I dont know if there are other Catholics here who would be interested in this discussion. I am also Catholic officially, though no fundamentalist about my beliefs.
I know officially that in the CCC that the belief in Eternal Damnation is affirmed, yet there is also the affirmation that God desires all to be saved, and predestines no one to Hell. In the Rosary prayer it states “O my Jesus save us from the Fires of Hell, and Lead all Souls to Heaven, especially those in most need of your mercy”. If I recall, the liturgy and communion prayers all hope for Universal Salvation. Plus I have been told by many priests that the Church has never declared a single soul to be in hell, but has affirmed many saints in Heaven. So it seems like hopeful Universalism is a valid belief according to the official statements.
Now the question goes deeper into the exact nature of how Doctrine and theology are to be correctly understood. I know that in the Orthodox Church, doctrine is more of a matter of experience than in the West where theology became philosophized. So I guess the question is whether the teachings are supposed to be understood as something to be lived, or something to be intellectually grasped at.
I have known that people have varying degrees to how they view their faith. Some can be very “By the book” when it comes to beliefs, if thats what the catechism, Pope, Bishops, certain writing of a saint, marian apparition, Vatican Document, visionary, Liturgy, Canon Law or pious tradition says. I find that the more by the book one is, the more strongly they believe that they practice their religion the most correctly.
I guess this can happen with other churches as well, like in the Orthodox Church can do some similar things by the book, similar to Protestant bible literalism.
