The Self-Attesting Word versus Ecclesiastical Circularity: A Presuppositional Refutation of the Charge that Sola Scriptura Is a Logical Fallacy
Abstract
Roman Catholic and Eastern Orthodox apologists frequently allege that the Protestant formal principle of “sola Scriptura” commits a logical fallacy, typically “petitio principii” (begging the question) or an illicit appeal to a document whose canon and meaning are said to be products of the Church. This article contends that the charge misconstrues both the nature of ultimate authority and the structure of Reformed epistemology. Drawing on Gordon H. Clark’s Scripturalist axiom and Cornelius Van Til’s doctrine of the self-attesting Christ of Scripture, it argues that every worldview begins with an unprovable first principle. The relevant question is which axiom yields a coherent, non-contradictory system. Scripture, received as the verbally inspired Word of God, is that axiom. By contrast, the Roman and Orthodox positions begin with the Church (or with an extra-scriptural deposit of Tradition whose content and interpretation the present Church alone infallibly determines) and terminate with the Church. That is a more vicious circularity. The Church recognizes the canon; it does not constitute it. Scripture’s authority depends “not upon the testimony of any man or Church, but wholly upon God.”
I. The Charge and Its Logical Form
The standard critique runs as follows. Protestants appeal to the Bible as the sole infallible rule of faith. Yet the Bible’s table of contents was fixed by ecclesiastical councils; its text was copied and transmitted by the Church; and its meaning is disputed among those who claim to follow it. Therefore, the Protestant must tacitly rely on an extra-scriptural, infallible authority, the Church, in order to possess Scripture at all. To deny that authority after using it is inconsistent. Moreover, because Scripture nowhere contains an inspired table of contents or an explicit statement of “sola Scriptura” in those words, the doctrine is either self-referentially incoherent or an extra-biblical tradition smuggled in under protest.
Some recent Catholic presentations raise a more formal objection: arguments that move from “Scripture is inspired” to “only Scripture is an infallible rule” commit the fallacy of denying the antecedent because inspiration and infallibility are not logically identical. An uninspired but Spirit-guided magisterium could, in principle, be infallible.
These objections seem formidable only if one accepts two assumptions: (1) that an ultimate authority can be justified by something more ultimate than itself, and (2) that the Church’s historical reception of the books is equivalent to the Church’s “constitution” of their authority. Both assumptions are false.
II. Axioms, Circularity, and the Inevitability of a Starting Point
Gordon H. Clark repeatedly observed that every system of thought must begin somewhere. By definition, an axiom is not deduced from a prior proposition; otherwise, it would not be first. Empiricism presupposes the reliability of sensation. Rationalism presupposes the sufficiency of unaided reason. Roman and Orthodox ecclesiology presuppose either an infallible, living magisterium or an unbroken, extra-scriptural Tradition, whose precise content the present hierarchy or the consensus of bishops alone can declare. All such starting points are formally circular. The question is never whether circularity exists at the foundation, but which circle is vicious and which is the necessary condition of intelligible thought.
Clark’s axiom is therefore not “God exists” in the abstract; Spinoza’s “Deus sive Natura” shows how empty that name can be. The determinate proposition is “The Bible is the Word of God.” From that axiom, the remaining doctrines of the system are deduced by good and necessary consequence, precisely as the Westminster Confession of Faith (1.6) requires. Logic itself is not an independent secular principle added to Scripture; it is the characteristic of God’s thinking and therefore already implicit in the axiom.
Cornelius Van Til reached a parallel conclusion by a different route. Because God is the self-existent, self-sufficient Creator, His revelation cannot be authenticated by any created standard that stands outside it. To demand that Scripture first submit to the verdict of autonomous reason, historical criticism, or ecclesiastical decree is to make the creature the measure of the Creator. The Word of God is self-attesting. The identification of Scripture as God’s Word “can be effected no other way than by way of the self-testimony of Scripture,” and it is received “through the testimony of the Holy Spirit to the Scripture as self-attesting.” Any attempt to verify the ultimate by the penultimate inverts the Creator–creature distinction.
Thus, the charge of circularity, when leveled solely against “sola Scriptura,” is special pleading. Every ultimate commitment is circular. The Protestant simply refuses to pretend otherwise.
III. The Self-Attesting Character of Scripture
The Westminster Confession states the matter with classic precision:
“The authority of the Holy Scripture, for which it ought to be believed and obeyed, dependeth not upon the testimony of any man or Church, but wholly upon God (who is truth itself), the Author thereof: and therefore, it is to be received because it is the Word of God.” (WCF 1.4)
The Church’s testimony may induce “a high and reverent esteem,” and the internal marks of Scripture (heavenliness of matter, consent of parts, efficacy of doctrine) abundantly evidence its divine origin. Full persuasion, however, is the inward work of the Holy Spirit bearing witness by and with the Word (WCF 1.5). The supreme judge of all controversies remains “the Holy Spirit speaking in the Scripture” (WCF 1.10).
