Now, I have major doubts about the existence of Purgatory and I see that Limbo has now all but been eliminated by the church. And I find it hard to imagine a loving God maintaining a hellishly hot hell forever. Maybe those real evil people - Hitler and such - just die dead. Then, again, Hitler was baptized a Catholic. Now if he genuinely repented the very last second, after taking the suicide pill, what happens then? Hell, purgatory, heaven?
Okay. Of course, heaven will be full of good folks of all faiths. All varieties of Christians, Jews, Muslims, Buddhists, Hindus, etc. Jesus will get them through the Pearly Gates, the true meaning of 'no one cometh unto the Father but by me.' I'm not sure about Christians like Mussolini, Jews like Madoff, Muslims like bin Laden, etc. I do know that I spent time living with a Hindu family in India some years ago, and if they don't make it I'm not sure very many of us will get in. They were better 'Christians' than many who claim to be faithfully followers of Jesus. They certainly loved God and their neighbors.
Perhaps you've heard the old joke. Some Protestants, newly-arrived in heaven, were being escorted to their new celestial quarters. St. Peter was accompanying them up the elevator to the 7th floor. "Only one thing," St. Peter asked, "when we pass by the 4th floor please be very quiet. That's where the Catholics are and they think they're the only ones here."
