Commentary Compass

Introduction: The Need for Both Exegesis and Theology

Biblical and systematic theology perform indispensable but distinguishable tasks. Biblical theology traces the development and interrelationships of biblical teaching within the unfolding history and literature of Scripture. Systematic theology seeks to articulate that teaching coherently, bringing together what the biblical writings say about God, creation, humanity, Christ, salvation, the church, and the last things. Neither can dispense with the other. Exegesis without synthesis risks fragmentation, while synthesis insufficiently accountable to exegesis risks constructing a theological framework more persuasive in its internal logic than in its biblical foundations.

An extensive engagement with biblical commentaries provides a particularly useful way to evaluate theological works. Commentators must confront the wording, grammar, literary structure, historical setting, and argumentative movement of individual passages. Their findings sometimes confirm established theological formulations, sometimes enrich them, and sometimes expose the weakness of interpretations that appear convincing only when detached from their contexts. Commentaries are themselves fallible: speculative historical reconstructions, elaborate literary theories, and theological preferences can distort their conclusions. Nevertheless, the best commentaries offer a form of critical discipline that even the greatest theological systems require.

This essay draws together comparisons involving John Calvin, Herman Bavinck, Geerhardus Vos, Herman Ridderbos, George Eldon Ladd, John Goldingay, Karl Barth, Wolfhart Pannenberg, Jürgen Moltmann, Brent Strawn, and David Höhne, alongside the Contours of Christian Theology series and numerous commentaries from Genesis to Revelation. The objective is not to decide whether theological creativity is legitimate. It is to distinguish theological conclusions demonstrated by Scripture, reasonable inferences from Scripture, and constructions whose elegance or attractiveness exceeds their exegetical support.

1. Scripture, Revelation, and the Foundations of Theology

Karl Barth’s Church Dogmatics, particularly I/1 and I/2, illustrates both the achievement and the danger of ambitious theological construction. Barth’s insistence that Christian theology begins with God’s self-revelation rather than autonomous human speculation is a major contribution. His account of the Word of God, the Trinity, divine freedom, and revelation in Jesus Christ offers a remarkably integrated theological vision. I/1 is particularly powerful in demonstrating that Christian doctrine cannot be reduced to religious experience, ethical philosophy, or historical reconstruction.

Yet the resulting account of Scripture raises serious questions. Barth distinguishes God’s revelation in Christ, its prophetic and apostolic witness in Scripture, and its proclamation by the church. He does not simply teach that reading the Bible turns an otherwise ordinary book into God’s Word. His argument is more sophisticated: Scripture truly serves as God’s Word through God’s free and effective act of revelation. Nevertheless, the relationship between Scripture’s abiding identity and authority and its renewed actualisation as divine speech remains problematic.

Commentary work on 2 Timothy 3:14–17, 2 Peter 1:19–21, John 10:35, and the apostolic witness points towards an important distinction between inspiration and illumination. The sacred writings are described as God-breathed, while the Spirit enables readers to receive, understand, and respond to their message. Philip Towner’s and other leading commentators’ treatment of the Pastoral Epistles, together with Ridderbos’s account of apostolic authority and the New Testament canon, supplies a firmer exegetical basis for maintaining that Scripture possesses an authoritative status not dependent on a fresh event of reception. The Spirit’s work in readers is essential, but it does not create the inspiration of the writings they read.

Barth’s willingness to recognise the biblical authors’ capacity for error, including possible limitations in their religious and theological judgments, is similarly insufficiently established from the passages he discusses. Recognising the human characteristics of Scripture—its different genres, historical settings, idioms, individual authors, and literary conventions—does not itself demonstrate theological error. Nor do differences between Paul and James, or between John and the Synoptics, necessarily constitute contradictions. Such questions require individual exegetical investigation before they can sustain general doctrinal conclusions. Barth’s comparatively open treatment of canonical boundaries also appears less secure than Ridderbos’s account of the distinctive, historically foundational authority of Christ’s commissioned apostolic witnesses.

