I was just a kid when I first saw limbo dancers bend back a scoot themselves under a thin pole nearly walking on their ankles. When I started Catholic school, I learned of a new type of Limbo that had nothing to do with dancing.
Because of the concept of "Original Sin," which makes all humans born guilty of the "sins of the father, in this case, Adam and Eve every child born into the world has a black mark on their soul for something they didn’t do. In the case of Catholics, newborns undergo baptism as soon as possible to erase the stain of original sin.
You with me so far? Now, it gets weird. Infants that died before a chance for baptism were SOL. But wait! Along comes Limbo for infants, which was a place on the suburbs of Hades. It wasn't Hell, but just on the outskirts.
Since I graduated Catholic School, I was there for Chubby Checker’s classic “Limbo RocK” that asks the burning question, “How low can you go?” After sitting through endless Baltimore Catechism classes, it became clear the Marianas Trench was a bit shallow for the depth of Catholic apologetics and just plain old “cover your ass” follow-ups.
What I finally grasped was Limbo acted as a staging area until liftoff with the Second Coming of Christ. By the way, Limbo is not part of Catholic Canon Law, nor is it mentioned in the Bible. In fact, Limbo is a Catholic "do over" for a fill-in the blanks theology that let one slip through the cracks.
There is far more to the history of Limbo. However, the entire subject is moot other than a Catholic curio as the Vatican decided the bar was too low to continue the Limbo and sent it off in an unceremonious fashion to the graveyard of stupid ideas.
Note: Seven generations is long past and curse of Yaweh has passed the Statute of Limitations.
