Thank you for correcting me.
I appreciate that a contrition of a forgotten sin may be impossible but the honest and explicit intention to recall all and confess them, is required. I cannot obtain absolution if I confess without this explicit desire to recall all sins and obtain absolution for all sins, even those that I forget. Or, at lest, this is what I am being taught. Explicit intention is key.
But my point was that, if an explicit intention is key for confession, then also an explicit intention must be key for baptism.
This would open the possibility of Bod to a very limited number of cases (*)1 and confirm the exclusion for souls who: (a) know of Christianity and of the sacrament of baptism but do not explicitly desire it or have the explicit intention and (b) do not even know of the existence of Christianity and the sacrament of baptism and therefore have no explicit intention.
(*)1 a soul who knows about the sacrament of baptism and explicitly desires it but dies before he can obtain it.
Indeed, you have to have sincere contrition for and the intention to confess every mortal sin; in other words, you can't be deliberately hiding or holding back on any.
Certainly, if there is such a thing as BoD, then I believe that an explicit intention would be necessary. If you look at what Trent taught about Confession, initially the text read that perfect contrition sufficed to restore a soul to justification. But the Pope, inspired by the Holy Spirit, intervened and insisted that the condition also of intending to confess the sin be added as necessary. And that is what Trent taught infallibly. Certainly the intention to confess could be read implicitly into perfect contrition. I mean, if you're perfectly contrite, then you implicitly also would intend to make whatever act of reparation God requires, including Confession. So this notion that the intention to confess would be implicit in perfect contrition was rejected by Trent for Confession. So why should we imagine that an implicit intention could suffice for Baptism ... when Trent taught that it does NOT suffice for confession? There's no reason to believe this, and it's a huge stretch. So you raise a very important point that I had not completely thought through before.
PS ... too many Traditional Catholics falsely believe that one need only have perfect contrition to be restored to a state of justification. But Trent teaches that this does not suffice but must be combined with the intention to confess those sins as soon as it is reasonably possible.
I've used this analogy before, for Baptism, but it also applies to Confession. We have a man who loves a woman deeply, proposes (and she accepts), sets a date, rents out a hall, sends out invitations, and schedules everything with the priest. But now, 5 minutes before the actual vows, he gets cold feet and bails out. Despite ALL his intentions, he was never married. So, with Confession also ... and Baptism. I can be deeply sorry, but unless I intend (vow, even) to go to Confession, then I'm not really sorry and am not restored to a state of grace (per Trent). And, so also with Baptism. Even if one believes that Trent taught BoD, the word Trent uses is
votum, which in Medieval Latin meant a solemn vow (like the ones pronounced at marriage or by a religious) ... and our word "vow" derives from this word as well. There is no indication anywhere among the Church doctors or in the Magisterium that BoD can ever apply to anyone other than a catechumen.