Calvin’s Institutes, Vos’s Biblical Theology and Reformed Dogmatics, and Ridderbos’s Paul: An Outline of His Theology offer instructive alternatives. Their theological formulations are not free from inference or organising assumptions, but they generally proceed with closer attention to particular biblical arguments and the progressive development of revelation. Calvin is especially valuable for repeatedly returning doctrinal discussion to the passages on which it depends. Vos contributes a disciplined understanding of revelation through historical acts and their divinely given interpretation, while Ridderbos combines theological synthesis with careful attention to Paul’s salvation-historical reasoning. Compared with Barth, these approaches more consistently allow the biblical material to establish the scope and limits of the theological framework.

A related problem concerns Barth’s strong resistance to natural theology. His concern to protect the uniqueness of revelation in Christ is understandable, yet Psalm 19, Romans 1:18–23, and Acts 14:15–17 and 17:22–31 affirm genuine divine disclosure through creation and providence. Cranfield, Moo, Dunn, Fitzmyer, and Schreiner differ over aspects of Romans, but Paul’s argument cannot readily be reduced to knowledge available only through the special revelation of Christ. The knowledge described is neither adequate for salvation nor properly received by sinful humanity; nevertheless, its reality is integral to Paul’s argument about human accountability. Calvin, Bavinck, and Vos preserve this distinction more satisfactorily without making natural knowledge an independent route to redemption.

2. The Old Testament Must Be Heard Before It Is Systematised

The Old Testament provides a decisive test of whether a theology respects Scripture’s diversity and historical development. Its narratives, laws, poetry, wisdom, and prophetic writings cannot be reduced to interchangeable illustrations of doctrines established elsewhere. Christian interpretation rightly reads these writings within the completed canon, but their witness must first be understood within their own literary and covenantal contexts.

Genesis provides a useful example. Commentators such as Gordon Wenham, Bruce Waltke, Robert Alter, John Goldingay, and Walter Brueggemann illuminate different dimensions of creation, human identity, sin, and divine promise. Strawn’s The Incomparable God makes a worthwhile contribution by exploring the varied ways in which human beings image God within Genesis. Yet the diversity of narrative expressions does not eliminate the distinctive theological claims of Genesis 1:26–28 concerning humanity’s created status, vocation, and relationship to God. A theological synthesis must account for both the foundational creation statement and its subsequent narrative development, rather than allowing either a single abstract definition or an indefinite plurality of images to exhaust the subject.

Leviticus presents an equally important corrective. Jacob Milgrom, Jay Sklar, Roy Gane, Gordon Wenham, and other specialists demonstrate the complexity of sacrifice, ritual purification, holiness, priesthood, and atonement. The Day of Atonement in Leviticus 16 is not adequately explained by attaching a general theological label such as reconciliation or cleansing. Its particular rites, movements, objects, and distinctions must first be understood. Biblical theology can then trace their development through Hebrews 9–10, where Christ’s definitive priestly work is understood against this detailed cultic background. Typology becomes more persuasive when it arises from the actual characteristics of the earlier institutions rather than replacing them with theological symbolism.

The prophetic books require similar care. Childs, Goldingay, Seitz, and other Isaiah commentators preserve the significance of Israel’s exile, restoration, divine kingship, and the varied presentations of the servant in Isaiah 40–55. Jeremiah’s promises of covenant renewal must likewise be read against judgment, exile, restoration, and the continuing identity of Israel. The commentaries on Hosea, Amos, Zechariah, and Malachi further demonstrate that covenant faithfulness includes worship, justice, communal responsibility, and concrete obedience, not merely an abstract redemptive principle.

These observations qualify several major theological approaches. Barth’s pervasive Christological orientation offers profound insights but can allow the eventual Christological fulfilment to determine an Old Testament passage before its immediate meaning has been adequately established. Moltmann’s promise-oriented theology illuminates the future-directed character of Israel’s faith but can subordinate creation, covenantal presence, Torah, and existing divine blessings to the expectation of what is still to come. Conversely, Goldingay and Strawn rightly insist that the Old Testament has a substantial theological witness in its own right, although Christian canonical interpretation must also explain how that witness relates to the New Testament’s presentation of Christ.

Vos provides a particularly helpful balance. His redemptive-historical approach recognises both the progressive character of revelation and the integrity of its earlier stages. It gives Christian readers a principled way to connect the Testaments without presuming that every passage directly or exclusively concerns Christ. The resulting synthesis is more convincing when historical development, literary context, and canonical fulfilment illuminate rather than displace one another.

