Read your OWN link, Ebb. Even it never says Luther removed 7 books of the Bible! Placing them in a section (like Jerome and others did long before him) is not "removing" them. In fact, Luther translated them into German in his Bible. Here's a link that would help educate you on the topic http://beggarsallreformation.blogspot.com/p/luther-and-canon-of-scripture.html.
Seven books of the Bible, all in the Old Testament, are accepted by Roman Catholics and Eastern Orthodox, but are not accepted by Jews or Protestants. These include 1 and 2 Maccabees, Judith, Tobit, Baruch, Sirach, and Wisdom, and additions to the books of Esther and Daniel. These books are called Deuterocanonical by Catholics and Orthodox and Apocryphal by Jews and Protestants. These were the last books of the Old Testament written, composed in the last two centuries B.C. Their omission in Protestant Bibles leaves a chronological gap in salvation history.
In the 16th century, Martin Luther adopted the Jewish list, putting the Deuterocanonical books in an appendix. He also put the letter of James, the letter to the Hebrews, the letters of John, and the book of Revelation from the New Testament in an appendix. He did this for doctrinal reasons (for example: 2 Maccabees 12:43-46 supports the doctrine of purgatory, Hebrews supports the existence of the priesthood, and James 2:24 supports the Catholic doctrine on merit). Later Lutherans followed Luther’s Old Testament list and rejected the Deuterocanonical books, but they did not follow his rejection of the New Testament books.
Finally, in 1546, the Council of Trent reaffirmed the traditional list of the Catholic Church.
You can tell the Roman Catholic talking points that keep getting recycled. Next we’ll hear about the discredited account of 30k denominations.....or has the number increased?
