The problem was this:
No one can be damned who is not guilty of personal sin.
No one can be saved without Baptism.
Therefore: What happens to those who die without personal sin, and without Baptism?
Limbo, a state of natural happiness, without the Beatific Vision. I.e., a place or state that is neither Heaven nor Hell.
So you created a 'state' that the bible doesn't reference...You invented a 'state' to fill in the hole that your theology created...
Seem to me that with all the intellectuals in your religion someone at some time would have said, 'wait a minute', maybe we're looking at this thing wrong...Maybe we're mis-interpreting a few things...Maybe we're skipping some scripture that covers this problem...
Since you reject the theory of Limbo (which, BTW, was never the teaching of the Church, only a theory), it is fair to ask:
What do YOU say happens to unbaptized babies who die?
Are they saved or damned?
