Funny that the "New Light" comes in the form of a willingness to scuttle a problematic account which long has been accepted for millenia now, but suddenly is not up to snuff since the WTBTS correctly perceives the account as being problematic for their DFing and shunning policies:

Granted, NT scholars have long known the account is a late addition (it likely appeared in the margin in earlier texts, but was included into the body as time went on, long-ago promoted into the Book of John).
Great, but scholars have ALSO long-known that the epistle of 2nd Peter is unquestionably a fraudulent work, written LONG after Peter was dead: I wonder why it wasn't dropped from the revised NWT, as well? HINT: the book of 2nd Peter fits their theology and practices, whereas John 8 clearly DOESN'T.
Check out my blog articles on Genesis vs 2nd Peter, as it pertains to "righteous" Lot and Noah's preaching work before the Flood:
