I'm from an Orthodox Jewish background and then became a Traditional RC. In the process of studying Orthodoxy, I learned that the Orthodox Church does not believe in the idea of purgatory (although they do pray for the dead).
I know that the original, most ancient Christian Church arose out of first century Judaism, and naturally, would have many similarities to ancient Judaism.
Here is my question: Ancient (and modern) Judaism believed in the idea of purgatory, though its not called by that name. Jews pray for the dead so they can enter the olam ha'ba (Heaven) faster. In the meantime their souls await in a place of purgation, to be loosed from the guilt due to their sins.
Roman Catholics also have this same belief, which is why they, too, pray for the dead.
So, why don't the Orthodox believe in a place of purgation if they are the oldest Church?
