Revised Complementary Hermeneutics: A Proposal for Progressive Dispensationalism

1. The Contribution of Bock's Complementary Hermeneutics

The Complementary Hermeneutics (CH) proposed by Darrell Bock represents an important contribution within Progressive Dispensationalism. Although not all progressive dispensationalists hold to it (Vlach, for example, do not employ CH), it, in my view, corrects two extremes: on one hand, traditional dispensationalism, which tends to keep the Old and New Testaments in such separate compartments that the continuity of God's plan becomes obscured; on the other hand, replacement theology, which nullifies the promises made to Israel by transferring them entirely to the Church.

Bock's great insight was to show that the New Testament does not replace the Old — it comes alongside it. Later revelation complements prior promises. The Church does not replace Israel in God's eternal plan. This view preserves the integrity of the Old Testament promises while recognizing the genuine newness of what Christ inaugurated. It is a contribution of immense value, and this article stands on the shoulders of that work.

However, there is one point where I believe CH could be refined, and this is a proposal in that direction. What I present here is not a rejection of Complementary Hermeneutics, but rather an adjustment that, in my view, strengthens CH itself by making it more precise. It is a variation — a fine-tuning on a single point. The substance of CH remains intact. The RCH should be read as an attempt to preserve, with greater terminological discipline, Bock's own commitment to original meaning, authorial intent, and stable meaning.

2. A Question of Fine-Tuning: Where Exactly Is the Complementation?

The question that motivates this article arises from within Complementary Hermeneutics itself, when we take it seriously alongside grammatical-historical hermeneutics.

Consider these two statements by Bock. The first:

“

"New teaching develops promise by coming in alongside the old promise, except in those cases where the old promise is explicitly said to be set aside. That is the complementary nature of promise. The church does not replace Israel in God's eternal plan." (Darrell Bock, Current Messianic Activity and OT Davidic Promise)

With this statement, my agreement is total. The promise throughout revelation is progressively complemented. The content of the covenants is also complemented and progresses. New revelation comes alongside the old — not above it, not in place of it.

Now consider this other statement:

“

"Such complementary readings do not introduce instability into interpretation because meaning is never lost; it is only deepened and enhanced." (Darrell Bock, Three Central Issues)

Here the tension arises. When Bock says that meaning is "deepened and enhanced," what exactly is being deepened? The meaning of the text itself? Or the element to which the text points?

The question may seem subtle, but it has important implications — and many theologians have not noticed this crucial difference. If it is the meaning of the text that is deepened, then the meaning itself is complemented: although nothing is subtracted from the original sense, something is added to it. If, on the other hand, what is deepened and complemented is the promise as an entity distinct from the text, then the meaning of each text remains intact, and the progression occurs at the level of the promise, not of the text.

And this is precisely the point at the heart of Complementary Hermeneutics that could benefit from greater precision. In his own writings, Bock sometimes places complementation at the level of the referent — the promise, the covenant, the real entity to which the text points — and there the RCH agrees entirely. But at other times he places complementation at the level of the sense — the meaning of the text itself — speaking of meaning being "deepened," "enhanced," or "expanded." The two levels are not interchangeable. The fact that these two levels are not always explicitly distinguished in the formulation of CH is what creates the ambiguity the RCH seeks to clarify. The categories are Bock's own; the RCH simply proposes greater consistency in applying them.

The question is not whether there is complementation. There is — on this the agreement is full. The question is where it operates. And the heart of this article is to show that we must carefully distinguish the meaning of a text from the element to which it points — a promise, a covenant, a theological theme. In my view, this ambiguity — which manifests itself in the movement between sense and referent — can lead to formulations that are less precise than they need to be.

3. The Thesis: Revised Complementary Hermeneutics

The proposal I call Revised Complementary Hermeneutics (RCH) can be summarized as follows:

Stated concisely: the RCH holds that complementation operates at the level of the theological element to which the text points (promise, covenant, theme), never at the level of the grammatical-historical meaning of the individual text. The meaning of each text is fixed; what progresses is the element revealed by the collection of texts.

