Vince,
Please don’t apologize! There is no need for it.
I was curious myself because I had always heard that St. John the Apostle did in fact write both the book of Revelation AND the Gospel.
This well known Catholic website and others state so itself.
newadvent.org/cathen/08438a.htm
It says,
Authorship
If we except the heretics mentioned by Irenaeus (Against Heresies III.11.9) and Epiphanius (Haer., li, 3), the authenticity of the Fourth Gospel was scarcely ever seriously questioned until the end of the eighteenth century. Evanson (1792) and Bretschneider (1820) were the first to run counter to tradition in the question of the authorship, and, since David Friedrich Strauss (1834-40) adopted Bretschneider’s views and the members of the Tübingen School, in the wake of Ferdinand Christian Baur, denied the authenticity of this Gospel, the majority of the critics outside the Catholic Church have denied that the Fourth Gospel was authentic. On the admission of many critics, their chief reason lies in the fact that John has too clearly and emphatically made the true Divinity of the Redeemer, in the strict metaphysical sense, the centre of his narrative. However, even Harnack has had to admit that, though denying the authenticity of the Fourth Gospel, he has sought in vain for any satisfactory solution of the Johannine problem: “Again and again have I attempted to solve the problem with various possible theories, but they led me into still greater difficulties, and even developed into contradictions.” (“Gesch. der altchristl. Lit.”, I, pt. ii, Leipzig, 1897, p. 678.)
A short examination of the arguments bearing on the solution of the problem of the authorship of the Fourth Gospel will enable the reader to form an independent judgment.
Direct historical proof
If, as is demanded by the character of the historical question, we first consult the historical testimony of the past, we discover the universally admitted fact that, from the eighteenth century back to at least the third, the Apostle John was accepted without question as the author of the Fourth Gospel. In the examination of evidence therefore, we may begin with the third century, and thence proceed back to the time of the Apostles.
I thought this was interesting and I thought you would too.
God Bless,
