So you would say that the story of paying for the sins of those slain found in 2 Maccabees 12 is in agreement with the rest of scripture? After all the sins were worshipping idols but the teaching is that if you pay enough money after that person is dead you can buy their forgiveness. Do you say that agrees with the rest of scripture?
I will have to read that story to give you an answer. What Chapter and verse? Also, that book is Deuterocanonical, which means it is not used for doctrine, but for teaching.
