Missing: John 7:53-8:12 (Major)
Manuscripts
The Story of the Adulterous Woman (John 7:53-8:11): Also known as the Pericope Adulterae, this passage describes Jesus encountering a woman accused of adultery and his famous statement, "Let him who is without sin cast the first stone." This story is absent in many early manuscripts of the Gospel of John.

Misquoting Jesus p. 64-65:
"Despite the brilliance of the story, its captivating quality, and its inherent intrigue, there is one other enormous problem that it poses. As it turns out, it was not originally in the Gospel of John. In fact, it was not originally part of any of the Gospels. It was added by later scribes. How do we know this? In fact, scholars who work on the manuscript tradition have no doubts about this particular case. Later in this book we will be examining in greater depth the kinds of evidence that scholars adduce for making judgments of this sort. Here I can simply point out a few basic facts that have proved convincing to nearly all scholars of every persuasion: the story is not found in our oldest and best manuscripts of the Gospel of John; 18 its writing style is very different from what we find in the rest of John (including the stories immediately before and after); and it includes a large number of words and phrases that are otherwise alien to the Gospel. The conclusion is unavoidable: this passage was not originally part of the Gospel. How then did it come to be added? There are numerous theories about that. Most scholars think that it was probably a well-known story circulating in the oral tradition about Jesus, which at some point was added in the margin of a manuscript. From there some scribe or other thought that the marginal note was meant to be part of the text and so inserted it immediately after the account that ends in John 7:52. It is noteworthy that other scribes inserted the account in different locations in the New Testament — some of them after John 21:25, for example, and others, interestingly enough, after Luke 21:38. In any event, whoever wrote the account, it was not John. That naturally leaves readers with a dilemma: if this story was not originally part of John, should it be considered part of the Bible? Not everyone will respond to this question in the same way, but for most textual critics, the answer is no.
