Vatican to review state of limbo

Ever heard of the theory of limbo? I hadn't. From an article of the same title on BBCNews.com:

For centuries many Roman Catholics have believed that the souls of babies who die before baptism remain in limbo. But the concept has never been part of official Church teaching, and it is thought Pope Benedict may be keen to do away with it… The theory of limbo was expounded in the Middle Ages as a solution to the theological question over what happened to the souls of babies who had not been cleansed by baptism of the "original sin" Catholics believe is inherent in all humanity, but were too young to have committed any sins of their own. Limbo has also been held to be the final destination for people who lived virtuous lives before the time of Christ. It is not certain whether this teaching is likely to be changed… The Catholic Church is usually very tenacious about its beliefs and does not change its teaching lightly… However, Benedict, who before he became Pope was the Church's top authority on doctrine, is known to be keen to tie up loose theological ends… ...some have suggested that the possible change is an attempt by the Vatican to prevent people in developing countries with high infant mortality rates turning to Islam - Muslims believe the souls of stillborn babies go straight to paradise.
