The general subject comes up most every year in RCIA so simply ask it as others will be interested also. Here is the issue – if he church teaches baptism is a requirement, then what happens to babies lost before, or during birth, or prior to baptism? Catholic baptism is usually within weeks of births. The official answer is they are entrusted to God’s grace. Something you should know the Church acknowledges 3 forms of baptism (1) by water in the name of the Trinity, (2) by blood (martyrdom) (3) by desire. Desire may be the better answer however as it is God’s choice we simply do not know. Desire is any of man kind, baby or adult who longs for God, but has no access to God’s earthly community. So the Church does believe people of non Catholic regions can easily be saved by God’s grace through their true actions, intentions, and a baptism of desire. Similarly people who oppose the Church while longing for a relationship with God, and acting accordingly may also receive God’s grace, the key there is a true desire for God combined with a misguided belief in regard to the Church. Hope that helps
