I did not propose the position that actual physical baptism is necessary for salvation. As I stated, the Church teaches that there are three ways a person can be baptized: by water, by blood, or by desire. In the case of infants, they cannot be baptized by desire because they are incapable of having such desire. Thus, they could only be saved by water or by blood. From what I’ve read concerning baptism by blood, the person must willfully undergo the martyrdom in the name of Christ with a desire to enter the Church to be saved through a baptism by blood. And again since infants are incapable of such a desire, then that too would exclude them. Hence we are left that they can only be saved by a baptism of water. Those who have reached the age of reason, however, would then have the possibility of baptism by blood or desire.
In the document from the Limbo commission, they conclude as popes have concluded before that infants are incapable of a baptism by desire. Their conclusion is that God uses some extra-sacramental means to save them, meaning that he is thereby acting outside the sacrament of baptism rather than through the desire for the sacrament. The Council of Trent infallibly declared the following:
Chap. 4. A Description of the Justification of the Sinner, and Its
Mode in the State of Grace is Recommended796 In these words a description of the justification of a sinner is given as being a translation from that state in which man is born a child of the first Adam to the state of grace and of the “adoption of the sons” [Rom. 8:15] of God through the second Adam, Jesus Christ, our Savior; and this translation after the promulgation of the Gospel cannot be effected except through the laver of regeneration [can. 5 de bapt.], or a desire for it, as it is written: “Unless a man be born again of water and the Holy Spirit, he cannot enter into the kingdom of God” [John 3:5]. (Denz 796).
This is the infallible definition that must continue to be understood in eodem sensu (in the same sense) as the Church has always understood it to mean (as Vatican I infallibly defined is the only way dogmas can be understood). Again, no where in the 2000 year history of the Church has the Church ever taught that unbaptized infants can go to heaven. If so, please please try to disprove me. What you will find with your research is that the Church actually anathematized the Pelagians along with this teaching. Granted, the Pelagians came to this conclusion through denying original sin; nevertheless, the conclusion is the same, and the Church has always taught that one can only be justified through water baptism or at least the desire thereof. The Church has also taught infants are incapable of this desire. Therefore, logic demands, that infants cannot be justified without water baptism.