3. God’s Character, Divine Violence, and the Limits of Theological Explanation

Brent Strawn’s The Incomparable God offers a valuable reminder that Scripture’s presentation of God cannot be compressed into a narrow collection of attributes or familiar doctrinal formulas. Its attention to metaphor, literary complexity, divine incomparability, and troubling passages makes it an important contribution to biblical theology. Nevertheless, some of Strawn’s most imaginative interpretations demonstrate why detailed commentary comparison remains essential.

Exodus 34:6–7 combines divine compassion, grace, patience, covenant faithfulness, forgiveness, and judgment. Strawn perceptively resists treating this confession as a static definition that removes the complexity of God’s dealings with Israel. Yet its parallel expressions, numerical contrasts, and covenantal context also give the passage a discernible structure. God’s abundant faithfulness towards thousands stands alongside judgment extending to the third and fourth generations. Childs, Propp, Fretheim, and other Exodus commentators help clarify why the passage should not be reduced either to competing divine personalities or to an uncomplicated doctrine of mercy. The theological challenge is to explain the relationship between mercy and justice while respecting the text’s own emphases.

Psalm 137:8–9 illustrates the distinction between persuasive insight and speculative reconstruction. Strawn’s reading sensitively highlights the trauma behind the psalm’s terrible concluding wish and the poetic relationship between Babylon’s violence and the recompense envisioned against it. His suggestion that the speaker may be a bereaved parent recalling a particular rock on which a child was killed is emotionally powerful. Yet neither the definite article in the Hebrew expression translated “the rock” nor the principle of retaliatory correspondence establishes that specific historical circumstance. Berlin, Goldingay, Hossfeld–Zenger, and other Psalms commentators provide broader literary, historical, and theological controls. The psalm gives voice to devastation and a longing for justice without requiring the interpreter to reconstruct an otherwise unidentified personal tragedy.

The account of Elisha and the bears in 2 Kings 2:23–25 presents a related challenge. The narrative concerns an insult to prophetic authority within the larger Elijah–Elisha succession, but the precise age and circumstances of the offenders remain disputed. The text reports that forty-two were mauled; it does not explicitly describe the death of every individual. Provan, Cogan and Tadmor, and other Kings commentators help situate the episode within its narrative and covenantal setting. Neither an attempt to eliminate its moral difficulty nor an elaborate reconstruction designed to justify every detail provides an adequate substitute for exegesis. Strawn’s willingness to confront the passage’s disturbing character is commendable, but a theological explanation must distinguish what the narrative states from what interpreters infer.

Rachelle Gilmour’s Divine Violence in the Book of Samuel offers a further example of the value and limitations of critical theological interpretation. Her attention to the ambiguities of Saul’s kingship, divine regret, David’s wrongdoing, and apparently disproportionate violence prevents premature harmonisation. Brueggemann and Auld support important aspects of her political and literary readings. Yet close comparisons with Tsumura, McCarter, Gordon, Arnold, and others reveal weaknesses when Saul’s conduct in 1 Samuel 15 is explained principally through misunderstanding, or when the narrative’s clear attribution of Uriah’s death to David in 2 Samuel 12 is insufficiently acknowledged. Similarly, the Gibeonite executions in 2 Samuel 21 should not be treated as though the narrative unambiguously records a direct divine prescription of every action undertaken.

The broader lesson extends beyond these particular authors. Theology must resist both the impulse to explain away difficult biblical evidence and the temptation to turn literary ambiguity into a preferred theological conclusion. The commentators on Job, Judges, Samuel, Kings, and the Psalms repeatedly show that the biblical writers can preserve unresolved tensions, moral complexity, human protest, and divine judgment without necessarily providing the explanations a later systematic theologian would prefer.

4. Christology, Trinity, and the Direction of Theological Reasoning

Barth and Pannenberg represent two of the most intellectually substantial modern approaches to Christian doctrine, but their methods differ significantly. Barth begins from the self-revelation of the triune God in Jesus Christ, while Pannenberg seeks to demonstrate the universal significance of Christian truth through history, reason, and the anticipatory revelation of the future in Christ’s resurrection. Both approaches possess substantial theological strengths, and both require careful testing against the biblical sources.

