A FRESH ANALYSIS OF JOHN 7:53-8:11 WITH A TOUR OF THE EXTERNAL EVIDENCE James Snapp, Jr.
Many writers on the pericope adulterae claim that that section of the book of John should not be considered as part of scripture as there are notes in the margins telling the copyist to skip this section. This book explains that those marks are misinterpreted. That they are not notes to the copyist but notes to the reader of the lectionary reading for Pentecost.
"“in the ordinary Byzantine lectionary – attested in hundreds of Greek copies – the reading assigned to Pentecost consisted of John 7:37-52 plus John 8:12 (this final verse being included in order to end the lection on a positive note).”"
That is the reader of the lectionary for Pentecost reads John 7:37-52 and then to complete the reading skips to John 8:12.
Not that the copyist is to skip the pericope adulterae but only the reader of the lectionary!
