What so many people don't understand is that:
(1) limbo was never a "dogma," it was a speculation about a question that didn't seem to have a definitive answer. It was some theologians' way of saying, "Well, God is just, and this is what we think could be a just solution: eternal natural happiness of the innocent children."
(2) It implied no pain or punishment, but an eternal fulfillment of the childrens' natural capacities for satisfaction.
The idea was, they can't endure the Beatific Vision because they haven't been "born again," but simply as beings possessing a human nature, they could enjoy an eternity of natural joys.
It's a speculative idea, but not a bad idea.
It doesn't seem like anything to leave the Church about--- not if you understand that the Church was founded by Christ as a key part of His salvation plan for you and for the whole world.
Well said. :)
