This is also true for Limbo of the Infants in that simply because a child died before baptism, does not mean they deserve punishment, though they cannot achieve salvation.
The term Limbo of the Fathers was a medieval name for the part of the underworld (Hades) where the patriarchs of the Old Testament were believed to be kept until Christ's soul descended into it by his death[3] through crucifixion and freed them.
The Catechism of the Catholic Church describes Christ's descent into Hell as meaning primarily that "the crucified one sojourned in the realm of the dead prior to his resurrection.
This was the first meaning given in the apostolic preaching to Christ's descent into Hell: that Jesus, like all men, experienced death and in his soul joined the others in the realm of the dead."
Recent Catholic theological speculation tends to stress the hope, although not the certainty, that these infants may attain heaven instead of the state of Limbo.
Many Catholic priests and prelates say that the souls of unbaptized children must simply be "entrusted to the mercy of God", and whatever their status is cannot be known.
Hence, it is not immediately clear how to reconcile the mercy of God for unbaptized infants with the necessity of baptism and Catholic faith for salvation.
"[13][14] In 418, the Council of Carthage, a synod of North African bishops which included Augustine of Hippo, did not explicitly endorse all aspects of Augustine's stern view about the destiny of infants who die without baptism, but stated in some manuscripts[15][16] "that there is no intermediate or other happy dwelling place for children who have left this life without Baptism, without which they cannot enter the kingdom of heaven, that is, eternal life".
In the 12th century, Peter Abelard (1079–1142) said that these infants suffered no material torment or positive punishment, just the pain of loss at being denied the beatific vision.
Others held that unbaptised infants suffered no pain at all: unaware of being deprived of the beatific vision, they enjoyed a state of natural, not supernatural happiness.
The question of Limbo is not treated in the parts of the Summa Theologica by Thomas Aquinas, but is dealt with in an appendix to the supplement added after his death compiled from his earlier writings.
Hence, they will nowise grieve for being deprived of the divine vision; nay, rather will they rejoice for that they will have a large share of God's goodness and their own natural perfections.
[22] As stated in the International Theological Commission's document on the question: Because children below the age of reason did not commit actual sin, theologians came to the common view that these unbaptized children feel no pain at all or even that they enjoy a full, though only natural, happiness through their mediated union with God in all natural goods (Thomas Aquinas, Duns Scotus).
[29] However, throughout the 18th and 19th centuries, individual theologians (Bianchi in 1768, H. Klee in 1835, Caron in 1855, H. Schell in 1893) continued to formulate theories of how children who died unbaptised might still be saved.
By 1952 a theologian such as Ludwig Ott could, in a widely used and well-regarded manual, openly teach the possibility that children who die unbaptised might be saved for heaven.
In 1984, when Joseph Ratzinger, then Cardinal Prefect of that Congregation, stated that he rejected the claim that children who die unbaptised cannot attain salvation, he was speaking for many academic theologians of his training and background.
It then states: As regards children who have died without Baptism, the Church can only entrust them to the mercy of God, as she does in her funeral rites for them.
[36] We live by faith and hope in the God of mercy and love who has been revealed to us in Christ, and the Spirit moves us to pray in constant thankfulness and joy.
The document thus allows the hypothesis of a limbo of infants to be held as one of the existing theories about the fate of children who die without being baptised, a question on which there is "no explicit answer" from Scripture or tradition.
[42] Neither the Eastern Orthodox Church nor Protestantism accepts the concept of a limbo of infants;[43] but, while not using the expression "Limbo of the Patriarchs", the Eastern Orthodox Church lays much stress on the resurrected Christ's action of liberating Adam and Eve and other righteous figures of the Old Testament, such as Abraham and David, from Hades (see Harrowing of Hell).
Some Protestants have a similar understanding of those who died as believers prior to the crucifixion of Jesus residing in a place that is not Heaven, but not Hell.
