Studies in the Epistle to the Hebrews

Who wrote Hebrews? Is it for us to be certain in regard to its human author, and is it of any importance that we should know, since the letter comes to us anonymously? If God meant us to know the author’s name would He not have told us? These are questions properly raised, and I desire to try to answer them in all fairness.
I write for those who believe in the inspiration of this Epistle, as of all Scripture, and by that term I mean all that was accepted as Scripture in our Lord’s day, that is, the entire Old Testament; and also the books regarded as canonical by the Christians of the first century. Hebrews belongs to this latter collection. This is evidently an integral part of the Word of God. Cut from our Bibles, it would leave a great gap that nothing else could fill. In its own place, it fills that gap admirably and forms in a most marvellous way the connecting link between the economy of the Old and the New Testaments.