And this is precisely why canonical reading — reading that considers the whole of biblical revelation — is so important. It is not dispensable; it is essential. But what canonical reading does is shed light and greater understanding on the elements to which the texts point, not alter the meaning of the texts themselves. When I read Jeremiah 31 in light of Ephesians 2, my understanding of the New Covenant is enriched — but the meaning of Jeremiah 31 remains the same. Canonical reading complements my understanding of the subject in question, not the meaning of the texts that reveal it.

4. Interacting with Bock: Agreement and Proposed Refinement

One of the strengths of the RCH is that it does not stand against Bock's work — it stands within it, seeking greater precision. To make this clear, it is worth examining a number of Bock's own statements. And here the pattern this article seeks to clarify becomes visible directly in Bock's own words: when Bock places complementation at the level of the referent — the promise, the covenant, the theological entity — the RCH agrees fully. When he places it at the level of the sense — the meaning of the text — the RCH introduces its adjustment. The movement between these two levels is the precise point the RCH seeks to clarify.

Where the RCH Fully Agrees — Complementation at the Level of the Referent

The agreement between the RCH and Bock is broad and substantial. In each of the following statements, notice that Bock locates the complementation at the level of the promise, the covenant, or the theological program — that is, at the level of the referent, not of the sense of any individual text.

Bock writes:

“

"What is unique in the present articulation of the 'already/not yet' tension is a complementary hermeneutic that insists that NT fulfillment does not resignify OT meaning. In other words, both OT promise and its NT connection should be studied in their own contexts before the two Testaments are related to each other. New teaching develops promise by coming in alongside the old promise, except in those cases where the old promise is explicitly said to be set aside." (Current Messianic Activity)

The RCH says amen. NT fulfillment does not resignify OT meaning. Each Testament should be studied in its own context. New teaching comes alongside, not in place of the old. This is precisely what the RCH seeks to preserve.

Bock also affirms:

“

"An OT promise made to a specific recipient must benefit that recipient, even if the promise is later expanded to include others." (Current Messianic Activity)

Again, full agreement. Expansion does not nullify the original recipient. The older son still receives what was promised to him, even when the younger son is included.

On the New Covenant specifically, Bock states:

“

"For example, the new covenant is expanded to include Gentiles, even though it originally was given to Israel." (Current Messianic Activity)

The RCH agrees entirely. The New Covenant is expanded. But notice: what is expanded is the covenant — the theological entity — not the meaning of Jeremiah 31.

Commenting on Matthew 13:52, Bock writes:

“

"Jesus' kingdom revelation as mystery complements OT kingdom teaching. It adds to it as part of the same program... it contains both old and new elements." (Current Messianic Activity)

The RCH agrees. The "new and old" does not mean that the old changes its sense. The growth occurs in the program, in the promise, in the theme — not in the historical sense of each individual text.

Bock further states:

“

"Promise is inherently forward looking; and as such, promise lays groundwork for expansion without demanding that all elements of the promise's realization be present explicitly from the beginning. Progress and expansion can emerge as more pieces of the promise are brought together into a unified whole or as more of its elements are revealed." (Current Messianic Activity)

This statement directly supports the RCH thesis. The promise is inherently open to expansion — but it is the promise that expands, not the meaning of the texts that reveal it. Bock himself speaks of "pieces of the promise" being "brought together." The "pieces" are the individual texts, each with its fixed meaning. The promise is the "unified whole" produced by the collection of those texts.

And finally:

“

"This we have called a 'complementary hermeneutic,' as what the NT reveals complements and completes what the OT reveals without losing what was originally declared, provided that the OT expression is still affirmed either by explicit NT declaration, by an allusion back to what was said in the past, or through explicit nullification language." (Progressive Dispensationalism, in Covenantal and Dispensational Theologies)

The RCH embraces this fully. What the NT reveals complements what the OT reveals — without losing what was originally declared. Nothing is lost. The RCH simply adds: and nothing is retroactively added to the meaning of the original text either.

