Whether the children who died in original sin were delivered by Christ?

Objections

Objection 1 : It would seem that the children who died in original sin were delivered from hell by Christ's descending thither. For, like the holy Fathers, the children were kept in hell simply because of original sin. But the holy Fathers were delivered from hell, as stated above (Article [5]). Therefore the children were similarly delivered from hell by Christ.
Objection 2 : Further, the Apostle says (Rm. 5:15): "If by the offense of one, many died; much more the grace of God and the gift, by the grace of one man, Jesus Christ, hath abounded unto many." But the children who die with none but original sin are detained in hell owing to their first parent's sin. Therefore, much more were they delivered from hell through the grace of Christ.
Objection 3 : Further, as Baptism works in virtue of Christ's Passion, so also does Christ's descent into hell, as is clear from what has been said (Article [4], ad 2, Articles [5],6). But through Baptism children are delivered from original sin and hell. Therefore, they were similarly delivered by Christ's descent into hell.
