Here is a hypothetical case:
A feral child (man) somehow overcomes the hardships of life and survives in the wilderness. Because he was abandoned when he was very young, his knowledge of the spoken language is very limited. He is sort of like a Tarzan character. He is of good nature and when he looks at nature he realizes that there must be a God who has created him and all that he sees. God, not to be outdone in His charity, sends him a priest near the end of his life. The priest instructs him on the most important things, the Trinity, the Incarnation, and the Redemption and plans to instruct him more the following day, as it does not seem that death is imminent. The priest goes to see him the next day and finds him dead.
Could that man be saved by BOD? If so, did the individual have an implicit desire or an explicit desire for the sacrament? Obviously, a case like this is far fetched and I’m sure that it most likely never happened, but it does focus on the need for the explicit knowledge of the Trinity, the Incarnation, and the Redemption and not the explicit knowledge of the sacrament of Baptism. I say that in a case like this, the person would only need to have an implicit desire for the sacrament. What do you think?
BTW: I’m sure most of you would say that if God sent a priest to instruct him on his deathbed, He certainly would have made sure that the man received baptism. I would probably agree with you. 😀
