We are not related to the law directly as it were, or the law in isolation as bare commandments. The relationship is dependent on and the new fruit of our prior relationship to Christ. In simple terms, just as Adam received the law from the Father, from whose hand it should never have been abstracted (as it was by the Serpent and then by Eve), so the new-covenant believer never looks at the law without understanding that his relationship to it is the fruit of his union with Christ.

Antinomianism takes various forms. People do not always fit neatly into our categorizations, nor do they necessarily hold all the logical implications of their presuppositions. Here we are using “antinomianism” in the theological sense: rejecting the obligatory (“binding on the conscience”) nature of the Decalogue for those who are in Christ. Antinomianism, it was widely assumed in the eighteenth century, is essentially a failure to understand and appreciate the place of the law of God in the Christian life. But just as there is more to legalism than first meets the eye, the same is true of antinomianism.

Opposites Attract?

Perhaps the greatest misstep in thinking about antinomianism is to think of it simpliciter as the opposite of legalism.

It would be an interesting experiment for a budding doctoral student in psychology to create a word-association test for Christians. It might include:

• Old Testament: Anticipated answer → New Testament
• Sin: Anticipated answer → Grace
• David: Anticipated answer → Goliath
• Jerusalem: Anticipated answer → Babylon
• Antinomianism: Anticipated answer → ?

Would it be fair to assume that the instinctive response there at the end would be “Legalism”?

Is the “correct answer” really “Legalism”? It might be the right answer at the level of common usage, but it would be unsatisfactory from the standpoint of theology, for antinomianism and legalism are not so much antithetical to each other as they are both antithetical to grace. This is why Scripture never prescribes one as the antidote for the other. Rather grace, God’s grace in Christ in our union with Christ, is the antidote to both.

This is an observation of major significance, for some of the most influential antinomians in church history acknowledged they were on a flight from the discovery of their own legalism.

According to John Gill, the first biographer of Tobias Crisp, one of the father figures of English antinomianism: “He set out first in the legal way of preaching in which he was exceeding jealous.”

Benjamin Brook sets this in a larger context:

Persons who have embraced sentiments which afterwards appear to them erroneous, often think they can never remove too far from them; and the more remote they go from their former opinions the nearer they come to the truth. This was unhappily the case with Dr. Crisp. His ideas of the grace of Christ had been exceedingly low, and he had imbibed sentiments which produced in him a legal and self-righteous spirit. Shocked at the recollection of his former views and conduct, he seems to have imagined that he could never go far enough from them.

But Crisp, in keeping with others, took the wrong medicine.

The antinomian is by nature a person with a legalistic heart. He or she becomes an antinomian in reaction. But this implies only a different view of law, not a more biblical one.

Richard Baxter’s comments are therefore insightful:

Antinomianism rose among us from an obscure Preaching of Evangelical Grace, and insisting too much on tears and terrors.

The whole scale removal of the law seems to provide a refuge. But the problem is not with the law, but with the heart—and this remains unchanged. Thinking that his perspective is now the antithesis of legalism, the antinomian has written an inappropriate spiritual prescription. His sickness is not fully cured. Indeed the root cause of his disease has been masked rather than exposed and cured.

There is only one genuine cure for legalism. It is the same medicine the gospel prescribes for antinomianism: understanding and tasting union with Jesus Christ Himself. This leads to a new love for and obedience to the law of God, which he now mediates to us in the gospel. This alone breaks the bonds of both legalism (the law is no longer divorced from the person of Christ) and antinomianism (we are not divorced from the law, which now comes to us from the hand of Christ and in the empowerment of the Spirit, who writes it in our hearts).

Without this both legalist and antinomian remain wrongly related to God’s law and inadequately related to God’s grace. The marriage of duty with delight in Christ is not yet rightly celebrated.

Ralph Erskine, one of the leading Marrow Brethren, once said that the greatest antinomian was actually the legalist. His claim may also be true the other way around: the greatest legalist is the antinomian.

But turning from legalism to antinomianism is never the way to escape the husband whom we first married. For we are not divorced from the law by believing that the commandments do not have binding force, but only by being married to Jesus Christ in union with whom it is our pleasure to fulfill them. Thomas Boston himself is in agreement with this general analysis:

This Antinomian principle, that it is needless for a man, perfectly justified by faith, to endeavour to keep the law, and do good works, is a glaring evidence that legality is so engrained in man’s corrupt nature, that until a man truly come to Christ, by faith, the legal disposition will still be reigning in him; let him turn himself into what shape, or be of what principles he will in religion; though he run into Antinomianism he will carry along with him his legal spirit, which will always be a slavish and unholy spirit.

