John 21

Some reason that John 21 is an addition which was not originally written by John, because:

• Some believe the language and style differs.
• John 20 concludes the witness of Jesus, but John 21 jumps back to another resurrection occurrence which breaks the text's chronological flow.
• John 21 refers to John in the third person.

Although some manuscripts lack John 21, some of the most early manuscripts did include John 21.

A possible explanation is that John as a fisherman was likely illiterate and someone else wrote the Gospel on his behalf and possibly added his own commentary at the end which some might have removed or included depending on the view of the person that copied the text.
