Every materially significant variant in the New Testament - what changed, when it changed, and whether the timing tracks the hardening of Christian orthodoxy.
The word forgery barely applies. Almost nothing here is fraud; it is scribal habit - eye-skips, harmonising one gospel to another from memory, liturgical padding, and a smaller set of theologically motivated touch-ups. Only that last set is what you'd call deliberate, and even it isn't deception so much as devotion with a pen.
So the two ratings below measure the answerable things. Materiality (1-10) asks whether the meaning actually moves if the reading changes. Certainty-secondary (1-10) asks how confident the manuscript evidence makes us that the reading is a later addition or alteration rather than original. A ★ marks readings where "added later" versus "deliberately removed later" is genuinely contested, so the certainty figure is held loosely.
The new dimension - timing - sorts every change into one of three date-clusters. The whole point of the exercise is that they don't all line up with the doctrinal narrowing the same way. One cluster tracks it tightly. One tracks it only at second hand. One arrives a thousand years too late to have been part of it at all.
The events along the top are the milestones of "the narrowing" - the process by which a diverse early movement hardened into a single orthodoxy and a closed canon. The coloured bars beneath are the three clusters of textual change. Read the overlap: the Christological cluster sits squarely inside the age of the controversies; the canon-driven cluster shadows the fixing of the fourfold gospel; the late-Latin cluster floats off entirely to the right, in the world of Jerome's heirs and Erasmus's press.
Sorted by materiality. Tap a cluster to isolate it and watch which rows light up - the highest-materiality changes at the top are mostly blue and gold, not red. That pattern is the headline finding, and it's visible before you read a word of analysis.

Yes - but only one cluster does, and it isn't the famous one. The changes split cleanly by date, and the split is the answer to your question.
These are made during the live fights - against adoptionism, docetism, separationism, and early Arianism - and they lean toward the position that would win. "God was manifest" hardens the incarnation; "nor the Son" gets deleted because it armed the Arians; the bloody sweat answers the docetists who denied Jesus could suffer; "forgive them" may have been cut as the church's quarrel with Judaism sharpened. This is Bart Ehrman's Orthodox Corruption of Scripture in miniature, and it correlates with the narrowing tightly - because it is the narrowing, happening at the level of the pen.
These don't answer doctrinal controversies; they answer a structural pressure created by the narrowing. Once Irenaeus fixed the gospels at exactly four (c.180), scribes felt the four ought to agree - so they smoothed Luke's prayer toward Matthew's, gave Mark the resurrection ending its silence lacked, and pulled verses across from one gospel to plug gaps in another. The correlation is real but indirect: harmonisation is a downstream effect of canon-closure, not of Christology. This cluster holds the heaviest changes - Mark's ending, the adulteress.
The Comma and Erasmus's back-translations are doctrinally aligned with orthodoxy - the Comma is a Trinity formula - but they arrive a millennium after Nicaea. This is not orthodoxy forming; it is orthodoxy already settled and being read back into the Greek, first through the Latin West and then through a printing press under theological pressure. It correlates doctrinally and not at all temporally.
Strip it to one sentence: the changes that most clearly correlate with the doctrinal narrowing are the ones that matter least, and the changes that matter most correlate with it only sideways. The Christological cluster genuinely tracks the rise of orthodoxy - but it's a set of low-stakes touch-ups to a text whose theology was already fixed by multiple attestation. The high-stakes additions are about a closing canon and a completing narrative, not about winning a Christological argument.
And the deepest point is the one that has shadowed every turn of this analysis: both the narrowing and the corruption peak in the second century - the very century that sits before our manuscript trail begins. We watch the controversies through the church fathers and we watch the text through 3rd-century-and-later copies, and by the time we can read the manuscripts directly, the proto-orthodox text is already largely in place. So the tightest correlation between text and doctrine lives precisely in the window collation cannot light. We infer it; we cannot photograph it.
The "narrowing" frame is powerful but contested, and an even-handed segment should carry both voices rather than hand a listener one side as settled fact.
Early Christianity was plural before it was orthodox; "heresy" was sometimes the original or majority form in a region. As the Roman-centred form won, scribes during the 2nd-3rd-century controversies altered texts to support the emerging position - adoptionist, docetic, separationist, and patripassianist "corrections" are detectable across the tradition. The text bears the fingerprints of the fight.
The proto-orthodox text was largely stable; the theologically motivated variants are a small, often ambiguous subset, and most differences are plainly accidental. Ehrman's own conclusion concedes the decisive point - no major doctrine actually depends on a disputed reading. Orthodoxy did not need the corruptions, which is hard to square with a picture of orthodoxy manufacturing its scripture.