Where the RCH Proposes Its Refinement — Complementation at the Level of the Sense

In the following statements, notice that Bock speaks of "meaning" being deepened, expanded, or enhanced — which is to place complementation at the level of the sense, not of the referent.

Bock writes:

“

"Such complementary readings do not introduce instability into interpretation because meaning is never lost; it is only deepened and enhanced." (Three Central Issues)

The RCH does not agree with this formulation, because it places complementation at the level of the sense — the meaning of the text — rather than at the level of the referent. What is deepened and complemented is the element to which the text points — the referent — because new revelations contribute new information about it. The sense of the text remains what it always was; what grows is the referent, as later texts reveal more about the same promise, covenant, or theme.

A particularly illuminating statement is this one:

“

"Does the expansion of meaning entail a change of meaning? This is an important question for those concerned about consistency within interpretation. [...] On the one hand, to add to the revelation of a promise is to introduce 'change' to it through addition. But that is precisely how revelation progresses, as referents are added to the scope of a previously given promise. If the promise were present with its full meaning from the start, then where would the revelatory progress of promise reside?" (Current Messianic Activity)

Here too the framing "expansion of meaning" places complementation at the level of the sense; the RCH would say instead that what expands is the referent.

Similarly, Bock writes:

“

"He challenges our description of complementary meaning in making this charge. But he fails to adequately note that our argument is that subsequent revelation can add meaning — not by change (as he claims we argue) but by expansion and elaboration." (Progressive Movement, in Discovering Dispensationalism)

The RCH appreciates the intent — Bock is rightly insisting that nothing is lost or changed — but proposes a more precise formulation: subsequent revelation adds to the covenant or promise, not to the meaning of any individual text.

Finally, consider this statement:

“

"The teaching of the Old Testament is not changed or overridden; rather it is either deepened, made more specific, or is given additional elements." (Evangelicals and the Use of the OT in the New, Part 1)

Here the RCH agrees, because Bock speaks of "the teaching of the Old Testament" — not the meaning of a specific text. The teaching of the OT as a whole can indeed be deepened and given additional elements, because the teaching is the cumulative result of multiple texts. That is different from saying that the meaning of an individual text is deepened. The RCH makes this distinction explicit.

5. The Central Distinction: The Meaning of the Text and the Element to Which It Points Are Distinct Entities

The meaning of a text and the element to which that meaning points — whether a promise, a covenant, a theological theme — are two entities of a different nature. They are not the same thing seen from different angles — they are distinct things, which exist in distinct ways and behave in distinct ways. Conflating them is the source of the ambiguity the RCH seeks to resolve.

The meaning of a text is fixed. It is anchored in the intention of the original author, in the words he chose, in the historical context in which he wrote, and in the audience he addressed. It is a linguistic and historical entity. It is determined at the moment the text is produced and does not change afterward — just as the content of a letter does not change after it is sent. What Jeremiah meant when he wrote chapter 31 is what Jeremiah 31 means — yesterday, today, and always.

The element to which the text points — a promise, a covenant, a theological theme — is the real object that exists beyond the text. It is a theological and redemptive-historical entity that develops over time, through multiple revelations, each contributing its part.

The same is true of biblical texts and the theological entities to which they point. The New Covenant, for example, is not Jeremiah 31. Jeremiah 31 is one of the revelations about the New Covenant. The New Covenant is greater than any single text that speaks of it. The same is true for the Kingdom of God, for the Abrahamic promise, for the Davidic promise — each of these elements is progressively revealed by multiple texts, but no individual text is the element itself. Each text reveals a portion; the element is the sum.

