The article says that limbo is " the permanent place or state of those unbaptized children and others who, dying without grievous personal guilt, are excluded from the beatific vision on account of original sin alone."
Don’t stop reading there.
Limbo was a way of discussing what happens to a soul who is not born again of water and spirit (baptized). Scripture is quite negative on one who
is not baptized (born again of water and spirit).
From that same article.
“II. LIMBUS INFANTIUM.—The New Testament contains no definite statement of a positive kind regarding the eternal lot of those who die in original sin without being burdened with grievous personal guilt. But, by insisting on the absolute necessity of being “born again of water and the Holy Ghost” (John, hi, 5) for entry into the kingdom of heaven (see
Baptism. subtitle Necessity of Baptism), Christ clearly enough implies that men are born into this world in a state of sin, and St. Paul’s teaching to the same effect is quite explicit (Rom., v, 12 sqq.). On the other hand, it is clear from Scripture and Catholic tradition that the means of regeneration provided for this life do not remain available after death, so that those dying unregenerate are eternally excluded from the supernatural happiness of the beatific vision (John, ix, 4; Luke, xii, 40; xvi, 19 sqq.; II Cor., v, 10; see also
Apocatastasis). The question therefore arises as to what, in the absence of a clear positive revelation on the subject, we ought in conformity with Catholic principles to believe regarding the eternal lot of such persons. Now it may confidently be said that, as the result of centuries of speculation on the subject, we ought to believe that these souls enjoy and will eternally enjoy a state of perfect natural happiness; and this is what Catholics usually mean when they speak of the limbus inlfantium, the “children’s limbo”
The best way of justifying the above statement is to give a brief sketch of the history of Catholic opinion on the subject. We shall try to do so by selecting the particular and pertinent facts from the general history of Catholic speculation regarding the Fall and original sin, but it is only right to observe that a fairly full knowledge of this general history is required for a proper appreciation of these facts.”… [snip]
What follows “[snip]” explains the above view with a brief sketch of the history of Catholic opinion on the subject. Limbo is not in the Catechism. It is not a doctrine of the Catholic Church.
Limbo
*Limbo is not a doctrine. The Church holds out hope for the unbaptized children. One still has to look at the reason for why there IS discussion of limbo. *
