You're missing the point. Whether or not "Abraham's Bosom" remains (as a place) is different from whether it is USED (as a holding place for people). Some say the Garden of Eden still remains (as a place), but it's no longer used (except for maybe Enoch/Elias...waiting for antichrist...but it's not USED in the same way as Adam/Eve used it).
The purpose of Abraham's Bosom was a temporary place of waiting til one can get to heaven...it was a waiting room for Christ. It is no longer used for that purpose, as there is no longer anyone from the Old Testament who is "justified" but unbaptized. And there is no longer a wait for a Redeemer. So, with the termination of the Old Law, so the purpose of the OT Limbo is terminated.
St Thomas' comments on whether or not the place still remains, is irrelevant to my point. The purpose is gone.
You said "the Limbo of the just was temporary." That statement does not conform to what Aquinas said. Can you at least admit that your opinion differs from St. Thomas Aquinas?
Regarding the "purpose" of the "limbo of the Fathers," here is Aquinas's response to Objection 2 (just below the earlier quote I provided), Aquinas says:
Reply Obj. 2: The place of rest of the holy fathers was called Abraham’s bosom before as well as after Christ’s coming, but in different ways. For since before Christ’s coming the saints’ rest had a lack of rest attached to it, it was called both hell and Abraham’s bosom, wherefore God was not seen there. But since after the coming of Christ the saints’ rest is complete through their seeing God, this rest is called Abraham’s bosom, but not hell by any means. It is to this bosom of Abraham that the Church prays for the faithful to be brought.
If you will read Aquinas carefully, I think you will see that
the purpose of the "limbo of the just" does not go away after the Resurrection of Christ, and therefore, as Aquinas says there is nothing that prevents the "limbo of the just," called Abraham's bosom, from still being there "after Christ's coming."
Just as you are incorrect about "the limbo of the Fathers," you are incorrect about "the Garden of Eden," aka Paradise. That is still the place of reward for the saints who overcome in the end times.
St. John makes it clear that Paradise will be the destination of those who overcome [Apocalyps 2:7]:
7 He, that hath an ear, let him hear what the Spirit saith to the churches: To him, that overcometh, I will give to eat of the tree of life, which is in the paradise of my God.
In his description of the New Heaven and the New Earth, St. John says in Apocalypse chapter 22:
2 In the midst of the street thereof, and on both sides of the river, was the tree of life, bearing twelve fruits, yielding its fruits every month, and the leaves of the tree were for the healing of the nations.
...
14 Blessed are they that wash their robes in the blood of the Lamb: that they may have a right to the tree of life, and may enter in by the gates into the city.
