Be Careful Interpreting Biblical Facts

Some modern scholars have decided that Paul didn't write all the books normally attributed to him. For a discussion of this you should read What Paul Meant by Garry Wills. I personally am not convinced by his arguments.

The question of whether or not Paul wrote Hebrews is a different matter. I don't think he did. He always put his name into his letters as a way to stress the teaching authority of his letters, but no name is attached to "To the Hebrews.(ΠΡΟΣ ΕΒΡΑΙΟΥΣ)"

The book reads as a scholarly and well-written, logically constructed essay; Paul's letters read like they were poured out of the intellectual volcano that was Paul. He was, after all a Pharisee, and his letters sound like a preacher speaking extemporaneously, throwing out question after question, piling paradoxes on top of one another, sometimes sarcastically insulting his opponents, sometimes sounding gentle and fatherly. Just when he seems like he may go too far, he pulls back and asks "does this mean?" questions. His repeated answer; "God forbid!"

One of the arguments used to decide that Paul didn't write Hebrews is the fact that the book uses 112 Greek words that are not found anywhere else in the New Testament.

Moses Stuart (1780-1852), an attorney, pastor, and linguist (Hebrew, Syriac, Greek, and German) countered this argument with the fact that everyone agrees that Paul wrote 1 Corinthians yet it contains 230 words found nowhere else in Paul. In other words, the unusual words in Hebrews probably prove nothing about its authorship.

The non-Pauline author most commonly mentioned for Hebrews is Apollos (Acts 18:24-27; 1 Corinthians 3:4-6, 16:12, Titus 3:13). The fact that no writer's name is placed on the book has led some to think it may have been written by a woman.
