I never said I don't believe in Limbo. What I said was:
"I was taught Limbo was only used before the resurrection and ascension and is now closed."
Oh, for crying out loud, I clearly meant that you do not believe in a Limbo that continues to exist today, a place where unbaptized infants go.
So, now that we've dispensed with the word games, what do you believe happens to unbaptized infants? If you reject Limbo, you have to say that they either end up in Heaven or in Hell. That's not acceptable to the vast majority of Catholic theologians for the reasons cited in that snipped from Catholic Encyclopedia.
