Protestants can We clear something up here?
Second The Catholic Old Testament follows the Alexandrian canon of the Septuagint the Old Testament which was translated into Greek around 250 B.C. The Protestant Reformers follows the Palestinian canon of Scripture (39 books), which was not officially recognized by Jews until around 100 A.D.
Prior to Jesus’ time, the Jews did not have a sharply defined, universal canon of Scripture. Some groups of Jews used only the first five books of the Old Testament (the Pentateuch); some used only the Palestinian canon (39 books); some used the Alexandrian canon (46 books), and some, like the Dead Sea community, used all these and more. The Palestinian and Alexandrian canons were more normative than the others, having wider acceptance among orthodox Jews, but for Jews there was no universally defined canon to include or exclude the “deuterocanonical” books around 100 A.D.
The Apostles commissioned by Jesus however, used the Septuagint (the Old Testament in Greek which contained the Alexandrian canon) most of the time and must have accepted the Alexandrian canon. For example, 86 percent of Old Testament quotes in the Greek New Testament come directly from the Septuagint, not to mention numerous linguistic references. Acts 7 provides an interesting piece of evidence that justifies the Apostolic use of the Septuagint. In Acts 7:14 St. Stephen says that Jacob came to Joseph with 75 people. The Masoretic Hebrew version of Genesis 46:27 says “70,” while the Septuagint’s says “75,” the number Stephen used. Following the Apostles' example, Stephen clearly used the Septuagint (We also know from other ancient Christian documents, like the Didache and Pope St. Clement’s Letter to the Corinthians, that the apostles’ successors not only used the Septuagint, but quote from all of the books in the Alexandrian canon as the authoritative word of God.)
So your opinion of these seven books is very wrong, and in these books it clearly states that we should pray for our dead, so that's not all you have wrong.
Seems truth is of no importance, but the lie must be defended, really it's like talking to Atheists.
I find great value in it, verse15 and 20
speak volumes, how you reject it as not authentic i really don't know.
