The Protestants Plea for a Socinian: Justifying His Doctrine from Being Opposite to Scripture or Church Authority

In Short

This work is a structured, five-part intellectual debate between a Protestant and a Socinian—a follower of a rationalist theology that denied the divinity of Christ. The Socinian argues that, according to the standard Protestant doctrines of biblical interpretation and individual conscience, he cannot be condemned as a heretic or a schismatic for his beliefs. The text serves as a sophisticated exercise in logic, exposing the tensions within the Reformation’s claims regarding scriptural clarity and the authority of the church, and it remains a primary document for understanding seventeenth-century religious controversy.

The Story

The dialogue opens with the Socinian asserting that he, like any Protestant, believes the entirety of Scripture to be the Word of God. He contends that his error regarding Christ’s consubstantiality with the Father is merely an error of interpretation, not a rejection of divine authority. He argues that he has used his "best endeavour" to understand the text, and since God would not be so unjust as to damn a sincere seeker of truth for failing to grasp an obscure or complex theological point, he remains a faithful Christian. The Protestant is immediately put on the defensive, forced to articulate why this specific point of faith—the divinity of Christ—is a fundamental necessity that cannot be subject to private judgment in the same way as other, lesser doctrines.

As the debate progresses, the focus shifts to the authority of the Church. The Socinian systematically dismantles the Protestant reliance on the unanimous consent of the Catholic Church. He argues that such consent is historically unprovable and that, even if it existed, Protestants themselves maintain that the Church can err in non-fundamental matters. When the Protestant appeals to the Council of Nicea and the authority of the early Church fathers, the Socinian invokes the writings of various Protestant theologians to argue that no human council possesses the power to compel internal assent. He insists that he is not a schismatic because he has not separated from the body of the Church itself, but merely maintains his own judgment on a point where he finds no clear biblical mandate.

The argument culminates in a detailed examination of the nature of heresy and schism. The Socinian repeatedly pushes the Protestant to define how one can discern a true "fundamental" point of faith from a minor error without resorting to the very institutional infallibility that Protestants reject. The Protestant attempts to bridge this gap by suggesting that while human judgment is necessary, it must be guided by humility and obedience to the established Christian consensus. The Socinian rejects this, arguing that the Protestant position—which allows for the right of private interpretation—inevitably leads to a deadlock where no authority can definitively judge a dissenter. The book concludes with the Protestant urging the Socinian to abandon his "subtle and perilous" pride and return to the shared belief in the Trinity, while the Socinian maintains that he remains a dutiful member of the Church, compliant with all that is clearly required by the text of the Bible.

How It Unfolds

The foundational claim The Socinian establishes the primary premise that sincere, diligent study of the Scriptures fulfills one’s religious duty, regardless of the conclusion reached. He challenges the Protestant to prove that his specific theological error is a matter of salvation-critical necessity.

The test of church authority The conversation transitions to the legitimacy of historical councils, specifically the Council of Nicea. The Socinian argues that if General Councils can err, as Protestants often claim, then he is free to dissent from their definitions if he finds them contrary to his own reading of the Bible.

The accusation of heresy The Protestant attempts to categorize the Socinian’s denial of Christ’s divinity as an obstinate, damnable heresy. The Socinian counters by demanding a definition of heresy that does not rely on the very institutional infallibility the Protestant previously renounced.

The defense against schism The debate addresses the charge of schism, with the Socinian claiming he has not left the Church, but only rejects an erroneous "condition of communion" imposed upon him. He asserts that the true schismatics are those who demand obedience to doctrines not explicitly laid out in the plainest words of Scripture.

The final impasse The dialogue concludes with the Protestant admitting that he cannot provide an objective, non-institutional judge for these disputes. He ultimately retreats to an appeal for the Socinian to cultivate humility, while the Socinian stands firm in his reliance on the private judgment of conscience.

The People

The Socinian acts as the sharp-witted provocateur. He is deeply committed to the idea that religion must be reasonable and that individual conscience is the final arbiter of truth. Throughout the dialogue, he avoids being caught in his own contradictions by constantly mirroring his opponent’s logic back at him, effectively using the Protestant’s own arguments to justify his position.

The Protestant represents the mainstream ecclesiastical authority of the period. He begins with confidence in the clarity of the Scriptures and the wisdom of the early Church, but he is gradually forced to grapple with the instability of those arguments. He struggles to maintain the boundary between the "private judgment" that allowed the Reformation to occur and the "heresy" that he believes the Socinian represents.

By the end of the exchanges, the two remain fundamentally split: the Socinian views himself as a faithful, rational believer who has been wrongly accused, while the Protestant views the Socinian as a victim of a "subtle and perilous" intellectual pride that has blinded him to the essential, non-negotiable truths of the faith.

In Its Own Voice

When discussing the burden of searching for truth, the Socinian defends his individual effort:

I do my best endeavour to believe Scripture in the true sense thereof. By my best endeavour I mean, such a measure of industry, as humane prudence, and ordinary discretion (my abilities, and opportunities, my distractions, and hindrances, and all other things considered) shall advise me unto in a matter of such consequence.

Regarding the danger of being accused of heresy for his interpretation, he notes:

For my error or ignorance in what is not plainly contained in Scripture, after my best endeavour used; to say that God will damn me for such errors, who am a lover of him, and lover of truth, is to rob man of his comfort, and God of his goodness; is to make man desperate, and God a Tyrant.

What It's Really About

At its core, this work investigates the fragility of the "Protestant principle" of individual interpretation. It asks the uncomfortable question: if the individual is the final judge of what the Bible means, how can any institution maintain a coherent set of essential doctrines? The book exposes the tension between the freedom to interpret religious texts and the need for a unified community of faith. It centers on the anxiety that allowing private judgment in matters of secondary importance might inevitably lead to the dismantling of the central pillars of Christianity, leaving the Church with no effective way to define or exclude heresy.

Why Read It Today

Reading this text is an exercise in rigorous, logical interrogation. It is not an easy read; the prose is dense, deeply rooted in seventeenth-century theological dialectic, and peppered with references to councils, synods, and contemporary divines that will require patience from a modern reader. However, those interested in the history of ideas will find it fascinating as a "stress test" of Reformation-era logic. It vividly captures a moment when the intellectual foundations of the modern Western religious experience were being pushed to their absolute breaking point.

What stays with you is the sheer intellectual agility of the Socinian. He does not play the role of a villain or a fanatic; instead, he uses the very tools of his adversary—Protestant reliance on Scripture and the rejection of papal infallibility—to force the reader to confront the inconsistencies of the Protestant position. It is a striking, if dry, window into a culture where questions of dogma were life-and-death matters, and where the boundaries of belief were being redrawn through intense, clause-by-clause argument. If you enjoy historical debates that refuse to settle for easy answers, you will find this a challenging and intellectually stimulating piece of archival evidence.