Think of it like a diamond displayed in a gallery. A viewer standing to the north sees a flash of blue. Another, from the east, sees a deep red. A third, from above, sees a burst of white light. Each viewer gives a true description — but no single description is the diamond. The diamond is the referent, the real object. Each description is a text with its own fixed sense, capturing one facet of the same stone. To know the diamond fully, you need every vantage point. But the description from the north does not change when the eastern observer reports what he sees. Each remains what it was — a true account of one facet. What grows is our knowledge of the diamond, not the content of any single description. In the same way, each biblical text reveals one facet of the theological entity to which it points. 2 Samuel 7 reveals one facet of the Davidic promise — an enduring dynasty and a son who will build the temple. Psalm 2 reveals another — the Son installed as King on Zion, to whom the nations are given as inheritance. Isaiah 9 reveals yet another — a child born, a government on his shoulders, a throne of justice and peace forever. Each text has its own sense, fixed in its own context. The Davidic promise — the referent — is the full diamond, progressively revealed as God, through different authors in different centuries, turned the stone and showed another facet.

Bock himself provides a striking confirmation of this point. Speaking of the Davidic promise, he writes:

“

"The revelation of the Davidic and kingdom promise is not limited to 2 Samuel 7. This may well be the most crucial point in the entire discussion. 2 Samuel 7 is but the start of the promise about a specific dynasty. The promise includes all the OT texts that develop the Davidic hope (Psalms 2, 16, 89, 110, 118, 132; Isaiah 9–11, 55; Jeremiah 23, 30, 33; Ezekiel 34–37; Daniel 2, 7, 9; Hosea 3; Amos 9; Zechariah 12–14), plus any NT texts linked to messianic hope." (Current Messianic Activity)

This is precisely what the RCH argues, and it can be stated in terms of the distinction at the heart of this article. 2 Samuel 7 has a meaning — its linguistic content: God's promise to David of an enduring dynasty, a son who will build the temple, a throne established forever. That is the sense of the text — what it communicates. And this sense points to a referent — the Davidic promise, a real theological entity in God's redemptive plan. But as Bock himself shows, the Davidic promise is far greater than what 2 Samuel 7 alone says about it. It is a theological entity that spans dozens of texts across centuries of revelation. The sense of 2 Samuel 7 is fixed — it reveals the portion of the Davidic promise known at that moment. The Davidic promise in its fullness is progressively revealed by many texts, each contributing its portion. And if this is the case, then complementation occurs at the level of the referent — the promise, which grows as new texts add to it — not at the level of the sense of 2 Samuel 7, which remains what it always was.

This distinction is obvious in every other field

A doctor examines a patient and writes a report: "The patient presents a 2cm lesion in the right lung." Months later, new tests reveal that the lesion has grown to 5cm and has spread. The original report was not "deepened" — it still says exactly what it said: 2cm lesion, right lung. What progressed was the disease, the real object to which the report referred. To say that the meaning of the report was "complemented" by the findings of the new tests would be like going back to the original report and changing "2cm" to "5cm" — as if the first examination were wrong or incomplete for not describing what had not yet happened. No doctor would do this. The first report was accurate at the time it was written. The subsequent tests revealed more about the same disease, but each report retains its own meaning.

What happens when the two are conflated

Conflating the meaning of a text with the element to which it points is like saying that Jeremiah 31 "always included the Gentiles" because the New Covenant, in its full development, came to include them — when Jeremiah explicitly wrote "the house of Israel and the house of Judah." The error is the same as rewriting the medical report to fit the latest test results: projecting onto the text something that belongs to the element to which it refers. Jeremiah 31 is not the New Covenant — it is a revelation about the New Covenant. When revelation advances, the element is expanded. But the old text that spoke about it does not change retroactively. It described the portion known at that moment — and it continues to describe exactly that portion.

The text is like a map, and the element to which it points is the territory. When an explorer discovers new regions and draws a new map, the old map is not "deepened" — it continues to represent what it represented. What grew was the known territory. Confusing the map with the territory is a category mistake. And it is precisely this conflation that the RCH seeks to avoid.

Bock's own categories: sense and referent

The ambiguity identified above is not merely inferred — Bock himself provides the very categories that bring it to light. In Evangelicals and the Use of the Old Testament in the New (Part 2, Bibliotheca Sacra), he draws a distinction between sense and referent:

“

"Meaning involves the sense of a passage and not primarily the referents of a passage; but the language of an Old Testament passage and its New Testament fulfillment can be related in terms of referents in one of several ways."

