Mark did. How do we know that? We know that because we have a perfect Bible called the Pure Cambridge Text of the King James Bible. I open my bible, I look at the book and it has a title; The Gospel According To St. Mark. It really is that simple. I believe my bible. I know people who don't believe the titles. Somebody told them that the titles aren't part of the scripture. How sad that somebody told them that! It wasn't the Spirit of God who told them. He stands by the book as it is delivered to the people.
I started with Mark because I never met a King James Bible believer who didn't believe that Mark wrote the book. Why do they believe it? The sad thing is that they believe it because of tradition, the early church fathers, and the fact that no fundamentalist seriously questions it. Therefore they don't question its authorship. Yet, if we were to ask people who wrote the Book of Hebrews, many would balk. I know that Paul wrote it. I didn't figure that out because of internal proofs, doctrinal harmony, or linguistic parallels. I figured that out because of a big clue. The title says; The Epistle Of Paul The Apostle To The Hebrews.
I know that I just lost some of you. I don't really care. I have a bible and I believe its words, its verse markings, it subscripts and its titles. I am like Jonathan. I have dipped my sword in the forbidden honey and it has enlightened my eyes. Just how much of the book do you believe? Some people tell me that they only believe the actual text in between the titles, verses markings and subscripts. They have no authority for that. One of the purposes of this blog is to cut the chains off of men who been told that their bibles are not 100% reliable. I hope that helps some of you.
