I would just like to know the view of people
Let us remember first that Jesus Christ has not committed any sin and never lies ( 1 Peter 2: 22 ). In His statement according to apostle John He said that no one can enter the kingdom of God without being born again of water and the Spirit (John 3:5). And St. Peter attested to the right interpretation of this by saying that each one of you must turn away from your sins and be baptized so that your sins will be forgiven; and you will receive God’s gift, the Holy Spirit. For God’s promise was made to you and your children, and to all who are far away - all whom the Lord our God calls to himself (Acts 2: 38-39).
From these passages, we can not negate that there is a need for baptism by water in order to enter God’s kingdom. But what about those children who died (in the womb or after birth) without getting the sacrament of baptism? What sin have they? In Psalms 51:5 it says “I have been evil from the day I was born; from the time I was conceived, I have been sinful.” St. Paul clarifies this by saying “Sin came into the world through one man, and his sin brough death with it. As a result, death has spread to the whole human race because everyone has sinned.” (Romans 5: 12)
From this point of view, the Catholic church called it " the original sin" (You, n-Cs, you may named it as you wish), for the true church of God is given wisdom ( Ephesians 3: 10-11) for this church is the pillar and the foundation of truth ( 1 Timothy 3: 15).
We know that nothing impure can enter heaven (Rev. 21: 27).
We know that hell are for grievous sins of impenitent people and the punishment is forever. (Mat. 25:41, 46).
We know that “purgatory” [This is again another name given by the church for the punishment of venial sins and the suffering has limitations, depending on God’s will or the prayers done by the body of Christ - the church.(You, n-Cs, you may named it as you wish)] basing upon (1John 5: 17) and (1 Corinthians 3: 15).
These poor souls of the unbaptized babies who died, where will they go? They have not committed any grievous sin or venial sin but can not enter heaven basing on ( Psalms 51: 5 & Romans 5: 12). If YOU are the LORD where will you dumped these souls?
(sorry for using this word “dumped” for God is so merciful that he gave His own son to the world for the salvation of all men) (John 3: 16). The state of spiritual life here is what the early theologians called “limbo” (again, you, n-Cs, you may call it as you wish) and since this term is not yet a dogma, it can be changed, because dogmas are forever like diamonds. It is not a “nice hell” ! There’s nothing nice in hell !
