whether it be formal baptism, baptism of desire or baptism of blood, it still remains that a person must be baptized to enter the kingdom of heaven.
as for speculating about implicit and explicit baptism of desire, i have no problems with it.
however, it does seem a little bizarre to believe that a person who has never heard of the Holy Trinity can after death come to that knowledge.
although, as i stated earlier, Jesus did preach the gospel to the souls of the righteous who died before His Coming.
that teaching however has implications that would weigh against the concept of an implicit baptism of desire. if the righteous who died before Christ needed an after-death encounter before entering the kingdom of heaven, why would they not have experienced an implicit baptism of desire?
perhaps such issues have been resolved to your satisfaction. i find myself not so certain about them.
is the doctrine of an implicit baptism of desire an official teaching of the RCC?
i had never heard of it before reading your post.
