Of course. That’s why there was always hope for the unbaptized and people who take their own life. Why was the hopeful half of the message never recognized or spoken about until the 1960’s? Either the Church didn’t know about it or they knew and didn’t want anyone else to know.
Unless I missed understood you, what you said was totally wrong. After death there is no chance for salvation. Our eternity is fixed at the moment of death.
Regarding how God communicates with those not in the state of grace, he does this through actual grace. Sanctifying grace is a “habitus” something that we are clothed with. Actual grace is, what some call, an inspiration of the Holy Ghost.
Regarding those who die in original sin only: they go immediately to hell, but they suffer different punishment than those who have committed actual sin.
Council of Lyons II, 1274: “The souls of those who die in mortal sin
or with original sin only, however, immediately descend to hell, yet to be punished with different punishments.” (Denzinger 464)
**Council of Florence, 1438-1445: **“The souls of those who depart in actual mortal sin
or in original sin only, descend immediately into hell but to undergo punishments of different kinds” (Denzinger 694)
There are two schools of thought on the punishment suffered by those who die in original sin only. According to the school of St. Augustine, they suffer the loss of the beatific vision (the vision of God) and a very slight pain or sense. According to the more common teaching adhered to by St. Thomas and most other theologians, those who die in original sin only, live in a state of perfect happiness, only lacking the vision of God.
The Church knows of no way that a child under the age of reason can attain the state of grace. The only reason there can remain any “hope” that they might, is that there could be some way for God to bring this about… but if there is, the Church does not know about it.
**Pope Eugene IV, Council of Florence: **“Regarding children, indeed, because of danger of death, which can often take place,
when no help can be brought to them by another remedy than through the sacrament of baptism, through which they are snatched from the domination of the Devil and adopted among the sons of God, it advises that holy baptism ought not be deferred for forty or eighty days, or any time according to the observance of certain people.”
