Besides, he throws things together so chaotically that it seems to me he must have been some good, pious man, who took a few sayings from the disciples of the apostles and thus tossed them off on paper. Or it may perhaps have been written by someone on the basis of his preaching. He calls the law a “law of liberty” [1:25], though Paul calls it a law of slavery, of wrath, of death, and of sin.
Moreover he cites the sayings of St. Peter [in 5:20]; Love covers a multitude of sins" [1 Pet. 4:8], and again [in 4:10], “Humble yourselves under he had of God” [1 Pet. 5:6] also the saying of St. Paul in Galatians 5[:17], “The Spirit lusteth against envy.” And yet, in point of time, St. James was put to death by Herod [Acts 12:2] in Jerusalem, before St. Peter. So it seems that [this author] came long after St. Peter and St. Paul.
In a word, he wanted to guard against those who relied on faith without works, but was unequal to the task in spirit, thought, and words. He mangles the Scriptures and thereby opposes Paul and all Scripture. He tries to accomplish by harping on the law what the apostles accomplish by stimulating people to love. Therefore I cannot include him among the chief books, though I would not thereby prevent anyone from including or extolling him as he pleases, for there are otherwise many good sayings in him. Therefore I will not have him in my Bible to be numbered among the true chief books, though I would not thereby prevent anyone from including or extolling him as he pleases, for there are otherwise many good sayings in him. One man is no man in worldly things; how then, should this single man alone avail against Paul and all Scripture.
Concerning the epistle of St. Jude, no one can deny that it is an extract or copy of St. Peter’s second epistle, so very like it are all the words. He also speaks of the apostles like a disciple who comes long after them [Jude 17] and cites sayings and incidents that are found nowhere else in the Scriptures [Jude 9, 14]. This moved the ancient Fathers to exclude this epistle from the main body of the Scriptures. Moreover the Apostle Jude did not go to Greek-speaking lands, but to Persia, as it is said, so that he did not write Greek. Therefore, although I value this book, it is an epistle that need not be counted among the chief books which are supposed to lay the foundations of faith.
So many Catholics object to the authority assumed by Luther to do such a thing… asserting he had no authority to do such a thing.
