[Peter666]

Back to limbo. I made my case above with all the dogmatic sources, so if you have any specific questions regarding those, I'll be happy to answer.

We don't know for certain if Limbo exists, as this is theological speculation. But it is de fide heresy to condemn anyone who holds this opinion. And we also know that salvation is impossible for the unbaptized (in one of the three forms). If they don't go to a type of "limbo" then the only alternative is a really mild Hell. That was St. Augustine's speculation. We will know for certain in the afterlife.

As for the last Pope, we do not know JP II's exact position on the salvation of unbaptized infants through the CCC. He did not write the CCC, although he authourized it. However, from his fairly vast theological writings, it appears he believes in a general efficacious salvation that was merited to man simply by the incarnation of Christ, thus elevating man's dignity. The sacrifice of Christ on the Cross was not in itself necessary, but an act of love. This helps us understand all of JP II's theology and it follows that this belief would bring about the other errors such as false ecumenism.

It will have to be a future Church Council and Pope that will go through the details in all their intricacy to make official pronouncements of condemnation. This is not unprecedented: it happened twice before in Church history with two other Popes. But they only had one little issue, where JP II engrosses all of Catholic thought with his errors.
