No irony at all. I was responding based on Alamo-girl's idea of how that question could be better phrased. The way it was asked shows a lack of understanding of what the term sola Scriptura means. But had you gone to the link I gave, rather than post a knee-jerk reaction in hope for a gotcha question, it actually does give some internal proof for the Apostle Matthew as the author of the Gospel by his name. Regardless, the Christian belief in the infallible and authoritative, Divinely-inspired Holy Bible is not refuted by appeal to early Christian theologians and writers who uphold the authenticity of each book that makes up our Holy Bible. That you call it "Catholic historical references to prove that a Catholic book in a Catholic Bible is part of the Catholic Canon", doesn't negate the fact that the Christian faith is universal and we are all members of the one Body of Christ, a "Spiritual House" of which we are living stones. The Roman Catholic Church doesn't own the copyright of Christianity.
That is what makes it a real cr@pshoot. There is no one universally accepted definition of "Sola Scriptura", Bart Brewer had his, James White has his own (Which is so all encompassing it hardly mentions the Bible), And Loyd Gypsum of Bible Baptist in my home town has a completely different one.

Actually we pretty much do, but we just don't enforce it with the same vigor that the NFL does.
