Scrivener can be quoted: “We need not hesitate to declare our conviction that the disputed words were not written by St. John: that they were originally brought into Latin copies in Africa from the margin, where they had been placed as a pious and orthodox gloss on ver. 8: that from the Latin they crept into two or three late Greek codices, and thence into the printed Greek text, a place to which they had no rightful claim.”10
