An Apology for Ad Fontes

Before this series asks for your attention, you deserve an account of why it exists

Lutheran laypeople are already encountering textual criticism. It usually arrives uninvited — in a footnote at the bottom of a pew Bible, in a YouTube video, in a college classroom, in a conversation nobody handed them a framework for. “Pastor said something about Mark 16 last Sunday — what’s that about?” “My friend at work says modern Bibles took out verses about the Trinity. Did they?” “I saw a video that said the New Testament has 400,000 errors. Is that true?” These are real questions from real people in real confessional Lutheran congregations — at men’s prayer, during Sunday school, in text messages from college kids. I’ve fielded versions of all of them. And I’ve watched faithful Christians — sometimes the kids of friends, sometimes the friends themselves — get knocked sideways by a video or a podcast they had no framework to evaluate.

This online series exists to hand you that framework. Ad Fontes — Textual Criticism for Lutheran Laity adapts the opening chapter of my book of the same name (first edition, May 2026) into four lessons, each standing on its own, each ending with a small assignment you can do with the Bible already on your shelf.

Call this introduction an apology — in the word’s older sense. The sense Plato used for Socrates, Justin Martyr used for the second-century church, and Melanchthon used for the Augsburg Confession in 1531 does not mean I’m sorry. It means I owe you an account. Before you spend the next month reading a lay series on New Testament textual criticism — written, I should say plainly at the outset, by a confessional Lutheran layman doing translation work between the discipline’s scholars and the people in the pews — you deserve to know why it exists in this form, for this audience. So let me give you the account.

I want to defend two decisions: that this series is written for the laity rather than for pastors and seminarians, and that it is written from a specifically confessional Lutheran posture rather than from the broader evangelical or Reformed treatments already in print.

On writing for the laity

The first decision is the easiest to defend, because the defense lies in the observation this introduction opened with: the questions are already being asked by the laity, and they are being asked in lay language. Pew questions deserve pew answers — careful ones, honest ones, theologically responsible ones, but not answers that require six hundred hours of Greek before they can be heard.

There is a common view that says, if the lay reader cannot read Greek, the lay reader cannot really engage textual criticism. I want to push back gently on that view, because I think it conflates two things. The first is the technical work of weighing manuscript evidence in the original languages — the work the editors of the critical Greek editions do. The lay reader, of course, cannot do that work, and this series does not pretend to teach her to. The second is the logic of textual criticism — the questions it asks, the kinds of evidence it weighs, the theological stakes of its decisions, the framework within which a footnote in the ESV makes sense. That work is fully available in English. What the lay reader needs is not the technical apparatus but the framework that lets her read those tools intelligently.

There is also a confessional reason. The Reformation’s commitment to the Word in the vernacular was not a commitment to dumbing the Word down. It was a commitment to placing the Word in the hands of the people of God so that they might read it, hear it, and confess it. Luther did not translate the New Testament into German so the laity could be passive recipients of pastoral interpretation; he translated it so the laity could be active readers of the Word their pastors preached. The priesthood of all believers means lay Christians have not just the right but the calling to read their Bibles attentively — including the parts of their Bibles that pose questions.

And the practical reason cannot be ignored. Greek takes years; the questions are not waiting years.

On a confessional Lutheran treatment

The second decision is almost as easy: there is good textual-critical literature in print for the lay Christian, and almost none of it is written from within the confessional Lutheran tradition.

I do not say this to disparage what exists. Daniel Wallace and his colleagues at the Center for the Study of New Testament Manuscripts have done magnificent work — in this writer’s judgment, the most important lay-accessible service to the discipline in our generation, and this series is indebted to it throughout.1 But the existing books, with rare exceptions, are written from within broadly evangelical or Reformed theological frameworks. They handle the doctrine of inspiration, the doctrine of preservation, and the relation of confession to text in ways that reflect their own traditions — not always in ways that map cleanly onto confessional Lutheran categories.

The Lutheran tradition has its own native resources for this conversation: Pieper’s treatment of inspiration and preservation in his Christian Dogmatics; Robert Preus’s Inspiration of Scripture, with its careful retrieval of the seventeenth-century Lutheran scholastics;2 and the Formula of Concord’s Rule and Norm, which stakes the church’s confession on what the prophets and apostles actually wrote:

The prophetic and apostolic writings of the Old and New Testaments are the only rule and norm according to which all doctrines and teachers alike must be appraised and judged.

— Formula of Concord, Epitome, Rule and Norm3

When we say “the prophetic and apostolic writings,” we mean the actual words those prophets and apostles wrote. So when the question comes — “Do we still have those actual words? How do we know? What about the places where the manuscripts don’t all match?” — that is not an idle question. That is a question our confession itself raises and demands an answer to.

And here is a fact worth noticing: confessional Lutherans have, by and large, already trusted this work. Most of our congregations read from the ESV; many came up on the NASB or NIV. All of those translations are based on the critical text of the Greek New Testament — an edition of the Greek that takes into account all the manuscript evidence we now have, including manuscripts the King James translators in 1611 didn’t have access to. Our church bodies — AFLC, AALC, ELS, LCMS, WELS — are not KJV-only. When the ESV came out, our pastors and congregations did not anxiously ask, “Are these still the real words of Jesus?” They trusted, and rightly, that the translators were faithful and the underlying Greek was sound.

What this series wants to give you is the why behind that trust. Not blind trust — trust with reasons.

What this series hopes to do

There is a pastoral reason for doing it this way, too. Confessional Lutheran laity, encountering textual-critical questions, deserve to encounter them in the idiom of their own confession. The Lutheran lay reader who reads a popular evangelical book on textual criticism is being asked, often without realizing it, to absorb that book’s confessional framework along with its textual-critical content. Sometimes the framework imports easily; sometimes it does not. It is healthier to engage the discipline within your own confession’s categories first, and then to engage cross-confessionally from a settled place. That is what this series tries to provide.

Here is the shape of the study — four lessons, each standing on its own:

  1. You’ve been doing textual criticism for years — the footnotes you’ve been skipping, and what they’ve been quietly telling you.
  2. The Reformers were textual critics — Luther, Erasmus, and why ad fontes is our instinct, not our enemy.
  3. The 400,000 variants problem — the number that haunts every conversation about the New Testament, and what it actually means.
  4. Confident on better grounds — the ending of Mark, and what inspiration and preservation actually promise.

Each lesson is drawn from chapter 1 of the book. If the series serves you, the full journey — fifteen chapters, from the scriptorium to the Comma Johanneum to the confessional Lutheran doctrine of Scripture — is in Ad Fontes: Textual Criticism for Lutheran Laity. The lessons, assignments, glossary, and fully annotated references all live here in the Ad Fontes study center.

Soli Deo gloria.
