One particular objection I heard about the validity of Deuterocanonical books is that, some of its passages contradict the non-Deuterocanonical scriptures, for instance, the prayers for the dead in 2 Maccabees 12:43-45 “is opposed” to Ecclesiastes 9:5-6 which teaches that the dead no longer remember anything and have part in “anything that is done under the sun.” The Easy-to-Read version (which they cite, uhm, I don’t know, for convenience I think) says “The living know that they will die, but the dead don’t know anything. They have no more reward. People will soon forget them. After people are dead, their love, hate, and jealousy are all gone. And they will never again share in what happens on earth.”
One answer I can think of at the moment, which I recall I had read somewhere in the footnotes of the NAB, is that the Hebrew belief on the dead is “evolving”. There was a time when the Hebrews do not believe in the resurrection of the dead, but later on they did. Just not sure about this, and the time “when”. Perhaps I’ll look it up again.
Anyway, how do we reconcile “2 Maccabees 12:43-45” with “Ecclesiastes 9:5-6”, if the opposition is actually true?