And shortly after:

“

"Though a variety of relationships exist at the level of the referent, the basic sense of the passage is maintained."

In an earlier article (Part 1), Bock cites E. Johnson to define these terms more precisely:

“

"'Sense' refers to the verbal meaning of language expressed in the text regardless of the reference, that is, 'sense' involves the definition of a term, not what the term refers to. 'Reference' indicates what specifically is referred to through the sense meaning. There is a difference between what is described and meant (sense) and to whom or what it refers (reference)."

These statements deserve careful attention, because they contain, in seed form, exactly what the RCH proposes.

The sense of a text is its linguistic content — what the words communicate in their grammatical-historical context. The referent is the real object to which the text points — the entity in God's plan that the text is talking about. When Jeremiah 31 says "I will make a new covenant with the house of Israel and with the house of Judah," the sense is the linguistic content of that statement — a new covenant, with Israel and Judah, different from the former one. The referent is the New Covenant itself — the real entity in God's redemptive plan to which the text points.

Now notice what Bock is saying. First: meaning involves primarily the sense, not always the referent. Second: at the level of the referent, there is variety and development, but the basic sense of the passage is maintained. In other words, Bock himself acknowledges that the sense of a text is fixed, while the referent may be the subject of further revelation and development.

This is precisely the distinction the RCH is built upon. The sense of Jeremiah 31 is fixed. The referent — the New Covenant — is progressively revealed across multiple texts, each contributing its portion. New texts (such as Ephesians 2–3) point to the same referent and reveal more about it, but they do not alter the sense of Jeremiah 31. The referent is the same; the sense of each text is different and stable.

The tension arises when Bock, in another context, says that meaning is "deepened and enhanced." If meaning is primarily the sense, and the sense is maintained, how can the meaning be deepened? What is deepened is not the sense of any individual text — it is our knowledge of the referent, the element to which the text points. When later revelation shows that the New Covenant includes the Gentiles, the referent (the New Covenant) is shown to be larger than what Jeremiah 31 alone revealed. But the sense of Jeremiah 31 remains unchanged.

In other words, Bock's own distinction between sense and referent, if applied with full consistency, leads to the RCH. The RCH does not introduce foreign categories — it takes the categories Bock himself provides and draws out their natural consequences. If meaning is primarily about the sense, and the sense is maintained, then complementation cannot operate at the level of meaning. It operates at the level of the referent — the element to which the text points.

It is worth noting that this same distinction has deep roots in the philosophy of language. In 1892, the philosopher Gottlob Frege drew a now-classic line between Sinn (sense) and Bedeutung (reference). The sense of an expression is the way it presents its object — it is fixed and linguistic. The reference is the real object to which the expression points — and that object may have properties that the sense does not capture. Frege's Sinn corresponds to Bock's sense, and Frege's Bedeutung corresponds to Bock's referent. The convergence is remarkable: the philosophy of language and biblical hermeneutics, independently, arrived at the same fundamental distinction. The RCH simply insists that this distinction be honored in practice — that what is complemented is the referent, never the sense.

6. Illustration 1 — The Cumulative Letters

To make this distinction even more concrete, consider the following scenario.

A father writes three letters to his son, in different months:

Letter 1: "I will give you $10 at the end of the year because you were good this month."

Letter 2: "I will give you an additional $10 at the end of the year because you were good this other month."

Letter 3: "I will give you an additional $10 at the end of the year because you were good this month as well."

Here we have, on a simple scale, the same structure we find in biblical revelation: multiple texts, written at different times, pointing to the same element — in this case, a promise from the father to the son.

Each letter has its own meaning, fixed at the moment it was written. Letter 1 means $10, for a specific reason. Letter 2 means an additional $10, for another reason. Letter 3, another $10, for yet another reason. When the third letter is written, the meaning of the first is not complemented or altered in any way — it continues to mean exactly what it meant when it was originally written.

