In the Catholic view, the Protestants deleted these books; in the Protestant view, the Catholics added them. Historically, they were part of the Greek Old Testament (the Septuagint), which was translated into Greek circa 250BC. The Jews, after the destruction of Jerusalem in 70 AD, repudiated the Septuagint at their council of Jamnia ~ 90AD, basically throwing out any of the later books. Writing with living memory of this council, St. Justin Martyr’s “Dialog With Trypho”, the earliest surviving apologetics tract addressing Jews specifically, records:
“But I am far from putting reliance in your teachers, who refuse to admit that the interpretation made by the seventy elders who were with Ptolemy[king] of the Egyptians is a correct one; and they attempt to frame another. And I wish you to observe, that they have altogether taken away many Scriptures from the translations effected by those seventy elders who were with Ptolemy, and by which this very man who was crucified is proved to have been set forth expressly as God, and man, and as being crucified, and as dying; but since I am aware that this is denied by all of your nation, I do not address myself to these points, but I proceed to carry on my discussions by means of those passages which are still admitted by you.” (chapter LXXI)
Read Wisdom 2 for a great example of why the Jews, after Christ, might want to delete this book from their canon.
