I commend to your wisdom, faith, and devotion. I commend you and your faithful labors to the grace of our great God and Savior Jesus Christ, who can equip you fully for every good work, to do His will, working within you what is pleasing in His sight; and who, when you have at last fought the good fight of faith to its happy conclusion, will crown you with an everlasting glory. This has long been, and remains today, the most earnest prayer of, reverend and learned gentlemen, your fellow laborer and servant in the Lord,

Utrecht, Oct. 20, 1693.

Chapter 1: On the Divine Covenants in General

1. Whoever sets out to discuss the subject and purpose of the Divine Covenants, by which eternal salvation is promised to humanity on conditions equally worthy of God and of rational creatures, must above all maintain a sacred and unwavering respect for the heavenly Scriptures. He must never allow prejudice or passion to introduce anything he is not firmly convinced is actually contained in the records that present these covenants to the world. Consider this: Zaleucus, the ancient Greek lawgiver, required that anyone who disputed the interpretation of his laws had to stand before an assembly of a thousand people with a noose around their neck, and whichever party was found to have twisted the meaning of the law would be hanged on the spot, as the Greek historian Polybius records in his History, book 12, chapter 7. Similarly, according to Josephus, the Jewish historian, in his Antiquities, book 13, chapter 6, when Jews and Samaritans in Egypt each argued for the legitimacy of their own temple before the king and his court, both sides agreed that whichever party lost the debate would be put to death. If such severe penalties applied to those who distorted merely human laws, then surely far greater danger awaits anyone who dares to corrupt the sacred mysteries of the Divine Covenants by recklessly twisting their meaning. Our Lord himself made this plain when He declared that "whoever breaks one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven" (Matt 5:19). It is therefore with something like holy reverence that I take up this work, praying that God would strip away every prejudice from my mind, so that I might approach the Holy Scriptures as a teachable student, and share with my brothers, in a spirit of humility, what I believe I have learned from them. My hope is that this modest effort might help reduce the number of disputes and bring greater clarity to the truth, for nothing ought to be valued more highly than that.

2. Since it's through words, especially the words of those languages in which God chose to reveal His sacred mysteries to humanity, that we can hope to understand these things, it's worth taking a careful look at both the Hebrew word berit and the Greek diatheke, which the Holy Spirit uses on this subject. We should begin with the true etymology of the Hebrew word before moving on to its various meanings. Scholars are not in agreement on this point. Some trace it back to bara, which in the Piel form means "to cut down," because, as we will see shortly, covenants were formally ratified by cutting or dividing animals in two. It can also be derived from the same root in a quite different sense: since bara properly means "to create," it can also carry the metaphorical meaning of "to ordain" or "to arrange," which is precisely the meaning of the Greek diatithesthai. This is why Hellenistic Jews use the word ktizein in this context. Peter certainly uses it in this sense when he calls the authority appointed by human beings and for human purposes anthropine ktisis, "the ordinance of man" (1 Pet 2:13), a point on which Grotius, I think, has made a learned observation in his notes on the title of the New Testament. Others prefer to trace berit back to barah, following the same pattern as shevit from shavah, which means, among other things, "to choose." And indeed, covenants, especially those of friendship, involve a choice: a choice of the persons between whom the covenant is made, of the matters it covers, and of the conditions on which it is entered into. This is not an unreasonable observation.

3. The word berit is used in Scripture in a variety of ways, sometimes in an improper sense and sometimes in a proper one. In its improper sense, it refers to the following things.

First, a covenant can refer to an immutable ordinance established concerning a particular matter. In this sense, God speaks of "his covenant of the day, and his covenant of the night" (Jer 33:20), meaning the fixed ordinance governing the unbroken alternation of day and night. In Jer 31:36, this is called choq, meaning a statute, something set and bounded, to which nothing may be added or removed. This sense also carries within it the idea of a testament, or a final, irrevocable will. So God declared in Num 18:19, "I have given thee and thy sons, and thy daughters with thee" berit melach olam, "by a statute for ever, it is a covenant of salt for ever." This observation helps us understand the covenant of grace more fully, since the Apostle presents it under the image of a testament whose execution depends on the death of the testator (Heb 9:15-17). Both the Hebrew berit and the Greek diatheke point us in this direction. Second, a covenant can refer to a firm and binding promise, even one that is not mutual in nature: "Behold I make a covenant; before all thy people I will do marvels" (Exod 34:10); and "this is my covenant with them, my spirit shall not depart from them" (Isa 59:21). Third, it can also signify a precept, so that to cut or make a covenant means to issue a command: "I made a covenant with your fathers, saying, at the end of seven years let ye go every man his brother" (Jer 34:13-14). This clarifies in what sense the Decalogue is called God's covenant. In its proper sense, however, a covenant refers to a mutual agreement between two parties concerning some matter. This is the kind of covenant made between Abraham, Mamre, Eshcol, and Aner, who are called ba'ale berit avram, "confederate with Abraham" (Gen 14:13). The same applies to the covenant between Isaac and Abimelech (Gen 26:28-29), and between Jonathan and David (1 Sam 18:3). It is also this kind of covenant, between God and man, that we are now about to examine.

4. The Greek word diatheke is equally ambiguous. Both in its singular and plural forms, it very often means a testament or will, as Budaeus, the French classical scholar, demonstrates in his Commentarii Linguae Graecae by drawing on Isocrates, Aeschines, Demosthenes, and others. We noted earlier that the Apostle uses it in this sense in Heb 9:15. Sometimes it also means a law, understood as a rule for living. According to Grotius, the Orphics and Pythagoreans used the plural diathekae to describe the rules of conduct they prescribed to their students. It also frequently carries the sense of an engagement or agreement, which is why Hesychius, the ancient Greek lexicographer, glosses it with synomasia, meaning confederacy. Each of these meanings will prove useful as this work progresses.

