The Author of 21 of the Gospel

The author of chapter 21 wanted to position himself, if you will, the voice of the author of chapters one through 20. He makes it very clear that it's the disciple whom Jesus loved, who has written these things up to and including his section of the book. But for strategic reasons, he decided to slip back into that we to bring together the testimony of all these eyewitnesses. And then he ends up with the I at the end.
