Despite the controversy this group has, I still like to consider the points they present. Plus this idea that the old testament saints could have been baptised is not new to me.

My problem is, the souls of the Just in Limbo only ascended into heaven with their souls, not their bodies; meaning that their souls were united to their bodies for a time immediately after the Resurrection - and only a human person can receive baptism, not a soul divorced from its body - and then these (holy people) were baptized, but then only their souls ascended into heaven.  This is all to say that the holy souls are all in heaven, but their holy bodies must be somewhere on earth, awaiting the General Resurrection.  It is my understanding that the only two persons (body and soul) who are dogmatically in heaven are Christ and his Blessed Mother. 

Not even the great St. Joseph is in heaven body and soul. It is my private opinion that the body of St. Joseph will be discovered during the reign of the antichrist, or immediately preceding the reign of Mary.  Hopefully this makes sense and I have not spoken in error, but this is Catholic theology as I have understood it.   Very interesting video though. Thanks

Elias (Elijah) the prophet was taken up to heaven: 4 Kings 2:1-11.   Elias then appeared bodily next to Our Lord at the Transfiguration: St. Matthew 17:2-3.

In Benedictus Deus, pope Benedict XII solemnly defined that the souls of the just and of the reprobate are judged and given their reward/punishment upon death with no delay. The pope seems to have rather carefully avoided saying anything about the body (other than affirming it will be joined to the soul at the eschaton). Nevertheless, this solemn definition seems to more or less preclude any additional opportunities for justification after actual death.

Not exactly

immediately (mox) after death and, in the case of those in need of purification, after the purification mentioned above,
 
since the ascension of our Lord and Saviour Jesus Christ into heaven, already before they take up their bodies again and before the general judgment, have been, are and will be with Christ in heaven, in the heavenly kingdom and paradise,

It depends on if the old saints need to be purified? And if baptism falls under purification?

Hmm what about the Saints being seen in the city as per Matthew 27:52-53? Did these saints use their bodies again and lose them when entering heaven? Or was their appearance just their soul?

Interestingly, the pope also says in this definition that the beatific vision "does away with" faith and hope (insofar as they are theological virtues) since there is no more need for them. I believe this question came up on another thread recently. If someone dies justified, according to this ex cathedra statement, their soul immediately goes to Heaven where it no longer needs faith or hope (which baptism infuses).

Yeah, when you can see God you can't have faith. As faith is to believe what you cannot see. And who hopes to attain what they already have?

Very good questions. I think Benedictus Deus forbids us from saying that such are "in the wayfaring state", as Yeti/Jone put it. Most likely, I would guess God clothes their soul with a body in a similar way to how he clothed the archangel Raphael, or the angels he sent to warn Lot. In neither case is the person seen truly hylomorphic, at least not with their *own* body.

But consider the story of St. Peter Claver and the negro girl, Augustina (I believe was her name).  She died and at her Particular Judgment she was told that she could not enter heaven because she had not received baptism.  St. Peter Claver then raised her to life, baptized her, and she was able to go to heaven.  So in this particular example, as we understand it, Augustina had an opportunity for justification after death. 

Of course assuming that it's a true story, it is a person under the new law. While it's a nice piece for EENS and water baptism, it's not infallible and doesn't help too much for the old law.

Still it's icing on the cake for me at least.
