We know that it has been asserted by some critics that this chapter must have been added by another hand, because the evangelist concluded his work in the previous chapter. This, however, is not accepted by sound scholarship, for the reason that it is not unusual in the New Testament writings and in other good books, for authors to insert supplementary matter, to which class the chapter in question clearly belongs. There is no evidence that John's Gospel was ever known in the early Church without this chapter. John, it is true, refers to himself in the third person; but he did so also in chapter 19:35 in practically the same terms as in 21124. The best commentators agree as to the genuineness on prima facie evidence.
