With respect to unbaptized infants, whether miscarried, aborted or dying from another cause without baptism the Church has issued a fairly recent document after several years of study.
The 41-page document, titled “The Hope of Salvation for Infants Who Die Without Being Baptized,” and authorized by Pope Benedict XVI was published in Origins, the documentary service of Catholic News Service on April 20th 2007.
In it, the Vatican’s International Theological Commission say that there are good reasons to hope that babies who die without being baptized go to heaven. The document states: that the traditional concept of limbo – as a place where unbaptized infants spend eternity but without communion with God – seemed to reflect an “unduly restrictive view of salvation.”
The church continues to teach that, because of original sin, baptism is the ordinary way of salvation for all people and urges parents to baptize infants, the document said.
But there is greater theological awareness today that God is merciful and “wants all human beings to be saved,” it says. Grace has priority over sin, and the exclusion of innocent babies from heaven does not seem to reflect Christ’s special love for “the little ones,” it says.
“Our conclusion is that the many factors that we have considered … give serious theological and liturgical grounds for hope that unbaptized infants who die will be saved and enjoy the beatific vision,” the document says.
“We emphasize that these are reasons for prayerful hope, rather than grounds for sure knowledge,” it adds.
I hope this clarifies things for jesusismyrock.
