How should we understand the teaching of Pope Saint John Paul II in the encyclical Redemptoris Missio [n. 10] ??
“The universality of salvation means that it is granted not only to those who explicitly believe in Christ and have entered the Church. Since salvation is offered to all, it must be made concretely available to all.”
The universal salvific will of God is a teaching of Scripture and the Magisterium. But many current opinions in salvation theology have no clear explanation for – or seem to rule out or severely restrict – the salvation of prenatals and infants who die without baptism, or for the vast majority of human persons who are non-Christian and unbaptized.
We could say that these persons would have been saved, if they had been baptized. But that position seems too weak to accord with the universal salvific will and a “concretely available” offer of salvation.
I would say that the offer of salvation includes a very broad availability of the baptisms of desire and of blood, for those without the formal Sacrament of Baptism with water.
