John 21:24

24. This is the disciple Spoken in John’s usual manner of himself, in the third person.

We know Speaking in full apostolic and inspired authority for and with the apostolic Church. From that Church, the gifted Church, endued with the discerning of spirits, we receive the sacred canon, and thereby amply prove that its books were selected under divine guidance. Even if the authors were not inspired, this testimony of the then living Church fully establishes the New Testament as the authentic announcement of the facts and doctrines of Christ’s religion. That the apostle here passes into the plural number, we know, is a dignified assumption of representative character, in communion with that Church.