What is complemented is the promise itself — the referent to which all three letters point. After Letter 1, the promise is $10. After Letter 2, $20. After Letter 3, $30. The referent grew with each new letter, but the sense of each letter remained fixed. The $30 is not the sense of any single letter — it is the cumulative content of the referent that the three letters, together, built. If every letter "already meant" $30 from the start, why did the father need to write three? The distinctions between them — the different reasons, the different months — would collapse, and the cumulative character of the promise would be erased.

7. Illustration 2 — The Generous Father (Giving more than promised is not altering the promise)

Consider a second situation. A father writes a letter to his older son:

Letter: "If you pass the school year, I will give you $5 as a gift."

The son passes. But the father, moved by generosity and for reasons he had in mind from the beginning, decides to give $10. Moreover, he decides to extend the gift also to his younger son, who was not even mentioned in the letter.

Two questions. Did the meaning of the letter change? No. The letter meant, means, and will always mean $5, to the older son, conditional on passing the school year. The father did not "deepen" the meaning of the letter by giving more and including another son. What he did was, as sovereign over the promise, go beyond what that specific letter communicated.

And did the older son lose anything? Also no. The $5 promised in the letter are contained within the $10. And the inclusion of the younger son took nothing away from the older one. The father did not give to the younger son instead of giving to the older. He gave beyond. The original promise was fully fulfilled; what the father did was go beyond it, not against it.

The theological parallel is direct. When God includes the Gentiles in the covenants of promise, Jeremiah 31 remains a promise to the house of Israel and the house of Judah — fully guaranteed. What God did was, as the sovereign Author of the redemptive plan, extend the benefits of the covenant also to the Gentiles. The inclusion of the Gentiles does not replace Israel, does not nullify the original promise, and does not rewrite any text. It comes beyond — alongside, as Bock so aptly described.

The greatness lies in the Promiser, who did more than any individual text communicated. Not in the rewriting of what was promised, and certainly not in the exclusion of those to whom the promise was originally directed.

8. Case Study: Jeremiah 31 and the Inclusion of the Gentiles

To show how the RCH works in exegetical practice, consider the case of Jeremiah 31 — perhaps the most central text on the New Covenant in the Old Testament.

The original meaning of Jeremiah 31 is clear and specific: it is a promise made to the house of Israel and the house of Judah. God will make with them a new covenant, different from the one He made when He brought them out of Egypt. He will put His law within them, write it on their hearts, be their God, and they shall be His people. That is the meaning of the text. There are no Gentiles on the horizon of Jeremiah 31.

What the New Testament reveals is that the Gentiles, who were "far off" and were "strangers to the covenants of promise" (Ephesians 2:12), were brought near and included. Paul calls this a mystery — something "which in other ages was not made known to the sons of men" (Ephesians 3:5) — namely, "that the Gentiles are fellow heirs, members of the same body, and partakers of the promise in Christ Jesus" (Ephesians 3:6).

How do we understand this? CH, as currently formulated, would say that the NT revelation "deepens" or "complements" the meaning of the text of Jeremiah 31, which now includes the Gentiles — that is, it places complementation at the level of the sense. The RCH says something slightly different: the NT did not update or complement the sense of Jeremiah 31, as if it secretly already included the Gentiles or as if it needed to be "expanded" to accommodate them. What the NT did was complement the content of the New Covenant — the real theological entity to which Jeremiah 31 pointed, but which did not depend exclusively on Jeremiah 31. In other words, the RCH places complementation at the level of the referent.

And here is a crucial detail: the basis for the inclusion of the Gentiles was not implicit in Jeremiah 31; it was in Genesis 12:3, where God promises Abraham that in him all the families of the earth would be blessed. The inclusion of the Gentiles in the New Covenant is not an "expansion" of the meaning of Jeremiah 31 — it is the fulfillment of another promise, independent, running in parallel. And it is also the content of the clear revelation of Ephesians 2–3 and Romans 11. Paul makes clear in Ephesians that the Gentiles are now co-heirs and co-partakers of the covenants of promise. In Romans 11, he uses the image of the olive tree: the Gentiles were grafted into the tree whose root is the Abrahamic covenants, and it is this root that carries the sap — the blessings of the covenants — to the grafted branches.

