In Petto’s The Great Mystery of the Covenant of Grace, he spends several pages discussing whether or not the covenant of grace is conditional or unconditional. He does so in his chapter “Of the Differences between the Old and the New Covenant; and the Excellency of the latter above the former.” which notes the following:
- 1. The new covenant presupposes obedience unto life to be performed already by Jesus Christ, and so is better than the Old (Sinai), which requires an after performance of it… Hence in opposition to that Sinai law, which ran upon those terms, do and live, under the dispensation of the new, we hear so often of Believe and be saved, and he which believeth hath everlasting life, Mark xvi. 16. John iii. 16, 36…
- The new covenant represents the Lord as dealing with his people universally in a way of promise; and so is better than the old, which represents him as treating them in a way of threatening…
- The new covenant consists of absolute promises, and therefore is better than the old Sinai covenant, which ran upon conditional promises, indeed, had works as its condition… The apostle, in the text (Heb viii. 10-13), is purposely putting a difference between these; and, seeing the old covenant was unquestionably conditional, and the new here in opposition to it, or distinction from it, is as undoubtedly absolute; must it not needs be concluded, that herein stand much of the excellence of the new above the old?…
…And whereas some argue for conditions from the nature of a covenant, against that it is asserted to be a last will or testament, which may bequeath legacies without any condition.
There is a vast difference between the way of Jesus Christ his acting in the work of his mediation before and since his incarnation, and the latter is much more glorious than the former. Before, he might plead, Father, thou hast promised me, upon my obedience, hereafter to be performed, that those souls with I have undertaken for, should enjoy such blessings: There was a mutual trust between them, and so he might plead it in point of faithfulness. But now, he hath actually performed the condition of the covenant, and may plead it in point of justice. Christ being actually exhibited as a propitiation, upon that, God is said, Rom iii. 25, 26, to declare at this time his righteousness, &c.: in opposition to the time of the old testament, he says, at this time; that is, at the time of the new testament, wherein the blood of Jesus Christ is truly shed: Now God declares his righteousness in the justifying him that believes in Jesus. It is an act of grace to those who attain the remission of sin, but an act of righteousness to Jesus Christ. He may plead, Father, I have made satisfaction to the full for the sin of these souls, now declare your righteousness in pardoning of them: it is that which I have purchased for them, I have finished the work thou gavest me to do, John xvii. 4. I have paid the full price of their redemption, now let them have what I have procured for them. Thus he appears in heaven in our nature, not as a mere intercessor, but as an advocate, 1 John ii. 1: to plead that, in law, in right we are to be discharged. And this puts a great excellence upon the new covenant, that it is in itself, and to Jesus Christ, thus absolute.
And note, if some privileges of the covenant were dispensed out properly in a conditional way (as suppose justification were afforded upon faith as a condition, or temporal mercies upon obedience), yet this would be far from proving any thing to be the condition of the promise, or of the covenant itself. Indeed even faith is a particular blessing of it, and therefore cannot be the condition of the whole covenant; for what shall be the condition of faith? And there is no such special covenant now extant, as the old was, for temporal mercies; they are indefinitely promised, and sovereign grace is the determining rule of dispensing out these to the saints when they are wanted, for time and measure, as it is most for the glory of God and their good, Mat. vi. 32, 33. Nothing performed by us, then, is conditio faederis, the condition of the covenant itself; Jesus Christ has performed all required that way.
But whether any thing be conditio faederatorum is now to be considered.
Object. Is the new covenant absolute to us, or conditional?
Are there not conditional promises therein to us, as there were in the old unto Israel? Can we expect any mercy, but upon our performing some condition it is promised to?
If condition be taken improperly, for that which is only a connex action, or, medium fruitionis, a necessary duty, way, or means, in order to the enjoyment of promised mercies. In this sense, I acknowledge, there are some promises belonging to the new covenant which are conditional; and thus are many scriptures to be taken which are urged this way. That this might not be a strife of words, I could wish men would state the question thus, Whether some evangelical duties be required of, and graces wrought by Jesus Christ in, all the persons that are actually interested in the new covenant? I should answer yes; for, in the very covenant itself, it is promised that he will write his laws on their hearts, Heb viii. 10., and that implies faith, repentance, and every gracious frame; and those that have the Lord for their God are his people. If the accusation be, that there is a want of interest in Jesus Christ, they need not plead that they have fulfilled the condition of the covenant; but, that the covenant itself, in some promise of it, (which uses to be distinct from its condition,) has its accomplishment upon them therein. And those that are altogether without those precious graces, are stranger to the covenant, Eph. ii. 12.; they cannot lay claim to the blessings of it. It is our duty earnestly to be seeking after what is promised, and one blessing may be sought as a means to another; as, the spirit as a means of faith, and faith as a means to obedience, Gal. v. 6. Believing is a great duty in connexion with, and a means of, salvation; he that believes shall be saved, Mark xvi. 16. John ii. 36. Eph ii. 8. 1 Pet. i. 5, 9. There is an order in giving forth these blessings to us, and that by divine appointment; so as the neglecting to seek them therein, is highly displeasing to God. This is our privilege that divine promises are so conjoined and twisted together, for the encouragement of souls in seeking after them, that if one be taken, many more go along with it; like many links in a chain that are closed into each other. The means and the end must not be severed.
