The pericope of the “woman caught in adultery” is beloved and well-known. And yet, it does not appear in the oldest manuscripts of John’s Gospel. When it is found in older manuscripts it is located in other positions, either after verse 36, or after verse 44, or at the end of this Gospel, or even in another gospel: following Luke 21:38. 

We are left to conjecture that the biblical scribes thought it too important to be lost but had little clue as to its proper location. Further complicating the provenance of the passage, the different manuscripts do not agree on the text either. In addition, some scholars hold that the style of writing is not consistent with the remainder of the gospel. Other don’t disagree, but hold that the passage is too short with limited vocabulary to make definitive judgements about the stylistic quality. But most, if not all, would agree that the spirit of the narrative is compatible with the Johannine message. It is also noted that the passage does not fit well into the context of Chapter 7 while noting 8:12 makes for more logical continuation following 7:52.

Throughout the history of the church it has been held that, whoever wrote it, this little story is authentic. It is referred to by the late 1st century bishop Papias who was a student of St. John the Evangelist. It is also mentioned in the Apostolic Constitutions (2.24). 

If you look closely at your bible you will likely see brackets ([ ]) surrounding the passage with accompanying footnotes referencing its uncertain manuscript history. The Catholic Church has long held it to be part of the Canon of Scripture.
