Limbo is a speculative idea about the afterlife condition of
those who die in original sin without being assigned to Hell of the
damned meaning those who died before Jesus came to earth.
I had read more about Limbo, apparently there is the Limbo of
the Fathers and the Limbo of Infants.
The latter is a hypothesis about the permanent status of the
unbaptized who die in infancy, too young to have
committed personal sins, but not having been freed from original
sin.
I believe only Catholics believe in this (?) and limbo also
exists in other religions like Islam and Zoroastrianism.
I don't know about limbo. What I was told is babies
die end up in heaven coz they are newly born, no sins found in them
that is why can go up heaven.
