I Believe In Heaven and Hell

I don't get my answer from protestants because they interpret everything to literally. I'm happy with the idea of purgatory and the Catholic church can quote scripture to prove that purgatory exist. I have seen videos and read articles were Catholics and Priest, can pin point where the idea of purgatory comes from. Unlike the doctrine of protestant theology were you are save by faith alone, is a lie. You are save by Faith and works.
