The internal evidence for the verses is compelling. Looking back at John 7:37-52, we note that two hostile parties crowded the Temple courts (vv.40-42). Some were for laying violent hands upon Jesus (vs.44). At the same time, the Sanhedrin disputed among themselves privately in closed chambers. Some were reproaching their servants for not having taken Jesus prisoner (vv.45-52).
How then could John have proceeded "Again therefore Jesus spake unto them, saying, I am the light of the world"? What are we supposed to imagine that John meant if he had penned such words immediately following the angry council scene?3
Hills rightly observes that the rejection of the pericope leaves a strange connection between the seventh and eighth chapters: "the reader is snatched from the midst of a dispute in the council chamber of the Sanhedrin back to Jesus in the Temple without a single word of explanation."4 If the pericope is left between these two events, it accounts for the rage of the leaders having been temporarily diffused through the encounter over the woman such that the narrative beginning at 8:12 could transpire without being so out of place. Though their hatred for Jesus remained, the pericope incident brought its intensity down until the following confrontation.
To this we add Jerome's testimony (c.415) "in the Gospel according to John in many manuscripts, both Greek and Latin, is found the story of the adulterous woman who was accused before the Lord."5
We ask the reader's indulgence over the space allotted to this explanation, but the author deemed it necessary to so do in order that you may better judge whether this story be Scripture. The 1611 translators may or may not have understood the account; regardless, they faithfully penned it without detraction.
