Authorship: what the texts themselves claim
None of the four Gospels names its author inside the main narrative — the titles ("According to Matthew," etc.) are early but were attached to the manuscripts, not written by the authors into the text itself. That matters: the case for authorship rests partly on external tradition (church usage from the second century onward) and partly on internal signals, and the two kinds of evidence need to be kept distinct.
John is the clearest case of internal self-testimony. John 21:24 states directly: "This is the disciple who testifies about these things, and wrote these things (ὁ γράψας ταῦτα — ho grapsas tauta, from γράφω/1125, 'wrote'). We know that his witness is true." The verse identifies the author as "the disciple" mentioned just before (traditionally the Beloved Disciple), and the "we know" is the voice of a community vouching for him — likely an editorial note appended by those who circulated the Gospel, distinguishing the eyewitness's testimony (μαρτυρῶν, from μαρτυρέω/3140) from their own confirmation of it. This is the Gospel making an explicit claim to eyewitness authorship, not a later inference readers have drawn.
Luke is candid about being the opposite of an eyewitness account at first hand. Luke 1:2 says the material was "delivered to us" by "those who from the beginning were eyewitnesses (αὐτόπται, autoptai/845 — literally 'self-seers') and servants of the word." Luke identifies himself as a compiler of eyewitness testimony, not as one of the eyewitnesses himself — a distinction the text draws on its own terms.
Mark and Matthew carry no comparable internal claim in the passages given here; their authorship rests on external tradition (Papias, Irenaeus) that isn't part of this corpus and can't be adjudicated from these texts alone.
Why "eyewitness" mattered to that culture
Luke 22:71 shows the weight a firsthand hearing carried in this world: "Why do we need any more witness? For we ourselves have heard from his own mouth!" Direct testimony settled a matter; secondhand report did not. That's the standard the Gospels are held to, and the standard Luke explicitly invokes for his own sources.
Where the disagreement actually lies
Historical-critical scholarship widely holds that all four Gospels are anonymous compositions, later attributed to apostolic names to lend authority, and dates them decades after the events partly on the assumption that theological development implies late composition. That's a real scholarly position, but the theological-development premise is doing a lot of work — it assumes reflection takes generations rather than granting it could happen within eyewitnesses' own lifetimes. Read as scripture, the church has taken John's self-attestation and Luke's stated method at face value, because nothing in the text itself requires distrusting them, and the external tradition supporting Matthew and Mark is early and consistent rather than contested from within.

From the interpretive tradition
The evidence for our New Testament writings is ever so much greater than the evidence for many writings of classical authors, the authenticity of which no one dreams of questioning.
The Scriptures are the product of the Spirit of God, and are therefore in the highest and truest sense the Word of God, though given through the instrumentality of men.
In the Catholic Church itself, all possible care must be taken that we hold that faith which has been believed everywhere, always, and by all.
