Can you give a perspective on what led to wondering if all these quotes from authoritative docuмents, encyclicals, and from Fathers, Doctors and Saints pertaining to the fact that God, has, can and does cleanse worthy souls from Original Sin apart from water had any merit?
We all accept that general revelation ended with the death of the last Apostle, which means that all of the truths of the Catholic Faith were believed from Day 1, at least
implicitly. In this respect, I think that Catholic theology is like geometry -- one begins with a set of fundamental truths, and from there, one can, over time, derive other truths, or at least understand the more fundamental truths more deeply. In this respect, the Catholic faith is living and not dead. This is not to say that "novelties" cannot be introduced (such as Peter Abelard's idea of the
Limbo of the Children, as opposed to Saint Augustine's harsher view), but any such ideas must at least have the approbation of the Church, and certainly, the
sensus fidelium of the Faithful and be in harmony with what the Magisterium taught prior to those "novelties." In this respect, the Ordinary Magisterium is, in my opinion, independent of any particular Pope, ecuмenical Council, Doctor, Saint, or theologian of the Church; the Ordinary Magisterium simply
exists, as being the revealed truths which come from the One and Triune God. Those truths, like God Himself, are absolutely immutable, and yet, they can be understood more deeply, and so the Ordinary Magisterium itself must extend into the realm of Catholic theology and what "the theologians" taught. Not even an ecuмenical Council, in my opinion, can "change" theological conclusions which the theologians, over the course of centuries, have arrived at a certain knowledge of.
As for the salvation of non-Catholics, the Church has always allowed such as being possible. Dante, for instance, in his
The Divine Comedy, placed two pagans in Purgatory and another two in Paradise and did so without any criticism from anyone, which is significant, as Dante made some enemies during his lifetime, both secular and theological. Likewise, Bishop George Hay, in his book
The Sincere Christian, offered the possibility of "salutary repentance" at death's door for non-Catholics. So, while the Church has always taught that the Law of Baptism is an absolute precept (that is, a divine command), She has always held-out the hope that individuals who are at least virtuous with their observance of the natural law could,
perhaps, attain Heaven, which is life eternal, all the while condemning the presumption of "good hope" for such non-Catholics.
In the End, though, what is possible is not necessarily probable. We ought not to presume, which is, in my opinion, the fundamental error of the post-conciliar Church.
