What will you believe about limbo if the theologians, instructed by Pope Benedict, reject the tentative belief in such a state?
"cannot be denied, having behind it both antiquity from Patristic times"
Regardless of what St. Gregory, St. Thomas Aquinas, or Pope Pius VI "believed", did that really, really make it an absolute fact? And how does having antiquity behind it prove anything? Belief that the earth is flat had antiquity behind it, to mention one example.
The earth is not flat.
Do you have a primary source for this bizaar assertion? :)
It is not a dogma of the Church. What is dogma is the importance of baptism. The unbaptised are literally in limbo, because we do not know where they are, but then we don't know where most of the dad are. We have signs only about the saints.