This is not a late Protestant invention. It is the necessary implication of the doctrine of verbal inspiration. If God has spoken, His speech carries His authority. No creaturely “imprimatur” can add to or subtract from that authority. Van Til insisted that the self-attesting Christ of Scripture is the starting point of all Christian thought; one cannot first establish a neutral platform and then climb to Christ. Clark likewise treated 2 Timothy 3:16–17 and related texts not as theorems to be proved from a prior axiom but as part of the axiom itself.
The Roman and Orthodox claim that the Church “gave us the Bible” confuses two distinct acts: “recognition” and “constitution”. The books were Scripture the moment they were God-breathed. Over time, and with local variation, the Church recognized what God had already given. Councils of the late fourth century did not create canonicity; they registered a reception that had already occurred in the churches. To treat the Church’s recognition as the “source” of authority inverts the order of being.
IV. The Circularity of Starting and Ending with the Church
The Roman and Orthodox positions form a tighter, more problematic circle. The living magisterium (or the consensus of the Fathers as presently interpreted by the bishops) is the infallible interpreter of both Scripture and Tradition. Yet the identity, extent, and meaning of Tradition are themselves determined by that same magisterium. One begins with the Church’s claim to infallible guardianship and ends with the Church’s claim to infallible guardianship. Scripture is admitted to be inspired, but only as read through the lens the Church supplies. The result is that the Church is both the premise and the conclusion.
This is not an incidental feature but a structural necessity for any system that places an infallible extra-scriptural organ alongside or above the written Word. Historical counter-evidence, contradictory papal pronouncements, the “Filioque” controversy, the differing status of the deuterocanonical books between East and West, and the absence of a single universally received “unwritten tradition” on numerous later dogmas must then be resolved by further appeal to the present Church’s authority to define what counts as authentic Tradition. The circle is closed.
Clark’s question remains pertinent: “What? came the word of God out from you? Or came it unto you only?” (1 Cor. 14:36). The apostles did not wait for a later council to ratify their letters. The churches received them as Scripture because they bore the marks of apostolic, God-breathed authority. Subsequent ecclesiastical reception is a significant historical fact; it is not the ontological ground of that authority.
Van Til’s critique of Roman Catholicism is equally relevant here. By ascribing a measure of ultimacy to the Church’s interpretive office and to analogical reasoning that begins with created being, Rome mixes “the clay of paganism with the iron of Christianity.” The self-sufficiency of God and His Word is compromised; human (ecclesiastical) autonomy is granted a foothold that Scripture itself never allows.
V. Sufficiency, Perspicuity, and the Formal Principle
“Sola Scriptura” does not mean “nuda Scriptura” or the rejection of all ministerial tradition. It means that Scripture alone is the “infallible” rule, the “norma normans non normata.” Creeds, councils, and the fathers are valuable insofar as they agree with Scripture; they are corrigible when they do not. The Confession’s insistence that the whole counsel of God is either expressly set down or may be deduced by good and necessary consequence (WCF 1.6) is Clark’s method in confessional form. Van Til likewise refused to isolate the text mechanically from the rest of God’s revelation, while insisting that special revelation supplies the ultimate criteria.
The alleged fallacy of “denying the antecedent” therefore misses the Reformed claim. The argument is not merely “inspired, therefore uniquely infallible.” Rather, it is that only God can speak with absolute, irrevocable authority, that He has done so in the prophetic and apostolic writings now closed, and that no subsequent office has been promised the same charism of inspiration. The historical record of ecclesiastical contradiction provides empirical confirmation of what the axiom already entails.
VI. Conclusion
The accusation that “sola Scriptura” is a logical fallacy rests on a misunderstanding of what an ultimate authority must be. Clark and Van Til, despite their well-known differences on the analogical character of knowledge and the place of paradox, agreed that the Christian must begin with the self-attesting Word. That beginning is formally circular, as every first principle is. It is not vicious because it alone renders the rest of thought coherent and because it corresponds to the ontological fact that God has spoken.
The Roman and Orthodox alternatives begin and end with the Church. They convert a historical instrument of transmission and recognition into an ongoing source of infallible dogma. In doing so, they invert the relation between the speaking God and the hearing Church. The Protestant formal principle simply refuses that inversion. Scripture is received because it is the Word of God, not because the Church has first declared it so. The sheep hear the Shepherd’s voice; they do not first authenticate the Shepherd with an independent ecclesiastical certificate.