The Johannine commentaries of Michaels, Brown, Barrett, Ridderbos, Klink, and others demonstrate how the relationship between the Father and Son emerges from the narrative and discourse of the Fourth Gospel. John 1:1–18, 5:19–30, 14–17, and 20:28 provide a rich textual foundation for Christology and Trinitarian reflection. The doctrine of the Trinity is not presented as a fully developed technical formulation in any single passage; it is a theological synthesis required to account for the cumulative biblical witness. This makes conceptual development legitimate, but it also means that proposed Trinitarian formulations must remain accountable to the actual distinctions and relationships expressed in Scripture.

Barth’s Trinitarian treatment in Church Dogmatics I/1 is an extraordinary achievement in theological integration. Nevertheless, his terminology of divine “modes of being” and his particular account of Trinitarian relations require justification beyond the elegance of the resulting system. Calvin, Bavinck, Gerald Bray, and Robert Letham provide useful comparators, while the Johannine evidence remains indispensable. A theological formulation does not become authoritative simply because it successfully connects several established doctrines.

Pannenberg’s Systematic Theology, across its three volumes, is particularly impressive in bringing historical theology, philosophical reasoning, Christology, creation, and eschatology into conversation. His insistence that Christian claims concern public reality rather than merely private religious experience is valuable. His emphasis on the resurrection as the decisive anticipation of the future also has substantial biblical foundations. Yet the system’s historical and philosophical coherence can occasionally exert pressure on particular passages. The proposed Adamic background to Philippians 2:5–11, for example, is less secure than an argument principally grounded in the hymn’s language of Christ’s status, humiliation, obedience, and exaltation. Fee and other Pauline commentators demonstrate why possible Old Testament echoes should be weighed rather than assumed.

This is where Calvin, Vos, and Ridderbos remain especially instructive. They do not avoid doctrinal synthesis, but their strongest arguments generally move from particular passages towards theological conclusions instead of using a comprehensive conceptual scheme to settle disputed exegesis. Their example suggests that Christological centrality is most convincing when established through the distinctive witnesses of the Gospels, Paul, Hebrews, and the other biblical writings, not when asserted as a principle that predetermines what those witnesses must say.

5. Covenant, Israel, and the Church

A further test of theological synthesis concerns the continuing significance of Israel and the relationship between the Old and New Testaments. Romans 9–11 is especially important because Paul addresses Israel’s election, unbelief, divine judgment, mercy, and future while explicitly rejecting the conclusion that God’s word has failed. Cranfield, Dunn, Moo, Fitzmyer, and other commentators disagree about individual and corporate election and the precise identity of “all Israel” in Romans 11:26. Nevertheless, Paul’s sustained engagement with Israel’s history and promises resists any simple account in which the church replaces Israel without remainder.

The same concern arises in interpretations of Isaiah, Jeremiah, and 1 Peter. The language of a holy priesthood and chosen people in 1 Peter 2:5–10 appropriates Israel’s covenantal vocabulary for the Christian community, but its significance must be established from Peter’s argument and the Old Testament passages he invokes. Commentators such as Achtemeier, Jobes, Goppelt, and Feldmeier provide important resources for distinguishing genuine canonical development from a theological system’s tendency to erase historical and textual particularity.

Strawn’s resistance to treating the Old Testament as valuable only because of its subsequent Christian interpretation is therefore a useful corrective. Barth’s Christological concentration and some forms of comprehensive redemptive-historical theology can weaken their explanations when Israel’s own covenantal witness becomes merely preparatory. Conversely, a reading that isolates Israel’s Scriptures from their Christian canonical reception does not adequately address the New Testament’s claims about Christ. The more persuasive approach maintains both historical integrity and canonical relationship, allowing neither to cancel the other.

6. Resurrection, Judgment, and the Christian Hope

Eschatology provides perhaps the clearest illustration of theological imagination both illuminating and exceeding biblical evidence. Moltmann’s Theology of Hope powerfully restores the future resurrection and God’s promised transformation of creation to the centre of Christian expectation. Its engagement with biblical promise and resurrection offers a necessary correction to the reduction of Christian hope to inward religious experience or the immortality of an immaterial soul. Romans 8:18–25 and 1 Corinthians 15 provide substantial support for its emphasis on bodily and cosmic renewal.

