It comes to mind that those who support the limbo of the infants of St. Thomas Aquinas need to wrestle with a key question; it is a question that it would seem the Angelic doctor did not consider.
We must remember there are two judgments: the immediate particular judgement, and the general judgement.
The particular judgement is what we experience immediately upon death. The general judgement is what we experience bodily and at the end of this world with the coming of Christ.
It seems that the Angelic doctor's teaching on limbo takes seriously only one of these judgments: the particular judgement. That is, the intermediate state of the dead before the Resurrection. In the intermediate state of the dead, the damned do experience various degrees, and perhaps KINDS of suffering. However, in the general judgement, ALL the damned share one common suffering, one common KIND of torment, the lake of Fire.
Apocalypse 20: 11-15
11" And I saw a great white throne, and one sitting upon it, from whose face the earth and heaven fled away, and there was no place found for them. 12 And I saw the dead, great and small, standing in the presence of the throne, and the books were opened; and another book was opened, which is the book of life; and the dead were judged by those things which were written in the books, according to their works. 13 And the sea gave up the dead that were in it, and death and hell gave up their dead that were in them; and they were judged every one according to their works. 14 And hell and death were cast into the pool of fire. This is the second death. 15 And whosoever was not found written in the book of life, was cast into the pool of fire."
This is apparent because death itself and Hades, that is, the abode of the dead which is the intermediate state of the dead and the damned, are cast into the lake of fire along with Satan and all those who are already damned.
So we must ask a serious question:
If the souls of the unbaptized infants are forever deprived of the vision of God (Everyone agrees with this), and if Limbo is itself a part of Hell (anyone who has read the Angelic doctor will agree with this) then it is INEVITABLE that those ressurected souls who were once infants who are brought before the general judgement, CANNOT IN ANY WAY escape the common fate of Satan and his angels and all the rest of the damned. Why? Because their names are NOT WRITTEN IN THE BOOK OF LIFE:
That is, they MUST be subject to the eternal and sensible punishment of the lake of fire.
This brings up another point: It would be unjust for God to trade a lighter suffering for infants for a greater one when they have done nothing more to merit a greater suffering.
However, since it is inevitable the infants will be sensibly tormented in fire at the END of the world, it does NOT stand to reason that they deserve to be in anything less NOW. Otherwise, where is the justice of God?
Why would soul of the unbaptized infant get such a rude awakening?
But if LIMBO is in itself debatable (and it is, since there are two other perfectly orthodox explanations) then IT must bow to any inconsistencies in the reasons given for its existence. The primary reason Limbo must be done away with is because it implicitly DENIES the truth of scripture: That ALL the damned are tormented together in fire with the Devil at the end of the world.
NOW we begin to see what St. Augustine was so furious over: It is plain and manifest to all that the damned will be sensibly tormented forever with the Devil. It is also plain that infants are damned, since limbo is a part of Hell. Those in Hell are not written in the book of life.
Now, to grant them natural happiness is to turn away the justice of God: for it makes him out to be a monster who allows the souls of unbaptized infants a gentle ignorance (ignorance is bliss) for a time (until the world's end) only to awaken them to the horror of their condition in the general Resurrection!
This is not justice, and is against the Fathers, the dogmatic teaching of the Church, and scripture. Perhaps now we can understand why the African synod of Carthage condemned any such blessedness and declared that the souls of the unbaptized infants run to the left with the devil. Incidentally, this synod was promulgated by two Popes and two ecuмenical councils.
Remember the Final day.