Jeremiah 31 continues to mean what it always meant: a promise to the house of Israel and Judah. The New Covenant is greater than Jeremiah 31 — it is a theological entity that develops throughout revelation, not the meaning of a single text. And the NT is clear in affirming that the Gentiles, who were once far off, have now been brought near in Christ and participate in this covenant. Paul revealed a new aspect of the promise that comes alongside — exactly as Bock so aptly described. Only, this "alongside" operates at the level of the covenant, not at the level of the meaning of the text.

When a traditional dispensationalist attempts to deny any relationship between the Gentiles and the New Covenant, he typically cites Jeremiah 31: the covenant is with the house of Israel and Judah. And regarding the meaning of the text, he is correct — Jeremiah 31 indeed says this and continues to say this. But the participation of the Gentiles in the New Covenant does not need to be based on Jeremiah 31. It is based on the NT revelation that in Christ we are co-partakers and co-heirs of the covenants of promise. The New Covenant is not Jeremiah 31. Jeremiah 31 is a revelation about the New Covenant. And the New Covenant, as a theological entity, today includes both Israel and the Gentiles — not because Jeremiah 31 was rewritten, but because God revealed more about His covenant than any individual text contained.

9. Objections and Responses

Any thesis that proposes a distinction invites the question of whether that distinction is real or artificial. The RCH is no exception. Two objections deserve attention.

Objection 1: "The distinction between the meaning of a text and the element to which it points is artificial. Meaning always includes the referent."

This objection conflates two levels. It is true that a text always points to something — a referent. But the meaning of a text is determined by its linguistic content in its historical context, not by the full reality of the referent. Jeremiah 31 points to the New Covenant, but the meaning of Jeremiah 31 is not the New Covenant in its totality. Jeremiah 31 reveals a portion of the New Covenant — the portion known at that moment in redemptive history. The New Covenant, as a theological entity, is larger than any single text that reveals it.

Objection 2: "This distinction undermines the unity of Scripture by treating each text as isolated."

On the contrary. The RCH does not isolate texts — it honors both the individual text and the canonical whole. Each text has its own meaning, anchored in its own context. But canonical reading brings these texts together, and the result is a richer understanding of the promise, the covenant, the theme. The unity of Scripture is not produced by making each text mean more than it originally said — it is produced by the Divine Author who, across centuries, through independent authors, built a cumulative revelation that is greater than any individual part. The RCH preserves the unity of the canon precisely by locating it where it belongs: not in the retroactive alteration of individual meanings, but in the coherent design of the whole.

10. Conclusion

The Revised Complementary Hermeneutics proposes a fine-tuning, but one with significant implications. By locating complementation at the level of the referent — the promise, the covenant, the theological entity — and never at the level of the sense — the grammatical-historical meaning of the individual text — the RCH achieves two things simultaneously.

First, it preserves the integrity of grammatical-historical hermeneutics. The meaning of each biblical text is determined by the author's intention, by his words, and by his context — and is not retroactively altered by later revelations. This closes the door to readings that, however well-intentioned, end up functioning as a subtle rewriting of the Old Testament.

Second, it maintains the beauty of progressive biblical theology. The promise grows. The covenants develop. The redemptive plan advances. There is no loss whatsoever in the grandeur of the divine design — on the contrary. The grandeur lies precisely in the fact that God, over centuries, through different authors, in different contexts, with independent texts, was building a cumulative Promise that is greater than any individual text.

Bock's Complementary Hermeneutics opened the way. The Revised Complementary Hermeneutics merely suggests that we walk along it with one additional care: that the complementation — so real and so necessary — be located where it actually operates. Not in the meaning of the texts, but in the element to which they point.
