Joshua Schooping’s Chapter 9 in “Disillusioned” (titled “Thus Sayest the Church? Irenaeus and Presuppositionalism”) offers a pointed epistemological comparison between Eastern Orthodox and Reformed presuppositionalism, as the author labels them.
Schooping, a former Eastern Orthodox priest who authored “Irenaeus and Orthodox Apologetic Methodology: A Neopatristic Presuppositionalism” (2017) while still within Orthodoxy, here re-evaluates his earlier position from a Reformed vantage point. The chapter is part of the book’s doctrinal critique section and draws on patristic analysis, particularly of Irenaeus of Lyons, to challenge Orthodox claims to ecclesial authority while defending Scripture’s self-attesting primacy. It treats the canon of Scripture as a key test case for epistemic foundations.
Eastern Orthodox Presuppositionalism (“Thus Sayest the Church”)
Schooping characterizes this position as one in which the Eastern Orthodox Church serves as the ultimate epistemic authority and guarantor of certainty. Knowledge of theological truth, including the identification and authority of Scripture, derives from the Church’s conciliar, traditional, or magisterial testimony rather than from any intrinsic qualities of revelation itself. The Church’s word is treated as logically prior, making Scripture’s canonical status and binding force dependent on ecclesial recognition. This framework is described as a “hyper-ecclesiology” in which the institution elevates itself above the divine Word, creating a dependency in which arguments for Scripture’s authority ultimately rest on the Church’s prior authority. Schooping argues that this inverts the Creator-creature distinction and borders on the blasphemous by making God’s self-revelation subservient to human (ecclesial) testimony.
He further contends that appeals to early fathers such as Irenaeus to support this view involve anachronistically projecting later conciliar and imperial ecclesiological developments onto the ante-Nicene period. On Schooping’s reading in this chapter, Irenaeus does not furnish a warrant for an autonomous ecclesial authority as the transcendental ground of certainty but instead points toward apostolic tradition as preserved and normed by Scripture and the rule of faith.
Reformed Presuppositionalism
Reformed presuppositionalism (in the Van Tillian tradition to which Schooping aligns here) holds Holy Scripture, the self-attesting Word of God, as the ultimate, non-dependent presupposition for all certain knowledge and rationality. Scripture does not require external validation by the Church or any other authority; its canonical status and divine authority are recognized through intrinsic marks and its self-testimony. The Church’s role is ministerial and derivative: it submits to and proclaims Scripture rather than conferring authority upon it. This approach uses transcendental argumentation to show that the Christian worldview grounded in Scripture alone provides the necessary preconditions for intelligibility, logic, morality, and knowledge itself. Certainty flows from the infinite, self-revealing God whose Word breaks into human finitude without circular dependence on creaturely institutions.
Comparative Analysis in Bullet Points
· Ultimate Epistemic Authority: Eastern Orthodox presuppositionalism locates final certainty in the Eastern Orthodox Church’s testimony (“Thus Sayest the Church”), thereby grounding ecclesial consensus or tradition as the transcendental ground. Reformed presuppositionalism anchors certainty exclusively in the self-attesting Scriptures as the Word of God, with no higher or prior authority.
· Grounding of Scriptural Authority and Canon: In the EO model, Scripture’s authoritative status is conferred or recognized through the Church’s prior action, rendering the canon dependent on ecclesial judgment. In the Reformed model, Scripture possesses intrinsic authority and self-authentication; reasons demonstrating its divine origin are persuasive in their own right and do not require ecclesial mediation for validity.
· Logical Priority between Church and Scripture: EO presuppositionalism treats the Church as logically prior, such that arguments for Scripture’s canonicity or authority circle back to or rest upon ecclesial authority. Reformed presuppositionalism treats Scripture as logically and ontologically prior; the Church derives its authority from and remains accountable to Scripture.
· Engagement with Patristic Sources (esp. Irenaeus): Schooping critiques EO appeals to Irenaeus as anachronistic, projecting post-Nicene conciliarism and hyper-ecclesiology onto a second-century context. He presents Irenaeus as supporting a scriptural and apostolic norm that aligns more readily with Reformed emphases on written revelation and the rule of faith over autonomous institutional authority.
