Here is another interesting quote from a Pope prior to the man made doctrine of BOD. Even though it is not ex cathedra ( there see, I do know that there is more to understanding the faith than JUST dogmatic statements ) ....
Pope St. Siricius, 385, [Concerning the necessity of baptism] “Therefore just as we declare that respect for the Easter sacrifice [Paschal time] should not be lessened in the case of any person, in like manner we wish help to be brought with all speed to children who because of their age cannot yet speak, and to those who in any emergency are in need of the water of holy baptism, lest it should lead to the destruction of our souls if, by refusing the water of salvation to those who desire it, each of them, when taking leave of this world, should lose both the kingdom and life. Indeed whoever suffers the peril of shipwreck, an enemy attack, the danger of siege or desperation resulting from some bodily infirmity, and so asks for what in their faith is their only help, let them receive at the moment of their request the reward of regeneration that they beg for. This much should suffice for my digression on this subject; now let all priests who do not wish to be wrenched from the firmly-fixed rock of the apostles, on which Christ built his universal church, hold fast to the aforesaid rule.” (Latin found in Denzinger-Schonmetzer, Latin Edition, 1962, no. 184; an English Translation found in The Christian Faith, Sixth Revised and Enlarged Edition, Staten Island, NY: Alba House, 1996, p. 540.)
