I think the two of you are confusing the Limbo of the Fathers (aka Abraham's Bosom) with Limbo for the unbaptised innocents. Two different ideas. The first is well founded doctrine. The latter has always been theological speculation.

I'm well aware of the distinction, but I mainly brought up the Limbus Patrum in answer to Protestants who were claiming there was no Scriptural support for same.
In any case, you're both right and I should be more careful to make the distinction.
I have always frankly considered those given to overt partisanship on the Limbo of the Fathers overly prone to weakness on the filioque clause.
Of course, the Two Limbos to which you allude are the same Limbo. The Fathers no doubt dandle the Holy Innocents upon their aged and arthritic knees. The "Two-Limbo" Theory, which I construe as a dangerous and heretical doctrine, must be stamped out at all costs.
Sure, and I get it. My Limbo gets all Vatican support withdrawn. Yours rolls merrily on? I am going to Rome on this one, pal. Two Limbos, indeed. Where did you pick up that one? Avignon?
