Is it possible for the church to change its teaching on something, or would that mean that it was previously in error? Or is it okay that it may have been in error, if it wasn’t an infallible teaching?
What’s coming to mind is that I have read the church used to teach that babies who died without being baptized could not be saved. Now, I understand that is not the teaching.
The Church has infallibly defined the following:
Pope Gregory X, *Council of Lyons II, *1274: “We define also that… the souls of those who depart this life in actual mortal sin, or in original sin alone, go straightaway to hell, but to undergo punishments of different kinds.” (Denz. 464)
Pope Eugene IV,
Council of Florence, “Letentur coeli,” Sess. 6, July 6, 1439,
ex cathedra: “We define also that… the souls of those who depart this life in actual mortal sin, or in original sin alone, go straightaway to hell, but to undergo punishments of different kinds.” (Denz. 693)
There can be no question that infants that die in a state of original sin only will go to hell. St. Thomas Aquinas understood there to be varying degrees of hell and the highest level was for those of infants that died without baptism. He concluded that because they did not have the capacity to attain the beatific vision that they would live there in perfect bliss unknowing of the loss of heaven and unharmed by the fires themselves. Such was then and still is a viable theological speculation. One which I personally still believe.
The Church recently put out a non-binding theological document discussing the teaching on infants the die without baptism.
vatican.va/roman_curia/congregations/cfaith/cti_documents/rc_con_cfaith_doc_20070419_un-baptised-infants_en.html The document repeatedly mentions that the reason the question was raised and discussed is that many people have worried about the states of their unbaptized children that have died, and the Church intentionally in order to placate them was seeking for another possible explanation. For 2000 years, the Church has approached divine revelation as trying to discover what has been revealed and accepting those teachings as being handed on and believed throughout the centuries. In this case, what I found particularly disturbing, was that this document instead openly states that its intention is to try to discern if other possibilities could exist in order to give consolation to the many people that worry about such.
Interestingly, this document traces the history of beliefs on the eternal destiny of these infants and in such demonstrates that the Church and Catholics never once believed or taught that infants that died without baptism could possibly be saved. In fact, the only ones, as the document records, that taught such as a possibility were heretics such as the Pelagians! This document in reaching its conclusion does not provide the heretical explanation as the Pelagians do, but it does reach the same sort of conclusion in a round about way. The document explains that there can be a
possibility for the salvation of these infants basing itself on a Scripture verse that says that God wills for all men to be saved and therefore provides to each enough grace to be saved. In the case of these infants, it says, they did not have the possibility–overlooking the fact that someone could have baptized them–and it concludes therefore that ti could be possible that God could somehow apart from the sacrament cleanse them from original sin in a way completely unknown to us. God has not provided any revelation whatsoever regarding any other way to be saved than through baptism, yet the document concludes that it could be a possibility and therefore there can be hope. The document, however, does not come near to adequately addressing the verse in Scripture that states that unless someone is born “of water and of the Holy Spirit he cannot enter the kingdom of God” (John 3:3-7). Regardless, this document is not binding as to one having to believe that it’s possible for those infants to be saved apart from baptism. It’s pure theological speculation, as God has not given us revelation in this regard. Nevertheless, one must believe and agree with the infallible declaration I quoted above. The Church has never infallibly ruled to my knowledge that there is no other possible way to be cleansed from original sin apart from the sacrament of baptism (at least by desire or blood). The Church has, however, consistently taught apart from this sacrament there is no remedy but to my knowledge no infallible definition has been attached.
Hope this lengthy analysis helps. (I admit that I have not read through this thread so if any of this information has already been stated, I apologize for any redundancy.)
