Well why don't we ask Martin Luther himself what he thought about the Book of James, before he declared that it was not scripture and attempted to remove it from the Bible?
WORKS OF MARTIN LUTHER - PREFACES TO THE BOOKS OF THE BIBLE
PREFACE TO THE EPISTLES OF SAINT JAMES AND SAINT JUDE 1545 (1522)
Though this
Epistle of St. James was
rejected by the ancients, I
praise it and hold it a good book, because it sets up no
doctrine of men and lays great stress upon God’s
law. But to
state my own opinion about it, though without injury to anyone, I consider that it is not the writing of any
apostle.
My reasons are as follows.
First: Flatly against St. Paul and all the rest of Scripture, it ascribes righteousness to works, and says that Abraham was justified by his works, in that he offered his son Isaac, though St. Paul, on the contrary, teaches, in Romans 4:2, that Abraham was justified without works, by faith alone, before he offered his son, and proves it by Moses in Genesis 15:6. Now although this Epistle might be helped and a gloss be found for this work-righteousness, it cannot be defended against applying to works the saying of Moses in Genesis 15:6, which speaks only of Abraham’s faith, and not of his works, as St. Paul shows in Romans 4. This fault, therefore, leads to the conclusion that it is not the work of any apostle.
Second: Its purpose is to
teach Christians, and in all this’ long teaching it does not once mention the Passion, the Resurrection, or the Spirit of
Christ. He names
Christ several times, but he
teaches nothing about Him, and only speaks of common
faith in
God. For it is the
duty of a true
apostle to
preach of the Passion and Resurrection and
work of
Christ, and thus lay the
foundation of
faith, as He Himself says, in
John 15:27, “Ye shall bear witness of me.” All the genuine
sacred books agree in this, that all of them
preach Christ and deal with Him. That is the true test, by which to
judge all books, when we see whether they deal with
Christ or not, since all the Scriptures show us
Christ (
Romans 3:21), and St.
Paul will know nothing but
Christ (
1 Corinthians 15:2). What does not
teach Christ is not apostolic, even though St. Peter or
Paul taught it; again, what
preaches Christ would be apostolic, even though
Judas, Annas,
Pilate and
Herod did it.
But this James does nothing more than drive to the
law and its works; and he mixes the two up in such disorderly fashion that it seems to me he must have been some good, pious man, who took some sayings of the apostles’
disciples and threw them thus on paper; or perhaps they were written down by someone else from his
preaching. He calls the
law a “law of
liberty,” though St.
Paul calls it a
law of
slavery, ( of
wrath, of
death and of
sin (
Galatians 3:23;
Romans 7:11).
Moreover, in
James 5:20, he quotes the sayings of St. Peter, “Love covereth the multitude of sins” (
1 Peter 4:8) and “Humble yourselves under the
hand of God” (
1 Peter 5:6), and of St.
Paul (
Galatians 5:10), “The Spirit lusteth against hatred”; and yet, in point of time, St. James was put to
death by
Herod, in
Jerusalem, before St. Peter. So it seems that he came long after Sts. Peter and
Paul.
In a word, he wants to
guard against those who relied on
faith without works, and is unequal to the task [in spirit, thought, and words, and rends the Scriptures and thereby resists
Paul and all Scripture], and would accomplish by insisting on the
Law what the
apostles accomplish by inciting men to
love. Therefore, I cannot put him among the
chief books, though I would not thereby prevent anyone from putting him where he pleases and estimating him as he pleases; for there are many good sayings in him.
Friend, you have to admit that you are on pretty shaky ground when the most famous Protestant in history, and the one primarily attributed to developing the modern Protestant doctrine of "salvation by faith alone," himself concluded that the book of James contradicts his theology (hence his need to throw it out of the Bible).
Good luck with that, seriously.