Where there is such a connexion of duties, graces, and blessings the matters may be sometimes expressed in a conditional form, with an if, as, Rom. x. 9. If thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thy heart, thou shalt be saved, Such ifs note the verity of such propositions in their connexion; they affirm this or that to be a certain truth, as that, he which believes shall undoubtedly be saved, yet that grace is not properly the condition of salvation; for, even believing is absolutely promised, so as nothing shall intervene to hinder it, Isa. liii. 10, 11. Heb vii. 10. In that improper sense, some scriptures seem to speak of conditions, viz. they intimate a connexion between covenant blessings; some are conjoined as means and end, yet the promises are really absolute for their performance.
There is a vast difference between the way of the Lord in the dispensation of covenant blessings, and the tenor of the covenant. Or, between the new covenant itself, and the means which the Lord uses for its execution and accomplishment.
The covenant itself is an absolute grant, not only to Jesus Christ, but in him to the house of Israel and Judah, Heb. viii. Yet what the Lord has absolutely promised, and is determined and resolved upon to guarantee to them, may be conditionally propounded as a quickening means to souls seeking a participation of it. As, it was absolutely determined, yea, and declared by the Lord, that those very persons which were in the ship should be preserved, Acts xxvii. 22. There shall not be a loss of any man’s life, and verse 25. I believe God, that it shall be even as it was told me. Yet, as a means to their preservation, he speaks to them conditionally, verse 31. Except these abide in the ship, ye cannot be saved. So although the salvation of all the elect, and also the causing them to believe, is absolutely intended; yet, as a means that he may urge the duty upon souls with greater vehemence and earnestness, the Lord may speak in a conditional way, if ye believe ye shall be saved, when it is certain they shall believe.
There is no such condition of the new covenant to us, as there was in the old to Israel. For, the apostle comparing them together; and, in opposition to the old, he gives the new altogether in absolute promises, and that to Israel, Heb. viii.; and, showing that the new is not according to the old, he discovers wherein the difference lay, verse 9. Because they continued not in my covenant, and I regarded them not; saith the Lord; and, Jer. xxxi. 32. which covenant they broke, &c.
This argues that the condition of the old was such as the performance of it did give them assurance of the temporal mercies promised, and a right to them, and such as failed in, left them at uncertainties whether they should enjoy them or not; so as it was not only in itself and its own nature uncertain, but even as to the event, I regarded them not, saith the Lord.
If their performing the condition had been as absolutely promised, as the blessings of the new covenant are, then Israel would have continued in it (which they did not), and could not have forfeited what was promised thereupon, as diverse times they did, and were excluded out of Canaan upon that account. – Jurists say, a condition is a rate, manner, or law, annexed to men’s acts, staying or suspending the same, and making them uncertain, whether they shall take effect or not. And thus condition is opposed to absolute.