· Risk of Circularity or Regress: The EO position, on Schooping’s analysis, risks either vicious circularity (justifying the Church by appeal to the Church) or an infinite regress when seeking an ultimate ground for certainty. Reformed presuppositionalism claims to avoid this by positing Scripture as the non-circular, self-attesting foundation that itself provides the transcendental conditions for rational discourse.
· Theological and Anthropological Implications: EO presuppositionalism is charged with functionally subordinating divine authority to creaturely (ecclesial) authority, undermining “sola Scriptura” and the supremacy of God’s self-revelation. Reformed presuppositionalism upholds the Creator-creature distinction by ensuring that all human institutions, including the Church, remain under the judgment and authority of God’s Word.
Engagement with Schooping’s Argument
Schooping’s analysis is marked by methodological rigor, direct engagement with primary sources (particularly Irenaeus and discussions of the canon), and logical consistency in exposing potential vulnerabilities in an ecclesially grounded epistemology. His insider-to-outsider trajectory lends particular force to critiques of anachronism and the dangers of hyper-ecclesiology. The chapter effectively uses the canon question as a diagnostic tool: if Scripture’s authority is truly self-attesting, ecclesial testimony becomes corroborative rather than constitutive.
Critics might note that Eastern Orthodox theology typically presents Scripture, Tradition, and Church as a symbiotic whole rather than a strict hierarchy, with the Church as the ultimate epistemic authority. Schooping’s “hyper-ecclesiology” framing may therefore overstate the case for some Orthodox readers. Orthodox responses to the book have challenged Schooping’s characterizations of ecclesial authority and his treatment of patristic texts. Nonetheless, the argument compellingly illustrates the epistemic challenges inherent in grounding certainty in any historically contingent institution rather than anchoring it in a divinely inspired, self-authenticating text.
Strengths of Reformed Theology’s Presuppositionalism
Reformed presuppositionalism, as articulated and defended in Schooping’s chapter, offers several distinctive strengths. It furnishes a non-circular, transcendental foundation for knowledge that begins with the self-revealing God rather than any human institution, thereby safeguarding divine sovereignty and the primacy of revelation. By affirming Scripture’s self-attestation, it provides an objective, publicly accessible criterion for theological truth that does not depend on the fluctuating consensus or interpretive authority of any particular ecclesial body. This framework coheres with the Reformation principle of “sola Scriptura,” ensuring that all claims, including those of the Church itself, are tested against the infallible standard of God’s Word. It further equips believers with a robust apologetic method capable of addressing the preconditions of intelligibility itself, rendering Christian faith not merely fideistic but rationally defensible on its own transcendental terms. In Schooping’s presentation, these features avoid subordinating the Creator’s authority to the creature while maintaining a high view of the Church as a servant of the Word rather than its lord. This epistemological orientation ultimately promotes humility before divine revelation and consistency in the application of scriptural norms across all areas of thought and life.
Conclusion
Joshua Schooping’s “Disillusioned: Why I Left the Eastern Orthodox Priesthood and Church” (2nd edition) is a concise yet substantive work that combines personal memoir with theological critique. Schooping, who converted to Eastern Orthodoxy and served as a Russian Orthodox priest for five years before departing, recounts his growing disillusionment with key Orthodox doctrines, particularly icon veneration (iconology), excessive Mariology, and an ecclesiology that he argues elevates the Church above Scripture in ways that confuse or compromise the Gospel. While acknowledging the value of Orthodoxy’s Patristic heritage, the book offers a careful analysis of canonical sources to expose what the author sees as formal theological problems, providing Protestant readers and inquirers with analytical tools to move beyond romanticized or superficial assessments of the tradition. Published by Theophany Press (2nd edition, 2022/2023; also issued via Amazon KDP), the paperback carries ISBN 979-8846021334 and is readily available for purchase on Amazon in both paperback and Kindle editions (search “Disillusioned Schooping” or visit https://www.amazon.com/Disillusioned-Eastern-Orthodox-Priesthood-Church/dp/B0B92VGQ23), with additional copies found through other online retailers such as eBay or select independent booksellers.
