Bern,

Limbo is not, nor ever was, an official Catholic doctrine though for centuries was widely accepted as true. It was a theoretical solution to the problem of unbaptized catechumens and innocents, those who died with no personal sin. They didn't deserve Hell but couldn't enter Heaven because they didn't meet one or more of Christ's criteria, e.g. Baptism.

We hold that God can save those who have not been formally baptized just as He can save anyone who seeks Him with as earnest heart and soul but has not received sufficient teaching or the sacraments to know the full Gospel. It is called Mercy.

God's salvific will extends to all (cf. 1 Timothy 2:3) and affects more than just believers. (cf. 1 Timothy 4:10).

Limbo is unnecessary and obsolete as a theological construct.

Peace,