5. The Hebrew expression for making a covenant is karat berit, literally to strike a covenant, which parallels the Greek and Latin idioms ferire, icere, percutere foedus, all of which carry the same sense of striking or cutting a deal.

This ceremony almost certainly originated from the ancient practice of slaying and dividing animals as a way of ratifying covenants. We see very early traces of this rite in Gen 15:9-10. Whether God first commanded it on that occasion or whether it was drawn from an already existing custom is unclear. Particularly striking is what Polybius records in book 4, p. 398, concerning the Cynæthenses: "over the slaughtered victims they took a solemn oath, and plighted faith to each other" (epi ton sphagion tas horkous kai tas pisteis edidosan allelois). This phrasing closely parallels the language God uses in Ps 50:5, "those that have made a covenant with me by sacrifice" (korete beriti, ale zavach). It was also customary for the parties involved to walk between the two halves of the divided animal, as we see in Jer 34:18. Anyone wishing to explore this rite further should consult Grotius on Matt 26:28, Bochart, the French Protestant scholar, in his Hierozoicon (book 2, ch. 33, p. 325), and Ouwen's Theologum (book 3, ch. 1). There was likewise a custom of sealing agreements and compacts with solemn feasts, and Scripture offers clear examples of this. When Isaac made a covenant with Abimelech, he is said to have prepared a great feast and eaten with them (Gen 26:30). His son Jacob did the same after making a covenant with Laban (Gen 31:54). A similar covenant feast appears in 2 Sam 3:20, which describes the feast David held for Abner and his attendants when they came to make a covenant with him on behalf of the people. That this practice was equally common among the pagans is demonstrated by the learned Stuckius, the Swiss classical scholar, in his Antiquitates convivales (book 1, ch. 40).

6. These rituals were not without meaning. The cutting of the animals in two signified that covenant-breakers and those who swore falsely would be cut apart in the same way by God's judgment. This is what God declares: "And I will give the men that have broken my covenant, who have not kept the words of the covenant they made before me, when they cut the calf in two and passed between its parts. I will give them into the hands of their enemies, and their dead bodies will be food for the birds of the sky and the beasts of the earth" (Jer 34:18-20). See also 1 Sam 11:7. An ancient form of this kind of curse survives in Livy, Book 1: "The Roman people will not be the first to break these terms; but if they should break them openly and through treachery, then on that day, O Jupiter, strike the Roman people as I now strike this hog, and let the blow be heavier as your power is greater." The ceremony of the parties passing between the divided pieces signified that they were now bound together by the most solemn religious ties and by oath, forming a single body, as Vatablus observed on Gen 15:10. The covenant feasts that accompanied these rites were expressions of genuine and lasting friendship.

7. But when God chose to use these rites, or similar ones, in the formal ceremonies of His covenants with humanity, their meaning became far more noble and divine. Those who entered into covenant with God through sacrifice were not merely acknowledging that they deserved punishment if they wickedly abandoned Him and despised His covenant. God was also signifying something deeper: that the entire stability of the covenant of grace rests on the sacrifice of Christ, and that the soul and body of Christ would one day be violently torn apart. "All the promises of God in him are yes, and in him amen" (2 Cor 1:20). "His blood is the blood of the New Testament" (Matt 26:28), in a far more excellent sense than the blood with which Moses sprinkled both the altar and the people when they entered into covenant (Exod 24:8). Those sacred meals to which the covenant people were admitted in the presence of the Lord, and especially the one instituted by the Lord Jesus under the New Testament, most powerfully seal and confirm the intimate communion and fellowship that exists between Christ and His people.

8. Some scholars use this ritual to explain a phrase found in Num 18:19 and 2 Chr 14:5: the "covenant of salt," meaning a covenant of friendship that is stable and permanent. As Rivet notes in his commentary on Genesis (Exercit. 136), it seems to have been called this "because salt was commonly used in sacrifices, signifying that the covenant was ratified through the customary rites." Alternatively, one might see a reference to salt's natural firmness, its ability to resist decay and corruption, and its power to preserve things and, in a sense, make them last indefinitely. For this reason, Lot's wife is thought to have been turned into a pillar of salt: not so much, as Augustine observes, to season our food, but to serve as a lasting and permanent monument to divine judgment. After all, not all salt dissolves easily. Pliny records that some Arabs build walls and houses from blocks of salt and cement them together with water (Nat. Hist. 31.7).

9. Having made these general observations about technical terms, let us now turn to the heart of the matter: the nature of God's covenant with humanity. I define it as follows. A covenant of God with man is an agreement between God and humanity concerning the way to obtain complete and perfect happiness, together with a warning of eternal destruction for anyone who despises the happiness offered through that covenant.

10. The covenant, on God's part, contains three things in general. First, a promise of complete happiness in eternal life. Second, the designation and prescription of the condition by fulfilling which a person acquires a right to that promise. Third, a penal sanction against those who fail to meet the prescribed condition. All three of these concern the whole person, or holoklēros (complete and entire), as Paul phrases it, consisting of both soul and body. God's promise of happiness extends to each part; He requires the sanctification of each part, and He threatens each part with destruction. In this way, the covenant causes God to be glorified in the whole person.