A century later, the Southern Presbyterian pastor and theologian James Henley Thornwell (1812–1862) noted the same principle:

Whatever form, however, Antinomianism may assume, it springs from legalism. None rush into the one extreme but those who have been in the other.

Here, again, is John Colquhoun, speaking of the manifestation of this in the life of the true believer:

Some degree of a legal spirit or of an inclination of heart to the way of the covenant of works still remains in believers and often prevails against them. They sometimes find it exceedingly dificult for them to resist that inclination, to rely on their own attainments and performances, for some part of their title to the favor and enjoyment of God.

If antinomianism appears to us to be a way of deliverance from our natural legalistic spirit, we need to refresh our understanding of Romans 7. In contrast to Paul, both legalists and antinomians see the law as the problem. But Paul is at pains to point out that sin, not the law is the root issue. On the contrary, the law is “good” and “righteous” and “spiritual” and “holy.” The real enemy is indwelling sin. And the remedy for sin is neither the law nor its overthrow. It is grace, as Paul had so wonderfully exhibited in Romans 5:12–21, and that grace set in the context of his exposition of union with Christ in Romans 6:1–14. To abolish the law, then, would be to execute the innocent.

For this reason it is important to notice the dynamic of Paul’s argument in Romans 7:1–6. We have been married to the law. A woman is free to marry again when her husband dies. But Paul is careful to say not that the law has died so that we can marry Christ. Rather, it is the believer who was married to the law who has died in Christ. But being raised with Christ, she is now (legally!) free to marry Christ as the husband with whom fruit for God will be brought to the birth. The entail of this second marriage is, in Paul’s language, that “the righteous requirement of the law might be fulfilled in us, who walk not according to the flesh but according to the Spirit.”

This is the sense in which the Christian’s relationship to the law is that of being an “in-law”! We are not related to the law directly as it were, or the law in isolation as bare commandments. The relationship is dependent on and the new fruit of our prior relationship to Christ. In simple terms, just as Adam received the law from the Father, from whose hand it should never have been abstracted (as it was by the Serpent and then by Eve), so the new-covenant believer never looks at the law without understanding that his relationship to it is the fruit of his union with Christ.

Bunyan saw the meaning of Romans 7. An “inclination to Adam the First” remains in all of us. The believer has died to the law, but the law does not die. The law still exists to the believer. But united to Christ the believer is now able to fulfill the law of marriage and bear fruit!

Thus grace, not law, produces what the law requires; yet at the same time it is what the law requires that grace produces. Ralph Erskine sought to put this in verse form:

Thus gospel-grace and law-commands
Both bind and loose each other’s hands;
They can’t agree on any terms,
Yet hug each other in their arms.
Those that divide them cannot be
The friends of truth and verity;
Yet those that dare confound the two
Destroy them both, and gender woe.
This paradox none can decipher,
That plow not with the gospel heifer.

So, he adds,

To run, to work, the law commands,
The gospel gives me feet and hands.
The one requires that I obey,
The other does the power convey.

Head and Heart

This is a fundamental pastoral lesson. It is not merely a matter of the head. It is a matter of the heart. Antinomianism may be couched in doctrinal and theological terms, but it both betrays and masks the heart’s distaste for absolute divine obligation, or duty. That is why the doctrinal explanation is only part of the battle. We are grappling with something much more elusive, the spirit of an individual, an instinct, a sinful temperamental bent, a subtle divorce of duty and delight. This requires diligent and loving pastoral care and especially faithful, union-with-Christ, full unfolding of the Word of God so that the gospel dissolves the stubborn legality in our spirits.

Olney Hymns, the hymnbook composed by John Newton and William Cowper, contains the latter’s hymn “Love Constraining to Obedience,” which states the situation well:

No strength of nature can suffice
To serve [the] Lord aright;
And what she has, she misapplies,
For want of clearer light.
How long beneath the law I lay
In bondage and distress!
I toil’d the precept to obey,
But toil’d without success.
Then to abstain from outward sin
Was more than I could do;
Now, if I feel its pow’r within,
I feel I hate it too.
Then all my servile works were done
A righteousness to raise;
Now, freely chosen in the Son,
I freely choose his ways.
What shall I do was then the word,
That I may worthier grow?
What shall I render to the Lord
Is my enquiry now.
To see the Law by Christ fulfil’d,
And hear his pard’ning voice;
Changes a slave into a child,
And duty into choice.

We are dealing here with a disposition whose roots go right down into the soil of the garden of Eden. Antinomianism then, like legalism, is not only a matter of having a wrong view of the law. It is a matter, ultimately, of a wrong view of grace, revealed in both law and gospel—and behind that, a wrong view of God Himself.