That there is no such condition in the new covenant to be performed by us, giving right and title to the blessings of it, and leaving at uncertainties and liability to missing of them, as there was in the old to be fulfilled by Israel, may appear,
1._ If there be any, it must either be an antecedent or a subsequent condition; but neither. There can be no such antecedent condition, by the performance of which we get and gain entrance or admittance into covenant; for, till we be in it, no act put forth by us can find any acception with God, Heb. xi. 6. Without faith, it is impossible to please God. And our being, in covenant is, in order of nature, (though not of time,) before faith; because it is a privilege or benefit of the covenant, a part of the new heart, a fruit of the spirit; and so the spirit (which is the worker of it, and another blessing of the covenant,) is given first in order before it. Jesus Christ is the first saving gift, Rom vii. 32., and with him he freely giveth all things. Men ought to be in the use of means; but it is the act of God that gives admission into the covenant, Ezek. xvi. 8. I entered into covenant with thee, saith the Lord God, and thou becamest mine. Immediately before, they were polluted in their blood, verse 6.; in an utter incapacity for acting in any pleasing way, so as to get into covenant. Neither is there any subsequent condition to be fulfilled by us: the use of that is, for the continuation of a right, and upon failing thereof, all is forfeited, as in the case of Adam. – Whereas there is no act of ours whereby our right to covenant blessings is continued unto us, upon failing whereof they may be forfeited. Our right, and the ground of our, claim, is upon a higher account than any act of our own; it is even the purchase of Jesus Christ; and they are the sure mercies of David, Isa. lv. 3. Sure to all the seed, Rom. iv. 16. And when they are become believers, eternal life is absolutely promised, John iii. 16, 36. 1 John v. 10, 11, 12., but conditionally, promised to them.
2._ The Lord has given assurance that there shall never be an utter violation of the new covenant, and therefore it has no such condition as was annexed to the old; for, the Lord declares that they had broken his covenant, Jer xi. 3, 4, 10. Jer xxxi. 32. But the new covenant is secured from such a violation: it cannot be disannulled so as the persons interested in it should be deprived of the great blessings promised therein, Jer. xxxii. 40. I will make an everlasting covenant with them. But may there not be such a condition of it as they may come short of all its blessings? No: I will not turn away from them to do them good, but I will put my fear in their hearts, that they shall not depart from me. If there were any danger of forfeiting and losing these, it must be either on God’s part, by his leaving of them, or on their part, by their departing from him; and here the Lord has undertaken to secure against both these, and so the matter is out of question; it was not thus in the old covenant.
Indeed what the Lord hath absolutely promised, yet he has appointed means in order to the attaining of it, internal as faith, and external as ordinances; and commands utmost attendance upon him ordinarily in the use thereof; this is necessary as a duty, and sin arises upon neglect of it. Thus the Lord is unalterably determined to guarantee a frame of obedience, Ezek. xxxvi. 25-30. Yet obedience is to be performed by us; we are to be the agents, and we may sin about the means in the way to the enjoyment of such mercy, as is laid up in absolute promises – Faith is to be exercised in these, (else what use are they of?) and we may be faulty in not attending to it.
3._ If there be any such condition of the new covenant, it were most like to be precious faith; but that is not…
4._ Our obedience, though evangelical, is no such condition of the new covenant, as there was of the old unto Israel.
Summary and Comparison
Petto goes on to argue several other points at length and list other differences between the new and old covenants besides their conditionality. To summarize his point, we can say that the new covenant is not like the old covenant because the old covenant could be broken, but the new cannot. Everything required of us in the new covenant is also a blessing of the new covenant. Apostasy from the new covenant is impossible.
Compare Petto’s view with standard Reformed thinking today, such as the PCA Book of Order:
By virtue of being children of believing parents they are, because of God’s covenant ordinance, made members of the Church, but this is not sufficient to make them continue members of the Church. When they have reached the age of discretion, they become subject to obligations of the covenant: faith, repentance and obedience. They then make public confession of their faith in Christ, or become covenant breakers, and subject to the discipline of the Church.
PCA Book of Order 56-4.j
Paedobaptism (or at least the reasoning of 98% of Reformed paedobaptists) is founded upon a faulty understanding of the New Covenant. It is not possible for someone to be a new covenant breaker.
This difference between Petto and the majority Reformed position is precisely why I find Mark Jones’ comments in the forward to Petto’s book so unhelpful.
The history of Reformed covenant theology has not always been well understood. Richard Greaves refers to Petto, as well as Owen, Goodwin, and Ussher, as “strict Calvinists” who belong to one of three different groups in the covenant tradition. Greaves mistakenly posits a tension between the Calvin-Perkins-Ames tradition, which supposedly distinguished itself by promulgating an unconditional character to the covenant of grace, and the Zwingli-Bullinger-Tyndale tradition, which is characterized by the conditional nature of the covenant of grace. Graves is wrong to place these two groups in tension with one another. The truth is that both ‘groups’ understood the covenant of grace as having conditions; namely, faith and obedience. However, because the faith and obedience that is required in the covenant of grace is the “gift of God” it may also be said that the covenant of grace is some sense unconditional. These nuances have often been missing in the twentieth-century historiography.
Per my reading, Jones attempts to obliterate the distinction Petto labors to carefully establish between his view and the view of those who believe one can break the new covenant by arguing there really is no difference.