Yet the commentaries also reveal the limits of making futurity the dominant organising principle. Paul’s theology includes present participation in Christ, the indwelling Spirit, accomplished reconciliation, and the existing blessings of salvation alongside their future consummation. Fee, Moo, Dunn, and other Pauline interpreters illuminate this already-and-not-yet structure. Similarly, the Old Testament includes divine presence, creation’s goodness, covenant fellowship, and present acts of deliverance as well as promises of future restoration. A theology of hope must preserve both dimensions rather than allowing the future to determine the significance of everything that precedes it.

Moltmann’s later The Coming of God offers a richer account of bodily resurrection, new creation, divine indwelling, the vindication of victims, and the defeat of evil. Its refusal to treat Christian eschatology as escape from creation is particularly compelling. Revelation 21–22, read alongside Isaiah’s new-creation prophecies and Romans 8, strongly supports a hope involving the renewal of God’s creation and the dwelling of God with his people. Beale, Koester, and other Revelation commentators bring greater precision to the relationship between the book’s imagery, Old Testament allusions, and its final vision.

The major difficulty arises when Moltmann advances universal salvation, postmortem evangelisation, and a predominantly restorative understanding of final judgment. First Peter 3:19 and 4:6 do not unambiguously describe an opportunity for repentance after death. Achtemeier, Jobes, Goppelt, and other commentators demonstrate the substantial interpretive difficulties surrounding the spirits in prison, the proclamation associated with Noah’s generation, and the gospel preached to those described as dead. These passages are too disputed to bear the theological weight Moltmann assigns them.

Matthew 25:31–46 and Revelation 20:11–15 present additional obstacles. Although interpreters disagree about the identity of the “least of these” in Matthew 25 and the precise arrangement of events in Revelation 20, the judgment scenes cannot readily be reduced to a temporary remedial process. The parallel outcomes in Matthew 25:46 and the judgment imagery in Revelation must be taken seriously. Koester and Beale also show that the millennium in Revelation 20 remains exegetically disputed; a particular chronological construction cannot simply be made essential to the structure of Christian hope. Moltmann’s hope for comprehensive reconciliation is understandable as a theological aspiration, but it is not adequately established as the necessary conclusion of these passages.

Pannenberg’s third volume offers a different but related challenge. His account of judgment as the disclosure of human lives before divine eternity is intellectually illuminating, and his understanding of salvation preserves an important relationship between Christ, history, and the final consummation. Nevertheless, his extension of 1 Corinthians 3:10–15 towards a general doctrine of purifying judgment exceeds the passage’s immediate concern with the work of those building upon the church’s foundation. Fee and Thiselton clarify this argumentative setting. Pannenberg carefully distinguishes his conception of purifying judgment from the medieval doctrine of purgatory, but that distinction does not by itself establish his broader application of Paul’s imagery.

David Höhne’s The Last Things, the concluding volume of the Contours of Christian Theology series, offers a more explicitly evangelical eschatological synthesis, drawing constructively but critically on Barth and Moltmann. Its strengths include the resurrection of the body, the Christian life under the promise of Christ’s return, and the relationship between present discipleship and future consummation. Höhne also resists the universalist implications of Moltmann’s theology. Nevertheless, the extensive discussion of life in the present age sometimes comes at the expense of sustained engagement with the particular questions traditionally associated with eschatology.

His treatment of the Lord’s Prayer illustrates both the attraction and the limitation of this method. Höhne acknowledges the ordinary request for daily sustenance in Matthew 6:11 but develops it extensively in relation to future preservation and resurrection. This perspective can enrich theological reflection, yet Matthew’s immediate context and the parallel petition in Luke 11:3 should retain priority. His criticism of Calvin’s treatment of bodily provision is also less persuasive than it initially appears, since Calvin explicitly recognises the legitimacy of praying for ordinary physical needs. Similarly, discussions of the intermediate state must reckon with Luke 23:43, Philippians 1:23, 2 Corinthians 5:6–8, and Revelation 6:9–11, even when questions concerning the precise condition of departed believers remain unsettled.

