Thinking God's Thoughts: The Promise of Proof-texting for Dogmatic Formation

This article originated as a theology paper written as part of my studies with Union Theological College in Spring 2026.

“In its most general sense proof-texting is the practice of pulling an authoritative text out of its original context to impose upon it a meaning that advances the interpreter’s thesis.”[1] This definition succinctly summarises a common view. Likewise, from an historical perspective, Carl Trueman observes many assume “seventeenth century theology was built on a rather crude system of proof-texting, whereby texts were seized in isolation and used to prove doctrinal positions that had already been assumed.”[2] This assignment rejects such assumptions by arguing that a revised and renewed practice of proof-texting promises significant benefits for dogmatic formation. It begins by defining a revised and renewed practice based on an historic approach. It then highlights three reasons why this is so promising, arguing it: (1) repeats the method of Scripture, (2) reflects the shape of Scripture, and (3) respects the nature of Scripture.

The Practice of Proof Texting

Proof-texts are “parenthetical references or footnote/endnote references to biblical passages that undergird some doctrinal claim made, whether in a dogmatics text, a catechism, or a confession of faith.”[3] While it is historically common, the practice has more recently been critiqued for lacking sensitivity to literary context, being overly reliant on word studies, and imposing interpretative traditions.[4] While this has sometimes been true, we need not conclude proof-texting should be abandoned.[5] Instead, this essay argues a revised and renewed practice, which returns to the historic approach of the seventeenth century, promises significant benefits.

On this historic approach, Douglas Kelly explains “it was never the intention or the practice of the Protestant scholastics to wrench biblical texts out of their context in Scripture or to dispense with careful biblical exegesis in the original languages.”[6] Similarly, it was not assumed “the meaning of a cited proof text should be self-evident to the reader apart from the hard work of grammatical, historical, literary, and theological exegesis.”[7] For example, the citations in the Westminster Confession were designed to prompt readers to turn to the relevant passages in key commentaries and sermons, as well as in their Bibles.[8] Rather than drawing an isolated point out of a biblical text, proof-texts were supposed to draw a reader back into the biblical context. They were portals through which the reader would “plunge beneath the surface of the text’s discrete assertions.”[9] This aligns with an approach to systematic theology that sees it not as “building on top of Scripture—building a system up taking the various biblical claims as axiomatic—so much as a task of building beneath Scripture—constructing an underlying set of conceptions and distinctions that allows the whole of Scripture to be taken seriously”.[10]

The Promise of Proof Texting

(1) Repeating the method of Scripture

The clearest argument for the promise of proof texting is that it repeats the dogmatic method we find in Scripture. As Michael Allen and Scott Swain provocatively put it, “All of the charges brought against proof texting in Christian theology could be lodged against the Bible’s own use of the Bible.”[11] However, this does not mean such charges would ultimately be justified. For Scripture’s citations contain a wide range of sophisticated connections that are sensitive to the biblical context, go beyond word studies, and expose (rather than impose) interpretations. For example, the fulfilment formula in Matthew’s Gospel not only include Old Testament citations that are relatively straightforward (2:5–7; 4:13–16; 21:4–5), but also those requiring substantial exegetical and typological work to interpret (1:22–23; 2:15; 2:17–18; 2:23). We must avoid the fallacy of “confusing a method of citation with a hermeneutical procedure.”[12] As Richard Muller points out, “A formula such as “it is written” often supports a theological claim... with a richness of context and complex regard for the redemptive-historical situation”.[13]

(2) Reflecting the shape of Scripture

A revised and renewed practice of proof texting also reflects the shape of Scripture. This is firstly true of its exegetical and canonical shape. Rather than a way for theologians to avoid good exegesis, it allows them to refer to a long stream of such work through a single citation. As Muller explains, “The theologians of the seventeenth century certainly did accompany virtually all of their doctrinal formulations...with a battery of citations from Scripture. Yet, when one follows out their citations to the biblical commentaries of the day, one finds that their citations do not represent texts torn out of context but rather their citations point toward what one can only call the “assured results” of the best exegetical methods of the age.”[14] During the era of orthodoxy it was common for theologians to have “spent long portions of their careers as exegetes” and they “viewed study of the Old or the New Testament as the proper preparation for the dogmatician.”[15]The eighteenth-century Baptist, John Gill, is a late yet helpful example of this. Before publishing his influential body of divinity in 1769, Gill spent over 20 years commentating on every verse in Scripture. To grasp the full meaning of his proof-texts, it is important to examine them in his earlier commentary, which in turn refers readers to other passages in Scripture as well as to the works of others.[16] In this way, proof-texting plots a pathway for us across the entire canon, as well as the wider exegetical tradition.

The practice also reflects the theological shape of Scripture. A revised and renewed approach employs both exegetical and dogmatic reasoning when choosing a citation. As R. B. Jamieson and Tyler Whitman explain, “Exegetical reasoning attends to the order and flow of the text,  following its twists and turns, dogmatic reasoning attends to the theological claims of the text, looking along with the text to discern the ultimate reality to which it bears witness.”[17]Proof-texts not only prompt us to ask what a passage says, but also how it says it. This is particularly important for doctrines like the Trinity (e.g. Genesis 1:26; Psalm 110:1) and Christ’s person (e.g. John 10:30; 14:28; Philippians 2:6–7). Such citations do more than draw out the exegetical point in a text. They also highlight the theological pressure exerted by the text. By stressing “the grammar” of Scripture,[18] they sculpt our systems into the same shape.

(3) Respecting the nature of Scripture

Finally, a revised and renewed practice respects the nature of Scripture. As Grant Osborne asserts, dogmaticians must acknowledge “the centrality of one’s conception of Scripture for theological construction.”[19] The nature of Scripture determines our reception of Scripture.[20] To the extent that we understand the Bible to be the inspired and inerrant Word of God, then some form of proof-texting is inevitable. We believe Scripture is not just “illocutionary (action) and perlocutionary (parenetic) but also lotutionary (propositional) in form and function.”[21] As John Webster put it, “the text is a gift which evokes the works of reason.”[22] However, this “is not an indeterminate intellectual activity, reason in search of an object, but reason to which an approach has already been made with unassailable might, to which an object has been given.”[23] Texts, not topics, are the objects of Christian theology. “Scripture is the place to which theology is directed to find its subject-matter and the norm by which its representations are evaluated.”[24] Proof-texting tethers our theology to the text in a way that respects the reality of what it is.

Conclusion

Herman Bavinck famously claimed, “The imperative task of the dogmatician is to think God’s thoughts after him and to trace their unity.”[25] It is for this reason that a revised and renewed practice of proof-texting, based on the historic approach, is so promising. By repeating the method of Scripture, we imitate the revealed reasoning of the divine mind. Similarly, such citations will reflect the shape of Scripture, stretching us to see the canonical breadth and theological depth of God’s thoughts. Finally, a revised and renewed practice respects the nature of Scripture, ensuring that we treat God’s thoughts as God’s thoughts. For these three reasons, it must not be abandoned, but instead enthusiastically retrieved and reapplied today.
