The end of the world is coming soon. Probably within the next eighty years. For you. While discussing the idea of the rapture (but not who will or won't be left behind) is an important task for a Catholic apologist to engage in, the far bigger issue is your own salvation.
"How do I get to Heaven?" Is it with faith alone? Is it faith and works? Does it really matter? Is there a heaven at all?
Let great Catholic theologians like James Akin and Saints like St. Alphonsus Liguori show you the straight and narrow path.
If you are still interested in learning about the end of the rest of the world, you're still in the right place.