Addendum: Patristic Testimonies to the Supreme Authority of Holy Scripture
The following witnesses neither isolate Scripture from the life of the Church nor anticipate every later Protestant formulation. They do, however, treat the written Word as the decisive, sufficient, and highest norm by which doctrine is to be proved, heresy excluded, and even the teaching of bishops tested. In that limited but crucial sense, they stand with the Reformed formal principle rather than with any later claim that an extra-scriptural organ is co-equal or superior in binding authority.
1. Irenaeus of Lyons (c. 130–202)
“We have learned from none others the plan of our salvation, than from those through whom the Gospel has come down to us, which they did at one time proclaim in public, and at a later period, by the will of God, handed down to us in the Scriptures, to be the ground and pillar of our faith.” – “Against Heresies” 3.1.1 (ANF 1:414).
Irenaeus identifies the apostolic preaching, now committed to writing, as the “ground and pillar” of the faith. The Scriptures, not a subsequent unwritten deposit independently guaranteed by succession, are the form in which that preaching reaches later generations as the church’s foundation.
2. Athanasius of Alexandria (c. 296–373)
“The holy and inspired Scriptures are sufficient of themselves for the preaching of the truth.” – “Contra Gentes” 1 (NPNF 2/4:4).
And after listing the canonical books:
“These are fountains of salvation, that they who thirst may be satisfied with the living words they contain. In these alone is proclaimed the doctrine of godliness. Let no man add to these, neither let him take ought from these.” – “Festal Letter” 39.6–7 (NPNF 2/4:552).
Athanasius, who defended Nicaea, nevertheless locates the proclamation of godliness “in these [books] alone” and forbids addition or subtraction. The sufficiency claimed is material and normative, not merely decorative.
3. Cyril of Jerusalem (c. 313–386)
“For concerning the divine and holy mysteries of the Faith, not even a casual statement must be delivered without the Holy Scriptures; nor must we be drawn aside by mere probabilities and the artifices of argument. Even to me, who tell you these things, give not absolute credence, unless you receive the proof of what I set forth from the Divine Scriptures. For this salvation which is of our faith is not by ingenious reasonings, but by proof from the Holy Scriptures.” – “Catechetical Lectures” 4.17 (NPNF 2/7:23).
The catechist of Jerusalem explicitly subordinates his own teaching office to scriptural demonstration. The hearer is not to believe the bishop “absolutely” unless the bishop’s words can be shown from Scripture.
4. Gregory of Nyssa (c. 335–395)
“We are not entitled to such license, I mean of affirming what we please; we make the Holy Scriptures the rule and the measure of every tenet; we necessarily fix our eyes upon that, and approve that alone which may be made to harmonize with the intention of those writings.” – “On the Soul and the Resurrection” (NPNF 2/5:439; the words are placed on the lips of Macrina and endorsed by Gregory). Cf. “Against Eunomius” 1.22.
Gregory states the formal principle with unusual clarity: Scripture is the “rule and measure” of every doctrinal assertion. What cannot be shown to harmonize with it is not to be approved.
5. John Chrysostom (c. 349–407)
“And with good cause He calleth the Scriptures a door, for they bring us to God, and open to us the knowledge of God, they make the sheep, they guard them, and suffer not the wolves to come in after them. For Scripture, like some sure door, barreth the passage against the heretics, placing us in a state of safety as to all that we desire, and not allowing us to wander… For he that useth not the Scriptures, but climbeth up some other way, that is, who cutteth out for himself another and an unusual way, the same is a thief.” – “Homilies on the Gospel of John” 59.2 (on John 10:1; NPNF 1/14:213).
Elsewhere Chrysostom insists:
“If anything is said without Scripture, the thinking of the hearers limps… But when the testimony of the divine voice proceeds from Scripture, it confirms both the speech of the speaker and the mind of the hearer.” – Commentary on Psalm 95 (PG 55:247; cf. the citation in Jeremy Taylor, “Ductor Dubitantium”).
And:
“Look for no other teacher; thou hast the oracles of God; none teaches thee like them.” – “Homilies on Colossians” 9 (NPNF 1/13:304).
Chrysostom’s pastoral practice matches the principle. He treats the written oracles as the door of the sheepfold, the bar against heresy, and the teacher than which none is greater. Those who invent another way of access are thieves.
These five voices, spanning Gaul, Egypt, Palestine, Cappadocia, and Antioch/Constantinople—do not constitute a sixteenth-century confession. They do demonstrate that the conviction that Holy Scripture is the highest, sufficient, and self-attesting rule of faith is not an innovation of the Reformation but a recurring patristic judgment. The later Roman and Orthodox elevation of an infallible extra-scriptural organ must therefore be measured against this earlier consensus, not simply assumed to be its authentic continuation.
