Wrong.
Luther edited and corrupted your Bible. When he did, he removed 2 Macc 12:45, which says that it's a "holy and pious thought" to pray for the dead.
Jews prayed for their dead then, did so in Jesus' time (he had no problem with it), and do so now. Luther could remove Scripture he didn't like, but he doesn't get to edit facts.
All Christians except Protestants pray for their dead. The Greeks do, the Russians do, the Armenians do, etc. You guys are the odd man out, because you're in thrall to a set of rationalistic errors invented in the 16th Century by rebels who were the antithesis of "conservative" in every respect.
Prayer for the dead implies a state, condition, or event after death in which they can be helped by our prayers. That can't be heaven; nobody in heaven needs our help, rather, we need theirs. It can't be hell, because those in hell are beyond help. It can only be some middle condition of judgement or purgative (there's that word) cleansing.
Paul knew this when he wrote in 1 Cor 3:15 of those whose works were faulty, who could nevertheless be saved, but "only as through fire". Look it up. It's in your Bible.
BTW, if I say a prayer or two for my dead father on Father's Day, exactly how does that keep me "enslaved to ... religion"?
I don't have a Luther bible...
But c'mon...There's so many errors in your added books to the bible that there is no way they were inpired by God..
