What happens to babies and young children who die?

If you're asking this from personal grief, please know first: the overwhelming historic Christian conviction, across most traditions, is one of hope and comfort, not fear, for children who die.

Most Protestant traditions have historically held that children who die before being capable of understanding and responding to the gospel are saved through Christ's grace and atonement—sometimes called an "age of accountability," recognizing that moral responsibility requires a capacity children below a certain point simply don't yet have.

Catholic teaching historically included a theological hypothesis called "limbo" for unbaptized infants, but in 2007 the Vatican's own International Theological Commission stated this had no solid theological foundation and expressed clear hope that God saves these children, while stopping short of formally guaranteeing it as settled doctrine.

David, after his infant son's death, said simply: "I'll go to him, but he will never return to me"—a statement of confident hope, not uncertainty, that has comforted grieving parents for thousands of years.
