I believe that "Catechumens who, through no fault of their own, die without Baptism, are to be treated as baptized."
Since the grace of baptism (rebirth/regeneration) does not occur in BoD, I am up in the air on this now.
The logical fallacy employed here is a "Red Herring" , distracting the discussion through a false premise (i.e. "Since the grace of baptism (rebirth/regeneration) does not occur in BoD") followed by a boastful lack of conformity to Church teaching.
Trent session 6, CHAPTER III.
Who are
justified through Christ.
"But, though He died for all, yet do not all receive the benefit of His [Page 32] death, but those only unto whom the merit of His passion is communicated. For as in truth men, if they were not born propagated of the seed of Adam, would not be born unjust,-seeing that, by that propagation, they contract through him, when they are conceived, injustice as their own,
-so, if they were not born again in Christ, they never would be justified; seeing that, in that new birth, there is bestowed upon them, through the merit of His passion, the grace whereby they are made just...."
Trent Session 5, On Original Sin #5
"...
For, in those who are born again, there is nothing that God hates; because, There is no condemnation to those who are truly buried together with Christ by baptism into death; who walk not according to the flesh, but, putting off the old man, and putting on the new who is created according to God, are made innocent, immaculate, pure, harmless, and beloved of God, heirs indeed of God, but joint heirs with Christ;
so that there is nothing whatever to retard their entrance into heaven. So the grace of baptism DEFINED by Trent is to be reborn/regenerated. The theory of BoD
as taught by St Thomas and St Alphonsus does not eliminate the temporal punishment due to sin, which is contrary to the infallible definition.
That is why I said I was up in the air about it. To debate in favor of BoD you MUST contend that the Catechumen was reborn and had all temporal punishment due to sin washed away too. This obviously would repudiate the Saints on the theory.
