The reason that most Protestants seem to be against praying for the dead is that they feel that it is useless, as most of them believe that one's fate is sealed at the time of death. However, if one truly comes to the conclusion that God exists outside of time and space as we know it, then why would it not be possible for God to use our prayers after the death of a loved one, retroactively in a sense, and perhaps offer a soul a chance at salvation at the moment of their death? Also, we cannot totally exclude the possibility that there might be some sort of intermediate state after death for some souls. I personally believe that such is probably true, not for everyone, but for some Christians and probably for some non-Christians. Jewish tradition certainly supports the idea of an intermediate state, though they limit it's time length to one year maximum. We all know that Purgatory is deeply rooted with Catholic doctrine and tradition. The Eastern Orthodox do not define how prayers for the dead help, but they do believe that they are valuable. The bottom line is that we cannot know for certain what happens after death. We do not know if prayers help, but they sure cannot hurt. We do know that the practice of praying for the dead goes back to the early days of the Church, so the early Christians apparently dismissed any possible connections of the practice to Necromancy.