Taken together, Moltmann, Pannenberg, and Höhne make substantial contributions to Christian eschatology. Each corrects genuine limitations of narrower theological approaches. Yet their comparison with the commentaries illustrates a recurring principle: a theological account of hope becomes less reliable when the promise of a satisfying resolution governs the interpretation of passages that do not themselves establish that resolution.

7. What the Best Theological Works Have in Common

The preceding comparisons do not support a simple division between trustworthy traditional theologians and untrustworthy modern innovators. Calvin, Vos, Ridderbos, Bavinck, Barth, Pannenberg, Moltmann, Strawn, and Höhne work with different methods and objectives. Each makes contributions that would be impoverished by dismissing the others. Moreover, historical-critical scholarship often uncovers linguistic, historical, and literary evidence that traditional interpreters have overlooked, while confessional theology can preserve canonical relationships and doctrinal implications neglected by narrowly historical approaches.

The Contours of Christian Theology volumes offer a useful illustration of constructive doctrinal synthesis. Bray on God, Ferguson on the Holy Spirit, Macleod on Christ, Letham on Christ’s work, Clowney on the church, Helm on providence, Jensen on revelation, and Sherlock on humanity provide complementary treatments of doctrines that no single biblical passage exhausts. Their differing engagements with Barth also demonstrate that appreciating his contributions does not require accepting his whole theological framework. Höhne’s volume illustrates the more specific danger of allowing a constructive organising concept to displace detailed treatment of the doctrine under consideration.

Several qualities distinguish the most dependable approaches. First, they establish conclusions through sustained attention to biblical language, argument, and context. Second, they preserve the diversity and progressive development of revelation without abandoning canonical coherence. Third, they distinguish explicit teaching from reasonable theological inference and more speculative construction. Finally, they remain willing to reconsider attractive formulations when significant biblical evidence resists them.

These qualities are especially evident in the strongest work of Calvin, Vos, Ridderbos, and Bavinck, although none should be treated as immune from criticism. They are also found in important portions of Barth and Pannenberg and in Moltmann’s most compelling treatments of resurrection and new creation. Strawn’s sensitivity to literary plurality, Goldingay’s insistence on hearing the Old Testament in its own voice, Childs’s attention to canonical context, and Thiselton’s engagement with interpretation and doctrinal reasoning each contribute something indispensable to the task.

The most productive reading strategy is therefore comparative. Barth’s doctrine of Scripture benefits from engagement with Calvin, Vos, Ridderbos, and the commentators on the relevant biblical texts. Pannenberg’s historical and philosophical synthesis should be examined alongside detailed Pauline and Johannine exegesis. Moltmann and Höhne are best read with the commentaries on the resurrection passages, 1 Peter, Matthew 25, and Revelation 20–22. Strawn’s distinctive readings become more valuable when placed beside the textual and literary analyses of Exodus, Psalms, and Kings specialists. Such pairings preserve the theologians’ genuine insights while making their interpretive assumptions visible.

Conclusion: Theology Must Remain Answerable to Scripture

The comparison of biblical and systematic theologies with the major commentaries reveals a consistent pattern. The greatest theological works do more than repeat exegetical observations: they discover relationships, develop conceptual clarity, and bring biblical teaching into conversation with enduring intellectual and spiritual questions. Their achievement lies in making the breadth and coherence of Scripture more intelligible.

Their weakness emerges when a governing theological idea begins to determine what a passage must mean, when plausible inference is presented as demonstrated teaching, or when difficult biblical evidence is absorbed into a system without receiving its proper weight. Barth’s account of revelation, Pannenberg’s comprehensive historical theology, Moltmann’s vision of universal reconciliation, and Strawn’s imaginative literary readings are very different enterprises, but all illustrate this possibility.

The enduring value of Calvin, Vos, Ridderbos, and the best biblical commentators is not that they avoid theological commitments or imaginative reasoning. It is that their strongest work permits Scripture to question and refine those commitments. The same principle should govern the reading of every theological tradition, including our preferred one.

The task of theology is not to make Scripture conform to the most compelling system we can construct, but to construct the most faithful understanding we can of what Scripture actually teaches. The closer theology remains to the biblical texts, the more confidently its genuine insights can be received—and the more clearly its speculative extensions can be recognised.
